This invention relates to sweetener compositions.
More particularly, the invention relates to sweetener compositions that control the glycemic load of a food product, that introduce natural fiber into the food product, that produce a desired sweetness profile, and that reduce the likelihood that the food product when ingested causes gastrointestinal distress.
In a further respect, the invention relates to sweetener compositions that release from a food product, a polyol and agave syrup when the food product is in the digestive tract of an individual.
The use of polyols in food products in combination with various sweeteners is well known. The sweeteners are added to an already manufactured polyol, or are added during the manufacture of a food product as an ingredient separate from the polyol. Polyols have a lower glycemic load than sucrose or high fructose corn syrup, and, as do a variety of other substances, have a lower laxation threshold than sucrose or high fructose corn syrup.
We have discovered a sweetener composition and method that enables, simply by adding the sweetener composition during manufacture of the product a food product, the achievement of a desired sweetness profile in the food product for a polyol and associated sweetener, of a desired glycemic load, of an acceptable gastrointestinal tolerance level, and of the release of a polyol and associated sweetener in the digestive tract of an individual that consumes one or more servings of the food product.
The method includes the steps of selecting at least one polyol; determining the laxation threshold in grams per day of the polyol(s); determining the desired quantity of a sweetener composition in a serving of the food product, the sweetener composition comprising the polyol(s) and agave added in solid or liquid form during the manufacture of the food product; determining the desired sweetener profile of the sweetener composition, the sweetener composition including proportions of agave and the polyol(s) to minimize the likelihood the sweetener composition will cause the food product to cause gastrointestinal distress; the adjustment of sweetness by adding a high intensity sweetener(s); admixing the polyol, agave and high intensity sweetener in powder form to produce a sweetener mixture, or admixing the polyol, agave and high intensity sweetener(s) in liquid form to produce a sweetener mixture; drying and fractioning the sweetener mixture to produce sweetener particles combined with agave; and, admixing the sweetener particles during the manufacture of the food product to produce the desired quantity of the sweetener composition in a serving of the food product.
The polyol selected can, by way of example and not limitation, comprise sorbitol, mannitol, polyglycitol syrup, polyglycitol powder, maltitol syrup, maltitol, xylitol, lactitol, isomalt, and erythritol. The glycemic load of these polyols is low in comparison to sucrose. The laxation threshold in grams/day of these polyols has been reported in technical literature as sorbitol (50), mannitol (20), polyglycitol syrup (greater than 100), polyglycitol powder (greater than 150), maltitol syrup (greater than 100), malititol (60-90) xylitol (50-90), lactitol (20-50), isomalt (50-70), and erythritol (125). The % relative sweetness of these polyols with respect to sugar has been reported in technical literature as sorbitol (60), mannitol (50), polyglycitol syrup (30-40), polyglycitol powder (less than 20), maltitol syrup (70-80), malititol (90) xylitol (100), lactitol (30-40), isomalt (40), and erythritol (60-70). Agave syrup can be as high as 120% as sweet as sucrose. In addition, the laxation threshold of agave syrup is less than most, if not all, polyols.
The desired quantity of sweetener in a food product will, of course, depend on the food product. A dessert-type food product like cake or an apple turnover will require a higher weight percent of a traditional sweetener such as sucrose, than a less sweet food product like bread. Regardless of the food product, however, the quantity of sweetener in a serving of the food product can be readily determined. This is evidenced by the fact that on most food products the serving size and quantity of sugar or other sweeteners is typically set forth on a label on the food product. The desired amount of sucrose or other sweetener utilized in the product is also readily determined either by past experience in making the produce or by current formulation of a desired product. If, for example, fifty grams of sucrose is required in a food product, then the desired quantity of a polyol, a high intensity sweetener(s) and an associated sweetener to provide an equivalent sweetness is determined by considering the serving size, by considering the laxation threshold and percent relative sweetness of the polyol, and by considering the laxation threshold and the percent relative sweetness of the sweetener associated with the polyol.
First, for sake of discussion, assume that the polyol selected is just as sweet as sucrose. Then, if for example the polyol is sorbitol and the sweetener is agave syrup, the laxation threshold of sorbitol is 50 grams/day. If the serving size is one, i.e., the food product likely will be entirely consumed in one sitting, then fifty grams of sorbitol is not utilized in the product because it is likely the product would have a laxative effect. Less than fifty grams of sorbitol is utilized in the product. For example, thirty grams of sorbitol and twenty grams of agave syrup are utilized to insure that the food product likely will not have a laxative effect. If, on the other hand, the food product includes ten servings and it is unlikely that more than a couple servings will be consumed in a day, then fifty grams of sorbitol likely could be used because only five grams of sorbitol is consumed in each serving. As a general rule, it might well be preferred to limit the amount of sorbitol to eight to ten grams per serving to reduce the risk that sufficient sorbitol will be ingested to cause laxation, although such limitations can be set as desired. High intensity sweeteners allow for such an adjustment, without reducing the target level of sweetness desired in the final product. They are therefore used to help balance between gastrointestinal effects caused by higher levels of polyols potentially used in food formulations, and desired sweetness in the food product.
Second, for sake of further discussion, it is noted that sorbitol is only 60% as sweet as sucrose. If the sweetness provided by 50 grams of sucrose is desired in the food product, either more than fifty grams of sorbitol has to be utilized, or the sorbitol has to be combined with or replaced in part by a polyol or sweetener that has a greater percent relative sweetness than does sorbitol. Consequently, a high intensity sweetener like aspartame or a natural high intensity sweetener such as stevia or rebaudioside A can be utilized, as can agave syrup which can be as high as 120% the sweetness level of sugar. Agave syrup is a recommended sweetener in the practice of the invention because it can include soluble inulin fiber up to 100%.
A food product like gum may well be able to utilize a sweetener that is 100% by weight sorbitol and high intensity sweetener(s) because the serving size is small. Other food products like cakes (or the cake mix used to make the cake), or ice cream are eaten in larger serving sizes which will include a greater quantity of sweetener and which may well, to avoid a laxation effect, require that other sweeteners be utilized in combination with the polyol.
In sum, as noted in the discussion above, after a desired quantity of sucrose (or another sweetener) in a food product and/or a serving of a food product is determined, a determination is made of the proportion of agave syrup or other sweetener such as a natural or artificial high intensity sweetener(s) and polyol necessary to provide an equivalent sweetness and to minimize the likelihood that the polyol in the food product will produce a laxation effect when the food product is consumed.
In accordance with the invention, a sweetener can be produced by infusing the polyol with agave syrup and a natural or artificial high intensity sweetener(s). This is accomplished by admixing liquid polyol, high intensity sweetener(s) and liquid agave syrup to produce a sweetener mixture. This mixture can be dried and fractioned to produce sweetener particles. The proportion of sorbitol, high intensity sweetener(s) and agave in the sweetener particles is sufficient to produce a relative sweetness that preferably is, when a weight of sweetener particles equivalent to the weight of sucrose (or of high fructose corn syrup or other sweetener(s)) utilized in a food product, equivalent to within plus or minus five percent of the relative sweetness provided by an equivalent weight of sucrose.
