Description
FIELD OF THE INVENTION

The present invention relates generally to concentrated solutions of steviol glycosides and optionally, mogrosides, suitable for preparing beverage syrups and, ultimately, beverages. Methods of preparing beverage syrups and beverages from the concentrated solutions are also provided herein.


BACKGROUND OF THE INVENTION

Stevia is the common name for Stevia rebaudiana (Bertoni), a perennial shrub of the Asteracae (Compositae) family native to Brazil and Paraguay. Stevia leaves, the aqueous extract of the leaves, and purified steviol glycosides isolated from Stevia have been developed as sweeteners desirable as both non-caloric and natural in origin. Steviol glycosides isolated from Stevia rebaudiana include stevioside, rebaudioside A, rebaudioside C, dulcoside A, rubusoside, steviolbioside, rebaudioside B, rebaudioside D and rebaudioside F.


Reb M (also called rebaudioside X), (13-[(2-O-β-D-glucopyranosyl-3-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy] ent kaur-16-en-19-oic acid-[(2-O-β-D-glucopyranosyl-3-O-β-D-glucopyranosyl-β-D-glucopyranosyl) ester], was isolated from Stevia rebaudiana and characterized:

Many steviol glycosides are present in minute quantities in Stevia rebaudiana, including Reb M which represents only about 0.05%-0.5% by weight of the leaf. Recently, it was found that Reb M could be used as a sweetener for beverages.


A concentration of at least 0.25% (% w/w) is useful for beverage syrups. Syrups having such concentrations can readily be diluted to beverages. However, crystalline rebaudioside M compositions have poor aqueous solubility and dissolution qualities in beverage formulations. For example, certain crystalline compositions containing about 75-90% rebaudioside M and about 25-10% rebaudioside D by weight cannot be dissolved above concentrations of 0.1-0.15% (% w/w) at room temperature.


Increasing the temperature of the steviol glycoside solution can increase the solubility, as can the addition of co-solvents such as ethanol. However, these are not desirable approaches compatible with the syrup manufacture process.


A reb M dosing skid has been developed to address the solubility issues when formulating syrups into full strength beverages at the bottler stage, but such equipment is expensive and must be installed at every bottler.


As such, there remains a need for methods to provide concentrated solutions of steviol glycoside sweeteners typical of beverage syrups.


SUMMARY OF THE INVENTION

The present invention generally relates to use of reb N, mogroside V and siamenoside I in certain amounts to improve the solubility of certain Stevia blends having poor solubility that are unable to be formulated at relevant beverage syrup concentrations (˜0.25-0.4 wt %). In particular, use of reb N, mogroside V and siamenoside I improves the solubility of Stevia blends containing reb M, optionally in combination with any of reb A, reb B, reb D, reb E, reb O and combinations thereof. Use of reb N, mogroside V and siamenoside I as described herein not only improves solubility, but also provides blends with similar taste profiles compared to reb M and/or RebM80. Moreover, in some embodiments, use of reb N, mogroside V and siamenoside I as described herein reduces foaming.


The present invention also generally relates to blends that exhibit superior aqueous solubility at relevant beverage syrup concentrations (˜0.25-0.4 wt %) compared to crystalline reb M or RebM80 alone. The increased aqueous solubility allows for production of beverages prepared from these concentrates and eliminates the need for a skid, heating steps and/or additional solubilizing reagents during manufacturing. The resulting beverages have a similar taste profile to beverages sweetened with reb M or RebM80. In some embodiments, the beverage syrups prepared from the concentrates exhibit less foaming compared to beverage syrups when formulated into beverages.


The blends of the present invention are capable of being formulated into concentrates having steviol glycoside concentrations required to formulate beverage syrups to prepare diet beverages, e.g. about 0.25 wt % to about 0.4 wt % (up to about 600 ppm). The concentrates are clear by visual inspection. As such, the present invention provides a concentrate having from about 0.25 wt % to about 0.4 wt % steviol glycoside content comprising water and a blend of the present invention.


The present invention also provides super concentrates comprising from about 1 wt % to about 10 wt % steviol glycoside content, prepared by (i) combining a blend of the present invention and water at room temperature to provide a mixture, wherein both the blend and water are present in amounts necessary to provide the desired steviol glycoside concentration/wt % (e.g. about 2%), and (ii) stirring the mixture at room temperature for at least 10 minutes. The resulting super concentrate is cloudy, i.e. not a solution.


The super concentrate can be diluted to a concentration typical of beverage syrups, e.g. about 0.25-0.4 wt %, providing a clear concentrate by visual inspection. This process is done without heating, addition of solubilizing agents or expensive skids. Accordingly, a concentrate is prepared by (i) diluting the super concentrate to the desired steviol glycoside concentration/wt % (e.g. about 0.25 wt %) with water and (ii) mixing for at least about 10 minutes


Beverage syrups can be prepared from the concentrate by addition of beverage syrup ingredients. Alternative, the concentrate is a beverage syrup.


Beverage syrups of the present invention can be formulated into beverages using typical equipment found in a bottling facility. A method of preparing a beverage comprising mixing a beverage syrup of the present invention with an amount of diluting water. The volumetric ratio of syrup to water is typically from about 1:3 to about 1:8.


In a particular embodiment, beverages of the present invention are reduced or zero-calorie carbonated beverages, wherein the blend is the only sweetener.

DETAILED DESCRIPTION OF THE INVENTION

I. Definitions


“Beverage”, as used herein, refers to liquids suitable for human consumption.


“Solution”, as used herein, refers to a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent). A solution is clear and does not contain particulate matter, in contrast to a suspension or cloudy mixture.


“Syrup” or “Beverage syrup”, as used herein, refers to a beverage precursor to which a fluid, typically water, is added to form a ready-to-drink beverage, or a “beverage.” Typically, the volumetric ratio of syrup to water is between 1:3 to 1:8, more typically between 1:4 and 1:6. The volumetric ratio of syrup to water also is expressed as a “throw.” A 1:5 ratio, which is a ratio commonly used within the beverage industry, is known as a “1+5 throw.”


“Steviol glycoside mixture comprising reb M”, as used herein, refers to a mixture containing at least about 80% reb M by weight, such as, for example, at least about 85% by weight, at least about 90% by weight, at least about 95% by weight, at least about 97% by weight or any range in between.


The steviol glycoside mixture comprising reb M can be RebM80. “RebM80” refers to a steviol glycoside mixture containing at least 80% Reb M by weight (the majority of the remainder is Reb D and Reb A). The total steviol glycoside content of the mixture is at least 95%. The steviol glycoside mixture comprising reb M can also be 95% reb M, i.e. a steviol glycoside mixture comprising reb M in about 95% by weight.


“Steviol glycoside mixture comprising reb A”, as used herein, refers to a mixture containing at least about 80% reb A by weight, such as, for example, at least about 85% by weight, at least about 90% by weight, at least about 95% by weight, at least about 97% by weight or any range in between. In one example, the steviol glycoside mixture comprising reb A can also be 95% reb A, i.e. a steviol glycoside mixture comprising reb A in about 95% by weight.


II. Blends


A. Reb N-Containing Blends


In some embodiments, the blends of the present invention contain reb M and reb N. In one aspect, a steviol glycoside blend comprises (i) from about 20 wt % to less than about 70 wt % of a steviol glycoside mixture comprising reb M and (ii) from about 20 wt % to about 80 wt % reb N.


The blends can further comprise other steviol glycosides including, but not limited to, reb A, reb B, reb C, reb G, reb N, reb D, reb E, reb O, reb J, isorebM, reb I and combinations thereof. Unless specified otherwise, the purity of the reb is at least about 90% by weight, such as, for example, at least about 95% by weight.


Blends of the present invention exhibit superior aqueous solubility from about 0.25 wt % to about0.4 wt % compared to a blend of only the steviol glycoside mixture comprising reb M, e.g. 95% reb M or RebM80. In one embodiment, the aqueous solubility of the blend of the present at 0.25 wt %-0.4 wt % is at least about 1.5× more than the aqueous solubility of the blend of only the steviol glycoside mixture comprising reb M, such as, for example, at least about 1.7× more or least about 2.0× more.


Blends of the present invention exhibit superior aqueous solubility at 0.25 wt %-0.4 wt % compared to the blend without reb N. In one embodiment, the solubility of the blend of the present invention has an aqueous solubility at 0.25 wt %-0.4 wt % that is at least about 1.5× more than the aqueous solubility of the blend without reb N, such as, for example, at least about 1.7× more or least about 2.0× more.


Blends of the present invention also exhibit similar (non-statistically different) taste profiles to a blend of only the steviol glycoside mixture comprising reb M. When the blends are formulated into beverages, beverages prepared from blends of the present invention have a similar taste profile to a corresponding beverage sweetened with the steviol glycoside mixture comprising reb M, e.g. 95% reb M or RebM80. For example, beverages of the instant invention have one or more of the same attributes as the corresponding beverage sweetened with the steviol glycoside mixture comprising reb M: sweetness, sweetness linger, bitterness, licorice flavor, mouthfeel, temporal profile, sweetness onset, etc. Methods of determining these attributes are well-known to those of skill in the art.


In preferred embodiments, blends of the present invention exhibit (i) superior aqueous solubility at syrup concentrations (e.g. from about 0.25 wt % to about 0.4 wt %) compared to a blend of only the steviol glycoside mixture comprising reb M, e.g. 95% reb M or RebM80, and (ii) have similar taste profiles compared to the blend of only the steviol glycoside mixture comprising reb M when formulated into a beverage.


In some embodiments, blends of the present invention also exhibit reduced foaming during bottling compared to (i) a blend of only the steviol glycoside mixture comprising reb M, e.g. 95% reb M or RebM80 and/or (ii) reb A and/or (iii) the blend without reb N. That is, when the blends are formulated into concentrates or beverage syrups at 0.25 wt %-0.4 wt % and subsequently diluted to beverages, beverages prepared from concentrates or beverage syrups containing blends of the present invention exhibit reduced foaming compared to a corresponding beverage sweetened with (i) a blend of only the steviol glycoside mixture comprising reb M, e.g. 95% reb M or RebM80 and/or (ii) reb A and/or the blend without reb N.


Foaming can be measured by both foam height (level of uniform foam throughout the circumference of the beaker when sample poured into beaker) and foam diminish time (time from when a sample hits the bottom of the container and the time when the foam diminishes to provide desired beverage volume level). Methods of determining both foam height and foam diminish time are known to those of skill in the art.


Beverages prepared from concentrates or beverage syrups containing blends of the present invention exhibit foam diminish time that is at least about 5% less, at least about 10% less, at least about 20% less or at least about 40% less compared to a corresponding beverage sweetened with (i) a blend of only the steviol glycoside mixture comprising reb M, e.g. 95% reb M or RebM80 or (ii) reb A.


It should be noted that the reduced foaming does not apply to blends containing reb B in significant (i.e. not trace) amounts.


The blends of the present invention can be formulated into aqueous solutions (concentrates) having a steviol glycoside content suitable for beverage syrups, e.g. about 0.25 wt % to about 0.4 wt %, such as, for example, about 0.25 wt %, about 0.30 wt %, about 0.35 wt % or about 0.4 wt %

III. Concentrates and Methods of Preparing Same


The present invention also provides super concentrates and concentrates comprising the blends described above.


The super concentrates have blend concentrations of about 1 wt % to about 10 wt %, such as, for example, about 2 wt %, about 3 wt %, about 4 wt %, about 5 wt %, about 6 wt %, about 7 wt %, about 8 wt %, about 9 wt and any range between. In a particular embodiment, the super concentrate has a blend concentration from about 2 wt % to about 5 wt %.


The concentrates have blend concentrations of about 0.25 wt % or more, such as, for example, at least about 0.3 wt %, 0.4 wt %, at least about 0.5 wt % or at least about 1.0 wt %. In one embodiment, the concentrates have blend concentrations from about 0.25 wt % to about 0.4 wt %. The concentrates are solutions, i.e. they are not cloudy and there are no particulates present.


The concentrates are prepared from the super concentrate. The super concentrate is prepared by (i) combining the relevant blend of the present invention and water at room temperature to provide a mixture (both the blend of the present invention and water are present in amounts necessary to provide the desired concentration/wt %) and (ii) stirring the mixture at room temperature for at least 10 minutes. The stirring time can vary depending on the amounts of both blend and water used. As such, the mixture can be stirred for at least 1 hour, at least 3 hours, at least 5 hours, at least 10 hours or at least 24 hours. The resulting super concentrate is a cloudy mixture, i.e. not a solution.


The concentrates of the present invention are prepared by (i) diluting the super concentrate to the desired concentration/wt % with water and (ii) mixing for at least 10 minutes. Again, the mixing time can vary. As such, the mixture can be stirred for at least 1 hour, at least 24 hours or at least 90 hours.


The resulting concentrate is clear by visual inspection, i.e. no particulate material is observed for at least about 6 hours after preparing. In some embodiments, the concentrate is clear by visual inspection for at least 1 day, at least 4 days, at least 14 days or at least one month.


Concentrates containing blends of the present invention at 0.25 wt %-0.4 wt % exhibit superior aqueous solubility. In one embodiment, the concentrates exhibit superior solubility compared to concentrates containing only the steviol glycoside mixture. In one embodiment, a concentrate of the present invention has an aqueous solubility that is at least about 1.5× more than the aqueous solubility of a concentrate of only the steviol glycoside mixture, such as, for example, at least about 1.7× more or least about 2.0× more.


Concentrates containing blends of the present invention at 0.25 wt %-0.4 wt % exhibit superior aqueous solubility concentrates containing the blend without reb N. In one embodiment, a concentrate of the present invention has an aqueous solubility that is at least about 1.5× more than the aqueous solubility of a concentrate of the blend without reb N, such as, for example, at least about 1.7× more or least about 2.0× more.


Concentrates containing blends of the present invention also exhibit similar (non-statistically different) taste profiles to concentrates containing the steviol glycoside mixture when formulated into beverages. That is, beverages prepared from concentrates of the present invention have a similar taste profile to a corresponding beverage prepared with the steviol glycoside mixture comprising reb M, e.g. 95% reb M or RebM80. For example, beverages of the instant invention have one or more of the same attributes as the corresponding beverage containing just the steviol glycoside mixture comprising reb M: sweetness, sweetness linger, bitterness, licorice flavor, mouthfeel, temporal profile, sweetness onset, etc. Methods of determining these attributes are well-known to those of skill in the art.


In some embodiments, concentrates containing blends of the present invention also exhibit reduced foaming during bottling compared to concentrates containing (i) only the steviol glycoside mixture c and/or (ii) reb A and/or (iii) the blend without reb N, mogroside V or siamenoside I (depending on the blend). Beverages prepared from concentrates of the present invention exhibit foam diminish time that is at least about 5% less, at least about 10% less, at least about 20% less or at least about 40% less compared to a corresponding beverage prepared from a concentrate containing (i) only the steviol glycoside mixture and/or (ii) reb A and/or (iii) the blend without reb N, mogroside V or siamenoside I (depending on the blend).


It should be noted that the reduced foaming does not apply to concentrates containing reb B in significant (i.e. not trace) amounts.


IV. Beverage Syrup and Method of Making Same


The present invention also provides beverage syrups prepared using the concentrate described herein and methods for making beverage syrups.


In one embodiment, a method of making a beverage syrup comprises combining beverage syrup ingredients with the concentrate. In one embodiment, the beverage syrup ingredients are added to a concentrate to provide a beverage syrup.


In other embodiments, the concentrate can be diluted prior to combination with beverage syrup ingredients. The dilution can be done at once or in a serial fashion. The temperature for dilution is preferably the same temperature at which the beverage syrup ingredients are formulated, typically room temperature—but not above about 70° C. for steviol glycosides or other thermally sensitive ingredients.


The skilled practitioner recognizes that beverage syrup ingredients can be added singularly or in combination. Also, solutions of dry beverage syrup ingredients can be made and used to add to the bulk quantity of water. Beverage syrup ingredients typically are added to the bulk quantity of water in an order that minimizes potential adverse interactions between ingredients or potential adverse effect on an ingredient. For example, nutrients that are temperature-sensitive might be added during a relatively low-temperature portion toward the end of the manufacturing process. Similarly, flavors and flavor compounds often are added just before completion of the syrup to minimize potential loss of volatile components and to minimize flavor loss in any form. Often, acidification is one of the last steps, typically carried out before temperature-sensitive, volatile, and flavor materials are added. Thus, flavors or flavor components or other volatile materials and nutrients typically are added at an appropriate time and at an appropriate temperature.


Beverage syrup ingredients include, but are not limited to, additional sweeteners, functional ingredients and additives.

In certain embodiments, the functional ingredient is at least one weight management agent. As used herein, “a weight management agent” includes an appetite suppressant and/or a thermogenesis agent. As used herein, the phrases “appetite suppressant”, “appetite satiation compositions”, “satiety agents”, and “satiety ingredients” are synonymous. The phrase “appetite suppressant” describes macronutrients, herbal extracts, exogenous hormones, anorectics, anorexigenics, pharmaceutical drugs, and combinations thereof, that when delivered in an effective amount, suppress, inhibit, reduce, or otherwise curtail a person's appetite. The phrase “thermogenesis agent” describes macronutrients, herbal extracts, exogenous hormones, anorectics, anorexigenics, pharmaceutical drugs, and combinations thereof, that when delivered in an effective amount, activate or otherwise enhance a person's thermogenesis or metabolism.


Suitable weight management agents include macronutrients selected from the group consisting of proteins, carbohydrates, dietary fats, and combinations thereof. Consumption of proteins, carbohydrates, and dietary fats stimulates the release of peptides with appetite-suppressing effects. For example, consumption of proteins and dietary fats stimulates the release of the gut hormone cholecytokinin (CCK), while consumption of carbohydrates and dietary fats stimulates release of Glucagon-like peptide 1 (GLP-1).


Suitable macronutrient weight management agents also include carbohydrates. Carbohydrates generally comprise sugars, starches, cellulose and gums that the body converts into glucose for energy. Carbohydrates often are classified into two categories, digestible carbohydrates (e.g., monosaccharides, disaccharides, and starch) and non-digestible carbohydrates (e.g., dietary fiber). Studies have shown that non-digestible carbohydrates and complex polymeric carbohydrates having reduced absorption and digestibility in the small intestine stimulate physiologic responses that inhibit food intake. Accordingly, the carbohydrates embodied herein desirably comprise non-digestible carbohydrates or carbohydrates with reduced digestibility. Non-limiting examples of such carbohydrates include polydextrose; inulin; monosaccharide-derived polyols such as erythritol, mannitol, xylitol, and sorbitol; disaccharide-derived alcohols such as isomalt, lactitol, and maltitol; and hydrogenated starch hydrolysates. Carbohydrates are described in more detail herein below.

2. Sensory Evaluation


The beverages were evaluated blindly by at least 5 expert panelists who work and taste steviol glycosides sweetened beverages on a daily basis. Samples were coded and randomly presented to the panelists. Panelists were instructed to eat an unsalted cracker and rinse the mouth with water before and in between samples. The maximum samples for each session was set at 5 samples to avoid fatigue. For each sample, panelists were instructed to take 3 sips, then write down their evaluation comments. Mock beverages were tasted at ambient temperature while carbonated beverages (diet lemon lime and cola) were tasted at 4° C.

Example 6
Impact of Siamenoside I and Mogroside V on Reb A/Reb M foaming





    • 1. A high intensity sweetener or a blend of two high intensity sweeteners was dissolved in DI water to make a syrup with the concentration of up to 500 ppm. Each syrup was stored refrigerated at 4.5° C.

    • 2. 45 mL of each syrup was added to a 10 oz glass bottle, and 225 mL of carbonated water (CO2 volume: 4.6) was added to make a beverage sample (3.8 CO2 volume and 5:1 throw ratio)

    • 3. Each beverage sample was refrigerated at 4.5° C. for at least an hour

    • 4. Each beverage bottle was twisted open and is inverted to pour the beverage into a 1000 mL glass beaker using a rotating clamp. The bottle was rotated until its opening hits the top of the beaker at 45° angle. This whole process was videotaped for foam height and foam diminishing time measurements.

    • 5. Foam height is measured in mL when the meniscus of the foam on the beaker wall starts to move down uniformly

    • 6. Foam diminishing time is measured in seconds between the time when a beverage hits the bottom of the beaker first and the time when the meniscus of the foam hits 350 mL line





(1) Rebaudioside A+Mogroside V, (2) Rebaudioside M+Mogroside V, (3) Rebaudioside A+Siamenosiode I, and (4) Rebaudioside M+Siamenosiode I are respectively prepared at 100, 300 and 500 ppm of total concentration in the final beverages.


Mogroside V blends with RebA or RebM


When Mogroside V was blended with RebA or RebM, both foam height and foam diminishing time were reduced with increasing percentage of Mogroside V at all three total concentrations (100, 300 and 500 ppm). However, the reduction profiles of these two different blends, namely RebA+MogV vs. RebM+MogV, differ significantly as shown in the FIGS. 1-4; RebA+MogV blends show more abrupt changes when the percentage of MogV exceeded 40% whereas RebM+MogV blends decreased gradually throughout in foam height and foam diminishing time.


Siamenoside I Blends with RebA or RebM


When Siamenoside I was blended with RebA or RebM, both foam height and foam diminishing time were reduced with increasing percentage of Siamenoside I at all three total concentrations (100, 300 and 500 ppm). However, the reduction profiles of these two different blends, namely RebA+Siamenoside I vs. RebM+Siamenoside I, differ significantly as shown in the FIGS. 5-8; RebA+Siamenoside I blends show more abrupt changes when the percentage of Siamenoside I exceeded 50% whereas RebM+Siamenoside I blends decrease gradually after 30% in foam height and foam diminishing time.
