In some embodiments, oral liquid compositions comprising dissolved gases, including dissolved nitrous oxide in combination with dissolved carbon dioxide are provided. In other embodiments, foam-creating compositions, foaming beverage compositions, and methods of preparing such compositions are provided. In other embodiments, chocolate flavored beverages comprising dissolved gases including nitrous oxide are provided.
Foaming beverages, such as root beer and root beer floats prepared from vanilla ice cream and root beer, provide a drinkable beverage having a distinctive frothy foam head. Floats also have the creamy mouth feel imparted by the addition of the ice cream. Root beer typically has the frothy foam head imparted by the combination of carbonation and foaming agents such as yucca schidigera extract.
A disadvantage of traditional floats is the inconvenience of preparation, as the separate ingredients must be combined prior to consumption. Root beer, although providing a good foamy head when poured, requires carbonation for the foam preparation. A further drawback of traditional root beer is that it does not provide a thick, creamy mouth feel as found in float beverages.
There is a need for new foaming compositions, which provide the desired advantage of convenience, foam stability, and mouth feel. The foam of such compositions would desirably be achieved with or without the need for carbonation. A further need is for the foaming composition to be prepared in a convenient form, which can be further formulated into a beverage concentrate, syrup, or final beverage.
Texture and mouthfeel are also characteristics that may be desired in chocolate beverages. Foaming compositions may be used to impart such characteristics to chocolate beverages. However, some consumers may prefer chocolate beverages that are not foaming or consumers may prefer chocolate beverages that do not include or minimize a proportion of a dairy and/or fat component. There is a need for beverages including chocolate or chocolate-flavored beverages which include a level of texture and mouthfeel and which improve the quality of chocolate flavor and aftertaste.
In recent years, the food industry has focused on products which incorporate high intensity sweeteners (non-nutritive sweeteners) as low calorie sweetener substitute to sucrose and other conventional low sweetness high calorie sweeteners. However, when high intensity sweeteners are used as the only source of sweetness in preparation of liquid oral compositions, such as beverages or pharmaceutical compositions etc., the taste and organoleptic feel with respect to many subtle features such as physical consistency, texture (such as dryness, moistness, brittleness etc.), flavour, aftertaste etc. are seen to be not equally same as that are available when sucrose or other conventional high calorie sweetener is used at same degree of relative sweetness.
The lack of same organoleptic feel arises on account of several problems such as bitter, metallic or otherwise unpleasant aftertaste etc. associated with use of high intensity sweeteners. As a result, the liquid oral compositions in which they are used are not as agreeable to taste as they are when sweetening agent is conventional high calorie sweetener alone, such as sucrose. This problem is further aggravated by the fact that high intensity sweeteners contribute only to sweetness and not to many other food properties which are contributed by conventional sweeteners, which are high calorie sweeteners, including sucrose. Hence, while high intensity sweeteners are a logical alternative choice to augment sweetness despite reduction in the use of sucrose for the purpose of reducing calories or sugar intake in the diet, doing so without losing sucrose/sugar-specific taste properties is a big challenge.
There is a need for new liquid oral compositions including high intensity sweeteners having the desired sweetness, flavour, texture and similar subtle organoleptic properties of the low calorie, high intensity sweeteners.

The beverages prepared from the foam-creating composition can contain a dissolved gas under pressure such as carbon dioxide, nitrogen, oxygen, or nitrous oxide. In some embodiments, the dissolved gas is a mixture of nitrous oxide and carbon dioxide in a volume/volume ratio of 25:75 to 75:25, specifically 40:60 to 60:40, more specifically about 50:50. The beverages can contain about 0.1 to about 5.0 volumes of a suitable gas per volume of the beverage composition, and more specifically about 1.0 to about 4.5 volumes. The gas can be provided in the beverage by forceful introduction of the gas under pressure to the beverage composition. Cooling the beverage composition allows for greater amounts of gas to be solubilized by the beverage composition.
The addition of a dissolved gas may, in some embodiments, be used to enhance the flavor, sweetness, taste, and mouth-feel of the composition. Additionally, for those embodiments that include carbonation, carbonation may lower the pH of the composition.
In one embodiment, the dissolved gas can be added to the finished, beverage composition, which contains all of the desired beverage components.
In another embodiment, the dissolved gas is added to a desired volume of water or other suitable liquid to form a water/suitable liquid containing dissolved gas. The water/suitable liquid containing dissolved gas can then be combined with a composition such as a beverage concentrate or beverage syrup to produce the finished beverage composition.
Once the beverage composition has been prepared containing a dissolved gas, it can be packaged in containers and sealed using methods, packaging, and equipment selected by those of ordinary skill in the art without undue experimentation.
In some embodiments, a dissolved gas, specifically carbonation, can be added at the point of consumption. For example, in a restaurant or convenience store, a fountain beverage consisting of a beverage syrup and a source of carbonation is prepared for imminent consumer consumption. In some embodiments, a dissolved gas other than carbon dioxide, such as nitrous oxide, or a combination of nitrous oxide and carbon dioxide can be added at the point of consumption.

In one embodiment, compositions described herein can contain herbs, minerals, and vitamins that are believed to impart the drinker a boost in energy and an overall enhanced feeling of well-being, referred to as “energy drinks”.
The herbs in the composition may include any one or more of ginkgo biloba, guarana, and ginseng. Ginkgo biloba is known to provide nutritional support for mental alertness, enhanced vitality level, circulatory health and blood vessel health. It also has high antioxidant activity that is valuable for fighting age related conditions. Ginkgo biloba is known to increase blood flow to the brain and throughout the body's network of blood vessels that supply blood and oxygen to the organ systems. It also increases metabolism efficiency, regulates neurotransmitters, and boosts oxygen levels in the brain. Benefits of enhanced circulation in the brain include improved short and long term memory, increased reaction time, and improved mental clarity.
Guarana is a concentrated source of caffeine, and consumption is believed to offer health benefits including stimulating the heart and central nervous system, enhancing alertness, and alleviating fatigue. It also has strong diuretic activity and reduces constriction of the bronchials, aiding the consumer to breathe more freely.
Ginseng is commonly used as an adaptogen, i.e. it normalizes physical functioning depending on what the individual needs (for example, it will lower high blood pressure, but raise low blood pressure). It is also used to reduce the effects of stress, improve performance, boost energy levels, enhance memory, and stimulate the immune system. Ginseng helps maintain body functions, and has been shown to increase energy, stamina, and help the body resist viral infections and environmental toxins.
In a further exemplary embodiment, the composition may include vitamin C, a water-soluble vitamin whose health benefits are well documented as it is vital to the production of collagen by the body. Vitamin C is also important because it helps protect the fat-soluble vitamins A and E as well as fatty acids from oxidation.
In a further exemplary embodiment, the composition may include one or more B vitamins, including thiamine, riboflavin, niacin, pantothenic acid, pyrodixine, biotin, cyanocobalamin, choline and/or folic acid, including the reduced forms of folic acid such as (but not only) folinic acid, calcium folinate, and methyltetrahydrafolate. The B-complex vitamins are also water soluble vitamins that aid the breakdown of carbohydrates into glucose to provide energy for the body, the breakdown of fats and proteins to aid the normal functioning of the nervous system, and muscle tone in the stomach and intestinal tract. Particular forms of B vitamins in the composition may include d-Calcium pantothenate, niacinamide, pyridoxine hydrochloride, and thiamine mononitrate.
The composition may further include inositol, which is known to be necessary for the formation of lecithin and to functions closely with folacin, Vitamins B-6 and B-12, choline, betaine, and methionine to prevent the accumulation of fats in the liver.
Caffeine is known to be useful as a cardiac stimulant and also as a mild diuretic that increases urine production. Of course, caffeine is well known as a mental stimulant, due to its affinity for binding to the adenosine receptors in nerve cells. The caffeine in the composition may include anhydrous caffeine, and may also be provided by the guarana in the composition.
One embodiment is a pre-mixed, ready-to-drink energy beverage, comprising: herbs, minerals, and vitamins that are believed to impart the drinker a boost in energy and an overall enhanced feeling of well-being; and dissolved gas consisting of a mixture of nitrous oxide and carbon dioxide in a volume/volume ratio of 25:75 to 75:25.
The herbs, minerals, and vitamins that are believed to impart the drinker a boost in energy and an overall enhanced feeling of well-being are associated with lingering negative aftertastes or off notes, including bitter, tart, metallic or chemical aftertastes. It is a further object to provide a beverage comprising dissolved gas consisting of a mixture of nitrous oxide and carbon dioxide in a volume/volume ratio of 25:75 to 75:25, wherein the dissolved N2O in an amount sufficient to reduce the lingering negative aftertaste or off notes associated with herbs, minerals, and vitamins contained in the energy drinks.
One embodiment is a method of preparing a foaming beverage comprises providing a foam-creating composition comprising a dairy composition, a hydrocolloid composition, and a foam stabilizer, wherein the dairy composition comprises a dairy protein; and dispersing the foam-creating composition in an liquid composition to form a beverage; wherein the foam-creating composition comprises a ratio of dairy protein to hydrocolloid of about 3:1 wt/wt to about 1:4 wt/wt.
The foam-creating composition, syrup, concentrate, or beverage composition can further include a sweetening agent to provide a sweet taste to the composition. Sweetening agents may include sugar sweeteners, sugarless sweeteners, and a combination comprising at least one of the foregoing.
Sugar sweeteners generally include saccharides. Suitable sugar sweeteners include mono-saccharides, di-saccharides and poly-saccharides such as sucrose (sugar), dextrose, maltose, dextrin, xylose, ribose, glucose, mannose, galactose, fructose (levulose), lactose, invert sugar, fructooligosaccharide syrups, partially hydrolyzed starch, trehalose, tagatose, sucromalt, corn syrup solids, such as high fructose corn syrup, and a combination comprising at least one of the foregoing.

RE25,959, 4,279,931 and various hydrogenated glucose syrups and/or powders which contain sorbitol, hydrogenated disaccharides, hydrogenated higher polysaccharides, and a combination comprising at least one of the foregoing. Hydrogenated starch hydrolysates are primarily prepared by the controlled catalytic hydrogenation of corn syrups. The resulting hydrogenated starch hydrolysates are mixtures of monomeric, dimeric, and polymeric saccharides. The ratios of these different saccharides give different hydrogenated starch hydrolysates different properties. Mixtures of hydrogenated starch hydrolysates, such as LYCASIN™, a line of commercially available products manufactured by Roquette Freres of France, and HYSTAR™, a line of commercially available products manufactured by Lonza, Inc., of Fairlawn, N.J., also may be useful.
In some embodiments, the sweetening agent is present in amounts of about 0.01 to about 25 wt % based on the total weight of the composition, specifically about 0.1 to about 15 wt %, more specifically 1.0 to about 10 wt %, and yet more specifically 2.0 to about 5.0 wt % each based on the total weight of the composition.

This publication is incorporated herein by reference.
The flavoring agents can be used in liquid or solid/dried form and can be used individually or in admixture. When employed in dried form, suitable drying means such as spray drying an oil can be used. Alternatively, the flavoring agent is absorbed onto water-soluble materials, such as cellulose, starch, sugar, maltodextrin, gum arabic and so forth or can be encapsulated. In still other embodiments, the flavoring agent is adsorbed onto silicas, zeolites, and the like. The techniques for preparing such dried forms are well known.

Without being limited thereto, such physical forms include free forms, such as spray dried, powdered, beaded forms, encapsulated forms, emulsions such as caramel or gum arabic emulsions, and a combination comprising at least one of the foregoing physical forms.
The particular amount of the flavoring agent effective for imparting flavor characteristics to the composition will depend upon several factors including the flavor, the flavor impression, and the like.
Suitable amounts of the flavoring agent can be selected by one of ordinary skill in the art without undue experimentation using guidelines provided. In one embodiment, the flavoring agent can be present in a beverage composition from about 0.1 to about 8.0 wt % based on the total weight of the beverage composition, specifically about 0.4 to about 6 wt %, and more specifically about 1.0 to about 3.0 wt % each based on the total weight of the beverage composition.
The flavoring agent may additionally contain weighting agents, emulsifiers, emulsion stabilizers, antioxidants, liquid vehicles, and the like.
The term “weighting agent” as used herein means any material used to adjust the specific gravity of a material whose specific gravity is lighter or lower than the specific gravity of water. In some embodiments, flavoring agents with specific gravities lower that the specific gravity of water are combined with weighting agents. Without adjusting the specific gravity of such flavoring agents or other materials with specific gravities lower than water, they may rise to the upper surface of the beverage composition. Weighting agents can include, but are not limited to brominated vegetable oil, ester gums, SAIB (sucrose acetate isobutyrate) and a combination comprising at least one of the foregoing.
Other approaches to prevent or delay materials with specific gravities lower than the specific gravity of water from rising to the upper surface of a beverage composition can be to increase the viscosity of the beverage composition or to reduce the particle size of the material with the lower specific gravity. Thus, in some embodiments, flavoring agents without weighting agents remain stable in a beverage composition.
The compositions can also contain, in addition to a flavoring agent, a flavor potentiator. Flavor potentiators are materials that can intensify, supplement, modify or enhance the taste and/or aroma perception of a composition without introducing a characteristic taste and/or aroma perception of their own. In some embodiments, potentiators designed to intensity, supplement, modify, or enhance the perception of flavor, sweetness, tartness, umami, kokumi, saltiness, and a combination comprising at least one of the foregoing.
In some embodiments, examples of suitable potentiators, also known as taste potentiators include neohesperidin dihydrochalcone, chlorogenic acid, alapyridaine, cynarin, miraculin, glupyridaine, pyridinium-betain compounds, glutamates, such as monosodium glutamate and monopotassium glutamate, neotame, thaumatin, tagatose, trehalose, salts, such as sodium chloride, monoammonium glycyrrhizinate, vanilla extract (in ethyl alcohol), sugar acids, potassium chloride, sodium acid sulfate, hydrolyzed vegetable proteins, hydrolyzed animal proteins, yeast extracts, adenosine monophosphate (AMP), glutathione, nucleotides, such as inosine monophosphate, disodium inosinate, xanthosine monophosphate, guanylate monophosphate, alapyridaine (N-(1-carboxyethyl)-6-(hydroxymethyppyridinium-3-ol inner salt), sugar beet extract (alcoholic extract), sugarcane leaf essence (alcoholic extract), curculin, strogin, mabinlin, gymnemic acid, hydroxybenzoic acids, 3-hydrobenzoic acid, 2,4-dihydrobenzoic acid, citrus aurantium, vanilla oleoresin, sugarcane leaf essence, maltol, ethyl maltol, vanillin, licorice glycyrrhizinates, compounds that respond to G-protein coupled receptors (T2Rs and T1Rs), G-protein coupled receptors (T2Rs and T1Rs), and taste potentiator compositions that impart kokumi, as disclosed in U.S. Pat. No. 5,679,397 to Kuroda et al., which is incorporated in its entirety herein by reference, and a combination comprising at least one of the foregoing potentiators. “Kokumi” refers to materials that impart “mouthfulness” and “good body”.
Sweetener potentiators, which are a type of taste potentiator, enhance the taste of sweetness. In some embodiments, exemplary sweetener potentiators include, monoammonium glycyrrhizinate, licorice glycyrrhizinates, citrus aurantium, alapyridaine, alapyridaine (N-(1-carboxyethyl)-6-(hydroxymethyppyridinium-3-ol) inner salt, miraculin, curculin, strogin, mabinlin, gymnemic acid, cynarin, glupyridaine, pyridinium-betain compounds, sugar beet extract, neotame, thaumatin, neohesperidin dihydrochalcone, hydroxybenzoic acids, tagatose, trehalose, maltol, ethyl maltol, vanilla extract, vanilla oleoresin, vanillin, sugar beet extract (alcoholic extract), sugarcane leaf essence (alcoholic extract), compounds that respond to G-protein coupled receptors (T2Rs and T1Rs), G-protein coupled receptors (T2Rs and T1Rs), and a combination comprising at least one of the foregoing potentiators.
Additional examples of potentiators for the enhancement of salt taste include acidic peptides, such as those disclosed in U.S. Pat. No. 6,974,597, herein incorporated by reference. Acidic peptides include peptides having a larger number of acidic amino acids, such as aspartic acid and glutamic acid, than basic amino acids, such as lysine, arginine and histidine. The acidic peptides are obtained by peptide synthesis or by subjecting proteins to hydrolysis using endopeptidase, and if necessary, to deamidation. Suitable proteins for use in the production of the acidic peptides or the peptides obtained by subjecting a protein to hydrolysis and deamidation include plant proteins, (e.g. wheat gluten, corn protein (e.g., zein and gluten meal), soybean protein isolate), animal proteins (e.g., milk proteins such as milk casein and milk whey protein, muscle proteins such as meat protein and fish meat protein, egg white protein and collagen), and microbial proteins (e.g., microbial cell protein and polypeptides produced by microorganisms).
In some embodiments, the foam-creating composition, concentrate, syrup, or beverage composition can include optional additives such as antioxidants, amino acids, caffeine, coloring agents (“colorants”, “colorings”), emulsifiers, flavor potentiators, food-grade acids, minerals, micronutrients, plant extracts, phytochemicals (“phytonutrients”), preservatives, salts including buffering salts, stabilizers, medicaments, vitamins, and a combination comprising at least one of the foregoing additives. Those of ordinary skill in the art will appreciate that certain additives may meet the definition or function according to more than one of the above-listed additive categories.
The compositions described herein may optionally comprise a salt. Suitable salts include, for example, alkali or alkaline earth metal chlorides, glutamates, and the like. For example, monosodium glutamate, potassium chloride, sodium chloride, and a combination comprising at least one of the foregoing salts. The salts can be added to a beverage as a flavor potentiator as previously described.
The term “food-grade acid,” as used herein, encompasses any acid that is acceptable for use in edible compositions.
The compositions may optionally further contain a food-grade acid. Suitable food-grade acids for use in the composition include, for example, acetic acid, adipic acid, ascorbic acid, butyric acid, citric acid, formic acid, fumaric acid, glyconic acid, lactic acid, malic acid, phosphoric acid, oxalic acid, succinic acid, tartaric acid, and a combination comprising at least one of the foregoing food-grade acids. The food-grade acid can be added as acidulant to control the pH of the beverage and also to provide some preservative properties, or to stabilize the beverage.
The foam-creating composition may contain an amount of food-grade acid of about 0.06 to about 1.0 wt % based on the total weight of the foam-creating composition, specifically about 0.1 to about 0.8 wt % In some embodiments, the ready-to-drink beverage comprises about 0.06 to about 0.6 wt % food-grade acid, based on the total weight of the beverage.
The pH of the beverage may also be modified by the addition of food-grade compounds such as ammonium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate, and the like, and a combination comprising at least one of the foregoing. Additionally, the pH of the beverage can be adjusted by the addition of carbon dioxide. Further, in some embodiments, buffering agents including, but not limited to citrates such as sodium citrate, can be used to adjust the pH of the beverage.
In some embodiments, the tartness of the composition may be varied by selecting and combining acids to provide a desired tartness perception.
Some factors to consider in determining a desired tartness include, for example, the acid's dissociation constant, solubility, pH, etc. These variables can be measured by measuring the titratable acidity of the beverage composition. Tartness can also be measures by standard sensory science techniques such as those described by H. Moskowitz in Sourness of Acid Mixtures as published in The Journal of Experimental Psychology, April 1974; 102(4); 640-7 and in Ration Scales of Acid Sourness as published in Perception and Psychophysics; 9:371-374, 1971.

l In some embodiments, the beverage composition is subject to homogenization conditions, such as high pressure homogenization, to provide a homogenous beverage composition. Any conventional homogenization equipment can be employed, such as equipment available from APV Gaulin, Alfa-Laval or Niro Soavi.
In some embodiments, the beverage composition is pasteurized to sterilize the product by destroying unwanted microorganisms. Exemplary processes to destroy or remove unwanted microorganisms include hot-filling, aseptic packaging, ozonation, radiation (e.g., ultraviolet light or gamma rays), membrane permeation, pulsed electric field, sonication, and the like.
Depending upon the components of the beverage composition, pasteurization can be effected at different temperatures. For dairy, grain, fruit or vegetable-based beverage compositions a pasteurization temperature of about 60 to about 80° C. can be sufficient, specifically about 65 to about 75° C., and more specifically about 68 to about 72° C. More specifically, the fruit or vegetable-based beverage composition can be pasteurized by heating to the desired temperature for about 6 about 15 minutes in an aseptic environment, more specifically about 8 about 12 minutes, and yet more specifically about 9 about 11 minutes.
The beverage composition can be bulk pasteurized and then filled into a desired beverage container. In some embodiments, the beverage composition is filled into the desired beverage container, such as a glass bottle, and then subjected to the pasteurization conditions.
Alternatively, in some embodiments, the beverage composition is hot-filled into the desired beverage container. More specifically, the beverage composition is filled into the beverage container at temperatures sufficient to sterilize the composition in the container, for example about 85° C. After several minutes, the container and composition can be cooled down to about 32 to about 38° C.
In other embodiments, the beverage composition, containing prepasteurized foam-creating composition, is cold-filled into a desired beverage container. In such embodiments, preservatives can be added to the beverage composition. More specifically, cold-filling the beverage involves adding the beverage to the beverage container at ambient temperature (e.g., about 21° C.). Preservatives, such as those described herein, can be added to the composition to lower the pH level of the composition. Desirable pH values can be about 3 to about 4.5. In some embodiments, the pH is about 4 or less, specifically about 2 or less. Cold-filling with preservatives is used in some embodiments as an alternative to pasteurization.
In some embodiments, aseptic processes can be used to provide shelf stable, sterile beverages without the use of preservatives. The aseptic process involves sterilizing the beverage composition using an ultra-high temperature process that rapidly heats, then cools, the beverage composition. The time for sterilization can be about 3 to about 15 seconds at temperatures of about 195° F. (90.6° C.) to about 285° F. (140.6° C.). The sterilized beverage composition is then filled into sterilized aseptic packages within a sterile environment. Exemplary aseptic packages include a laminated container prepared from paperboard, polyethylene, e.g., low-density polyethylene (innermost layer), and aluminum; high density polyethylene (HDPE) plastic bottles; and the like.
The beverage compositions can be packaged in a container as ready-to-drink, shelf stable beverage products. Any type of beverage container can be used to package the beverage composition including glass bottles, plastic bottles and containers (e.g., polyethylene terephthalate or foil lined ethylene vinyl alcohol), metal cans (e.g., coated aluminum or steel), lined cardboard containers, and the like. Other beverage packaging material known to one of ordinary skill in the art can be used.
In one embodiment, the packaged beverage can include a foam-creating device to further froth the beverage upon opening the beverage container. The use of the device would allow for the formation of a frothy foam head on the beverage without the need for the consumer to shake the container prior to opening. Such devices are known in the art, typically for beer or beer-related beverages, and especially those beverages containing sufficient amounts of dissolved gasses. These devices can comprise containers with distinct chambers, foam-creating features, devices at the container opening, container inserts that function to introduce a stream of gas to the surface of the beverage in the container, features to create a nucleation site in the container to allow for dissolved gases to escape from the beverage, and the like. Exemplary containers and devices can be found in U.S. Pat. Nos. 4,279,938, 4,832,968, 5,009,901, 5,290,574, 5,334,400, 5,660,867, 5,714,186, 5,827,555, 5,980,959, and 6,896,920; and WO2004/054896.
Beverages prepared from the foam-creating composition disclosed herein provide a thick, creamy head of foam when the beverage is shaken and then poured. The step of shaking or agitating the beverage prior to pouring can be omitted if the beverage is prepared with dissolved gas, such as carbonation, as the release of the gas provides sufficient agitation to result in a foam head. The foam formation can be enhanced with the use of a foam-creating device as discussed above.
Beverages prepared from the foam-creating composition and further having dissolved gas retain the dissolved gas longer than similar beverages that do not contain the foam-creating composition. In one embodiment, the amount of dissolved gas present in a beverage prepared from the foam-creating composition changes by less than about 25% when comparing the amount of dissolved gas in the beverage freshly poured at an initial temperature of 5° C. to the amount of dissolved gas in the beverage after resting at 20° C. for 1 hour post pouring.
Additionally, beverages prepared from the foam-creating composition provide a longer retention of foam head as compared to beverages that do not contain the foam-creating composition or even beverages containing only known foam enhancers such as yucca. In some embodiments, pouring the beverage at 40-50° F. (4.4-10° C.) into an open container and waiting three minutes after transfer of the beverage to the container produces a liquid phase and a foam phase, wherein a ratio of the foam phase volume to the liquid phase volume is about 0.1:1 to about 1:1, specifically about 0.2:1 to about 0.5:1. A procedure for determining the ratio of foam phase volume to liquid phase volume is provided in the working examples below.
In one embodiment, a method of stabilizing foam in a beverage comprises preparing a beverage composition, a bottling syrup, a fountain syrup, or a beverage concentrate to comprise an amount of a foam-creating composition to stabilize a foam in a beverage, wherein the foam-creating composition comprises a dairy composition, a hydrocolloid composition, and a foam stabilizer, wherein the dairy composition comprises a dairy protein; and wherein the foam-creating composition comprises a ratio of dairy protein to hydrocolloid of about 3:1 wt/wt to about 1:4 wt/wt.
In one embodiment, a method of creating foam in a beverage comprises preparing a beverage composition comprising an amount of a foam-creating composition; optionally shaking the beverage composition; and dispensing the beverage to form a foam; wherein the foam-creating composition comprises a dairy composition, a hydrocolloid composition, and a foam stabilizer, wherein the dairy composition comprises a dairy protein; and wherein the foam-creating composition comprises a ratio of dairy protein to hydrocolloid of about 3:1 wt/wt to about 1:4 wt/wt.
In one embodiment, kits can be provided containing the foam-creating compositions or beverage compositions described herein along with a communication that the composition creates foam. In specific embodiments, the communication informs the consumer that dispensing the composition creates foam; or shaking and dispensing the composition creates foam. The communication can be in any format that can communicate the foam creating property of the compositions. Exemplary forms of communication include printed matter (e.g., as an advertisement, product literature, flyer, label, container, etc.).
In one embodiment, a kit comprises a foam-creating composition comprising about 2 to about 95 wt % dairy composition based on the total weight of the foam-creating composition, wherein the dairy composition comprises a dairy protein; a hydrocolloid composition; and a foam stabilizer; wherein the foam-creating composition comprises a ratio of dairy protein to hydrocolloid of about 3:1 wt/wt to about 1:4 wt/wt.; and communication that use of the composition creates foam.
In another embodiment, a kit comprises a pre-mixed, ready-to-drink foaming beverage comprising a foam-creating composition comprising a dairy composition, a hydrocolloid composition, and a foam stabilizer; wherein the foam-creating composition comprises about 2 to about 95 wt % of the dairy composition based on the total weight of the foam-creating composition, and wherein the dairy composition comprises a dairy protein; and wherein the foam-creating composition comprises a ratio of dairy protein to hydrocolloid of about 3:1 wt/wt to about 1:4 wt/wt; and communication that dispensing the composition creates foam.
The features and advantages are more fully shown by the following examples, which are provided for purposes of illustration, and are not to be construed as limiting the invention in any way.
The components provided in Table 1 are combined to form a uniform mixture containing about 5.32 wt % dairy protein and about 9.44 wt % total hydrocolloid to result in a foam-creating composition having a dairy protein to total hydrocolloid ratio of about 1:1.77.
The foam creation/stabilization composition can be used to prepare a beverage by the addition of water, juice, milk, a chocolate flavored ingredient etc. with stirring. The resulting beverage can be packaged in a beverage container, where the beverage forms a foamy head when shaken and poured. If the beverage is carbonated or contains dissolved gas under pressure, the shaking step may be omitted.
A ready-to-drink, foaming beverage is prepared from the components of Table 2. The pectin, propylene glycol alginate, and gum arabic are dry-blended together with sugar to form a dry blend. The dry blend is then added to one-fifth the quantity of water with mixing. The remaining ingredients are added in the order shown in Table 2 to form a mixture. The remaining quantity of water is carbonated to 2.0 volumes of CO2 and the mixture is added to the carbonated water to form the final beverage. The final can be packaged in a beverage container to form a ready-to-drink beverage product.
The beverage of Example 2 is tested for foam stabilization. Fifty milliliter aliquots each of the beverage of Example 2 and a comparative example beverage having no pectin, propylene glycol or gum Arabic are separately shaken for an equivalent time and rate. Both beverages are refrigerated at 5° C. overnight prior to the test. The shaken beverages are each poured into a separate standard 100 ml graduated cylinder and the volume of the foam is determined. After the beverages are allowed to remain at room temperature (˜20° C.) for one hour, the volume of the foam is again measured. The beverage of Example 2 provides a significant retention of foam volume as compared to the comparative example.
The beverage of Example 2 is prepared with a 50:50 combination of carbon dioxide and nitrous oxide. It was unexpectedly found that the foam volume of the resulting beverage is retained significantly longer than the foam volume retained for the beverage of Example 2.
This example illustrates the determination of foam phase volume and liquid phase volume for a freshly poured beverage. A bottle containing about 349-355 milliliters (10.8-12.0 U.S. fluid ounces) of beverage and 2.5 volumes of dissolved gas was cooled to a predetermined temperature of 40 or 50° F. (4.4 or 10.0° C.). A 500 milliliter graduated cylinder was cleaned, rinsed, and dried, then fitted with an adapter to accommodate the beverage bottle. The adapter supports the beverage bottle on graduated cylinder and allows the pressure within the apparatus to equalize with ambient pressure (about one atmosphere). Images corresponding to two views of the adapter are provided as
This procedure was conducted for ready-to-drink beverages having the composition of Example 2 above and additionally containing 2.5 volumes of dissolved gas. The initial temperature of the beverage and the volume ratio of carbon dioxide (CO2) and nitrous oxide (N2O) in the gas were varied. Twelve samples were tested for each combination of temperature and gas composition. Results are presented in Table 3. Averages and standard deviations for each condition are presented in Table 4.
The results demonstrate the ability of combinations of carbon dioxide and nitrous oxide to provide a stable foam across a range of blends. This allows formulation flexibility to adapt the gas blend for reasons such as cost.
This example illustrates the incorporation of foam stabilizing agents into the composition. The compositions summarized in Table 5, where component amounts are expressed in parts by weight, is prepared according to the procedure described for Example 2. Quillaia extract and yucca schidigera extract are each incorporated at 510 parts per million by weight.
This example was conducted to understand the impact of different dissolved gas blends on the consumer acceptance and sensory attributes of a gently carbonated lemon tea. For the purpose of this Example, the “product” refers to the five gently carbonated lemon teas tested. The product was evaluated by a consumer test and using an expert panel trained to evaluate product sensory attribute similarities and differences.
A panel of 100 consumers was convened to evaluate the sensory impact of carbon dioxide versus nitrous oxide in a gently carbonated lemon tea. The panel comprised an equal number of both male and female consumers aged 18 to 55. Each consumer evaluated five lemon tea product samples, including a still tea (labeled as “Lemon Tea”), as well as four carbonated teas (labeled “Gently Carbonated Tea). The lemon tea product samples containing carbon dioxide and/or nitrous oxide containing 2.5 volumes of dissolved gas. The following lemon tea product samples were evaluated.
MG1: Still Product (no carbonation)
MG2: 100% dissolved carbon dioxide
MG3: 50% dissolved carbon dioxide: 50% dissolved nitrous oxide
MG4: 25% dissolved carbon dioxide: 75% dissolved nitrous oxide
MG5: 75% dissolved carbon dioxide: 25% dissolved nitrous oxide
The lemon tea products were presented in a sequential monadic, balanced presentation order. The lemon tea products samples tested contained four refrigerated ounces per sample, following a carbonated serving protocol (product consumed immediately after pouring). Table 7 below summarizes the consumer acceptance and sensory attributes oft gently carbonated lemon tea products.
Referring to Table 7,
the lemon tea product containing 50% dissolved carbon dioxide and 50% dissolved nitrous oxide was reported as being comparable to the still tea for lemon flavor, tea flavor and balance of lemon to tea flavor, sweetness, and tartness. Further, the increasing nitrous oxide translated into an increase in perceived sweetness. Results among each demographic group (males, females, 18-30 year olds, 31-55 year olds) mirrored the results by total.
A 14 member Trained Descriptive Sensory Panel was convened to evaluate product sensory attribute similarities and differences, using the Tragon QDA® research method. Tragon QDA® is a trained panel research method that measures sensory attribute similarities and differences.
Each panelist evaluated five lemon tea product samples, including a still tea (labeled as “Lemon Tea”), as well as four carbonated teas (labeled “Gently Carbonated Tea). The lemon tea product samples containing carbon dioxide and/or nitrous oxide containing 2.5 volumes of dissolved gas. The following lemon tea product samples were evaluated.
MG1: Still Product (no carbonation)
MG2: 100% dissolved carbon dioxide
MG3: 50% dissolved carbon dioxide 50% dissolved nitrous oxide
MG4: 25% dissolved carbon dioxide: 75% dissolved nitrous oxide
MG5: 75% dissolved carbon dioxide: 25% dissolved nitrous oxide
A 4 oz. product serving was presented in 5 oz. clear plastic cups at a serving temperature of 42+/−2° C. The 14 member panel evaluated each product 3 times with breaks provided between products. During each break, panelists cleansed their palates with unsalted crackers and room temperature water.
At the onset of the study, the 14 member panel convened during language development sessions to discuss and agree upon a common language to fully describe the product included in the test. The panel identified 60 sensory terms, including 4 terms directed to appearance, 17 terms directed to aroma, 21 terms directed to flavor, 3 terms directed to mouthfeel, and 15 terms directed to aftertaste/after effect. The 60 sensory terms are provided in Table 8.
The descriptive results of the 14 member Trained Descriptive Sensory Panel are summarized in Table 9.
The descriptive results provided by the 14 member Trained Descriptive Sensory Panel confirm and support the consumer test results provided in Example 126 above. In particular, the 100% carbon dioxide variant was liked the least due to higher tart and bitter, high mouthfeel (drying, burning and residue). As the amount of carbon dioxide decreased, the tart, bitter flavor, drying, burning mouthfeel and off notes decreased.
The 14 member Trained Descriptive Sensory Panel further reported that the 100% carbon dioxide variant had noticeable off notes including metallic off notes and chemical off notes. Increasing amounts of nitrous oxide reduced the metallic off notes.
Further, the increasing nitrous oxide translated into an increase in perceived sweetness.
Among the carbonated variants, the lemon tea product containing 50% dissolved carbon dioxide: 50% dissolved nitrous oxide was reported as having the most balanced profile, which confirms the results of the consumer test results.
A 12 member Trained Descriptive Sensory Panel was convened to evaluate product sensory attribute similarities and differences, using the Tragon QDA® research method described previously. Each panelist evaluated two chocolate beverage product samples, including a first chocolate-beverage soda with dissolved carbon dioxide and a second chocolate-beverage soda including a mixture of nitrous oxide and carbon dioxide in a volume/volume ratio of about 50:50. The total volume of dissolved gas in the first chocolate-beverage soda was about 2.4 volumes. For the second chocolate-beverage soda, the total volume of dissolved gas in the 50:50 mixture of nitrous oxide and carbon dioxide was about 3.9 volumes.
The two chocolate beverages were each prepared using a fudge-flavored chocolate base as shown in Table 10.
Each of the chocolate beverages was prepared by dilution of the beverage base in water. The base was diluted with addition of about 1 part of the base to about 5 parts water.
A 4 oz. product serving was presented in 5 oz. clear plastic cups at a serving temperature of 42±2° C. The 12 member panel evaluated each product 3 times with breaks provided between products. During each break, panelists cleansed their palates with unsalted crackers and room temperature water.
At the onset of the study, the 12 member panel convened during language development sessions to discuss and agree upon a common language to describe the product included in the test. Above any terms previously defined in Table 8, the panel identified various terms as defined in Table 11.
The descriptive results of the 12 member Trained Description Sensory Panel are summarized in Table 12.
