The present invention generally relates to binders for food products and more specifically relates to a non-sweet binder composition for use in meal replacement products including nutritive edible bars that provide meal-like eating experience.
Consumers are not only concerned about nutritional and potential health benefits of food products, but also their organoleptic attributes, which are highly valued and often act as major drivers of sale and consumption of food products. Nutrition bars including protein bar, meal bar, energy bar, weight loss bar, bite size nutritional food products, and the like, constitute a substantial portion of meal replacement products and healthy snacks.
A variety of components including combinations of sugars and carbohydrates, proteins, fats and oils have traditionally been used as binders to form compact, ready-to-eat food products including nutrition bars. The binding process customarily used to hold individual components together in nutritive bars and meal replacement products usually require high quantities of sugars and/or syrups as binding agents.
Attempts to develop non-sweet and/or savory food products using conventional binder constituents with minimal amounts of sugar, syrups and/or sugar alcohols for binding requirements have been unsuccessful because certain level of sweetness is still retained in the final food product. As a result, consumers of edible nutritive bars or meal supplement bars have had to accept high levels of sugar/syrup content and sweet taste as traits associated with edible bars, in spite of their desire to limit sugar intake.
There is a long felt need to provide non-sweet binders which can be used in meal replacement products, particularly nutritive bars including savory edible bars which are largely limited to very few niche offerings. To overcome the need to add sugary binders, these food products have essentially relied on using increased amounts of fatty ingredients that are solid at room temperature, for example: peanut or almond butter and/or milled grains and its flour are used to form dough that are blended with other ingredients of the nutrition bar. The blended products are then baked, typically with addition of baking powder. Consequently, these meal replacement products are usually high in fat and/or carbohydrate content and the final product may possess the consistency of baked and dried dough product embedded with grounded ingredients.
The sweet flavor resulting from the use of existing syrup and sugar based binders, and high calorie value resulting from the added fat or oil based binders, along with the lack of satisfactory non-sweet binder technology have severely limited meal replacement product offerings in the marketplace. Savory meal replacement bars and similar nutritional food products with flavors that provide a real meal experience is an unmet consumer need. For example, unlike salty snacks, nuts and cheese that are often paired with and used to complement savory meals and beverages such as wine and beer, the sweetness of existing nutritive bars limit their use occasions and ability to be consumed as accompanying food items with meals and beverages. They are often consumed alone, consumed along with neutral flavored or sweet drinks and/or stimulating drinks such as coffee, or as dessert-like after meal product. Additionally, underserved cohorts such as vegans, ovo-vegetarians and lacto-vegetarians currently have very limited options, due to the dominating presence of dairy and egg based products in meal replacement product market.
In light of the foregoing description, the following prior art patents are cited as pertinent to provide insights into previous work on the development of binding systems used for developing non-sweet and savory shelf stable meal replacement food products.

Thus, there still remains a need for non-sweet food binder options that can be used for the development of non-sweet, low calorie, meal-like snacks and meal replacement products.
The present invention relates to food binder compositions that can be advantageously used in the development of non-sweet and savory food products including meal replacement food products such as nutrition bars or energy bars.
In an embodiment, the present invention relates to a non-sweet binder for a food product, the binder composition comprising: at least one starch component, about 1 to 20 percent by weight, dispersed in an aqueous medium forming an aqueous binder solution, wherein the aqueous binder solution is heat treatable to achieve a desired viscosity that allows cohesion of a plurality of ingredients and shaping of the food product without substantial modification in nutritional value.
In another embodiment, the present invention relates to a meal replacement food product comprising the aqueous based non-sweet binder and a plurality of dried food components selected from a group consisting of nuts, seeds, grains and seasoning. The food product is substantially free of gluten, added sugar, hydrolyzed polysaccharides, sugar alcohols, colloidal substances and fats but offers a good source of protein, fiber and essential oils and less calorific value contributed by the non-sweet binder.
The term “binder” as used herein refers to a material or substance that is incorporated into a food product for the purpose of holding or drawing other material together to form a cohesive whole product from loosely assembled ingredients. Because the binder described herein is intended to be used in the production of food, it is preferably a food-grade binder. “Savory” is intended to mean non-sweet flavors that are aromatic, salty, cheesy and/or spicy. “Meal replacement product” as used herein refers to nutrition bars, nutritive bars, energy bars, granola bars, meal bars, protein bars and similar products that are bite size, square, spherical and/or irregular shaped.
According to an embodiment, the present invention relates to a non-sweet binder composition comprising of a starch component, physically modified or in its native form, dispersed in an aqueous medium resulting in a binder solution. The aqueous based binder composition, constitutes the sole and/or main added binder for bonding together a plurality of ingredients such as nuts, seeds, grains, and seasoning for preparation of meal replacement products. The non-sweet binder composition thereby eliminates the need to add other conventional binding materials such as high calorie sugars and syrups, sugar alcohols, gums, hydrolyzed polysaccharides, solubilized fibers, fats and/or oil, etc. In addition, the non-sweet binder does not require the food product ingredients to be ground, pulverized or finely chopped before mixing.
The simplicity provided through the non-sweet binder composition and its preparation has not been previously leveraged for its binding capability as a sole functional added binder for bonding ingredients in aggregated food products such as edible bars and meal replacement products. Since the binder by itself is bland and/or non-sweet with minimal impact on the flavor of the final product, it can be advantageously used in the development of diverse flavored food products such as savory flavored snacks and/or low calorie snacks.
The non-sweet binder composition of this invention preferably comprises a starch content of about 1 to about 20%, more preferably about 2% to about 7% by weight of the aqueous binder solution. The starch component can be from a single source or multiple sources mixed together as components of the binder. While the starch may be selected from a variety of plant sources including tubers, roots, rhizomes, corms, stems, seeds, grains and legumes, the preferred starch source is tapioca root. For example, the starch component is obtained from corn, lotus root, taro root, rice, tapioca, arrowroot, potato, kudzu, etc. Aqueous component of the binder comprises water or any food grade aqueous solution including fruit and vegetable juices/purees, fermentation products, broth, stock solutions, etc. The binder composition may include optional ingredients such as, flavorings, oils, sweeteners, emulsifiers, micronutrients, vitamins, minerals, coloring, and health and wellness enablers such as bio actives, essential fatty acids, and antioxidants. The binder compositions described herein allow the cohesion of the plurality of ingredients and also facilitate the shaping of the final food product such as a nutritive bar, without increasing its calorie content. Prepared food products incorporated with the above binder composition, will not disintegrate over time nor would they lose their structural form upon freezing, refrigeration or thawing.
According to one embodiment, the starch is dispersed in its pre-gelatinized form at an ambient or near ambient temperature to produce a binder composition with desired viscosity. The said binder, when used in the preparation of snack bars typically would contribute from less than 2 to about 15 calories per 40 g serving of the food product unlike most sugar-based binders which forms 25-50% of the food product and contribute about 60 to 90 calories per 40 gram serving of the food product.
In another embodiment, the aqueous binder composition is heated, microwaved or treated in a manner that results in starch gelatinization and/or modification until a desired viscosity is reached that can cause aggregation of food ingredients or edible components forming a food product.
According to another embodiment, an aqueous mixture, equivalent to the aqueous component of the binder composition, is added to an admixture of starch powder and dry food ingredients. The amount of ingredients could be in ratios that allow the resulting blended material to achieve a desired viscosity for aggregation at ambient temperature such that it permits shaping of the food product. The binder composition can also be subjected to treatment at controlled temperatures to modify viscosity to an appropriate level. In an embodiment, the non-sweet binder composition, comprises between about 85% to about 99% by weight of moisture content.
According to an embodiment, the binder preferably comprises a combination of pre-gelatinized and native starch. The pre-gelatinized starch causes an increase in viscosity of the binder at ambient temperature and thus facilitates aggregation of the food components without the need to heat the binder mixture. Presence of the native starch permits addition of the right amount of pre-gelled starch needed to hold dry ingredient components together at ambient temperature. The subsequent gelatinization of the native starch that occurs during the heating and drying process helps to rapidly attain a viscosity needed to bind the ingredients together. This native starch also helps to pull water away from the other ingredients while being heated and causes a decrease in drying time.
In another embodiment, the present invention relates to a meal replacement product comprising the aqueous based binder composition mixed with dry food ingredients consisting of nuts, seeds, grains and seasoning. The preferred binder concentration is about 5 to 20% of the total ingredient weight. The said ingredients will preferably include seeds and plant components, such as mustard seed, flax seed, chia seed, cactus, seaweed, etc., with natural mucilage coatings and/or food items such as precooked and dehydrated grains including puffed/extruded quinoa, oat, rice, millet, sorghum, amaranth, buckwheat, corn, teff etc., that produce mucilaginous substances/coatings upon heat treatment. The mucilaginous substances and starch component act synergistically, to increase the binding capacity of the aqueous based binder composition. The important role of mucilaginous coating is evidenced by the lack or minimal binding that occurs when the starch binders are added to a blend of non-mucilaginous substance comprising ingredients such as mixed nut pieces.
Gums and mucilage are known to act in synergy with starch through electrostatic interactions, which play an important role in altering pseudoplasticity of starch pastes, causing higher paste viscosities at low shear rates and enhanced binding properties. However, until this invention, these properties have not been applied to cause aggregation and binding of loosely assembled food ingredients to produce savory and/or non-sweet snacks and food products. Those skilled in the art will understand that this binder component of the food product can be derived from a number of other sources comprising combinations of isolated polysaccharides (e.g. gums, mucilages and pectin), mucilaginous plant extracts and products (cactus, aloe vera, kelp, okra, Chinese yam, etc.), solubilized fibers with storage polysaccharides (e.g. starch, fructans and galactomannans), algae and/or microorganisms.
One preferred method for altering the viscosity of binder to a desired level that causes bonding of ingredients in the food product involves heating the aggregated food product to increase viscosity simultaneously during the drying process. The preferred heating temperature of the aggregated or compacted food product is about 170 to 350 degree F. to obtain a bound food product of water activity below 0.6. In an embodiment, additional starch can be optionally added to the dry ingredients, prior to mixing with the binder which helps to pull moisture away from the ingredients. Optional coating and modifications to the texture and flavor of food products can be accomplished by the addition of low sugar syrups, the preferred range of which is DE 25 to DE 35. Shaping of the final food product by cutting or slicing can be carried out prior to heating the aggregated product to cause permanent binding or after the heating and drying process. The shape of the formed product is not easily changed, except by cutting or slicing. The combined use of food ingredients that are crunchy such as nuts, seeds, puffed/extruded grain products and addition of herbs and spices to the binder will result in a savory and crunchy final food product.
The above preferred components and process will typically yield a food product with about 0 to 2 grams of sugar in a 40 gram serving of product. An additional attribute of the food product is the visible food components that serve as visual cues for a healthy snack. In addition to the use of non-sweet binder, the meal replacement products offers distinctly different flavor profiles from majority of those currently exist in the market. The meal replacement food products comprising increased quantity of nuts and seeds facilitates further creation of consumer outlets for these healthy foods. Nuts and seeds are nutrient-dense and are reliable sources of essential nutrients such as essential oils, protein, fiber and complex carbohydrates, vitamins, minerals and phytochemicals. The preferred ingredients of the above food product provide fat compositions with over 75% unsaturated mono and polyunsaturated content, and comprises very low sugar content, low glycemic index, gluten free, and are good sources of fiber and protein. The food product will also provide better options for underserved cohorts such as vegans, lacto and/or ovo-vegetarians, gluten sensitive individuals and those trying to limit their sugar consumption.
