Abstract: The invention relates to a method for producing microspherical crystallites with a uniform spherical shape and an extremely narrow size distribution. Said crystallites consist wholly or partially of a linear water-insoluble polysaccharide, preferably of 1,4-&agr;-D-polyglucane, have a degree of crystallinity of >80% and can contain additional polymers and/or active ingredients, which are in particular biodegradable. They are particularly suitable for the controlled release of active ingredients. They are produced by fusing 1,4-&agr;-D-polyglucane or the polysaccharide in water, introducing the fusion into a precipitant, cooling the mixture and separating the particles that have formed.

Abstract: Superior quality, clean-tasting food grade polydextrose is prepared by reacting glucose or glucose-containing materials such as hydrolyzed starch with a polyol such as sorbitol in the presence of low levels of a polycarboxylic acid such as citric acid. In one embodiment, polydextrose is prepared by reacting glucose or glucose-containing materials such as hydrolyzed starch with a polyol such as sorbitol in the presence of low levels, i.e., from about 0.03% to about 0.1% citric acid at a temperature of from about 145 to about 185 C., preferably from about 150 C. to about 160 C. Because of the low levels of catalyst used in preferred embodiments, minimal or no off-flavors and little color are formed during the course of the reaction, but the product may be purified using ion exchange, membrane filtration, or carbon treatment, or further modified by hydrogenation if desired for certain applications.

Abstract: The present invention satisfies the long felt need in the beverage industry of a method of preparing tapioca starch balls that moves the time consuming, equipment demanding, and labor intensive process of precooking the dried tapioca starch balls to the tapioca starch ball manufacturer. The manufacturer precooks, freezes and conveniently packages the tapioca starch balls. The tapioca starch ball manufacturer will employ and train the personnel needed to precook the balls and not a retailer or a consumer. A retailer or a consumer will quickly and easily thaw or cook the conveniently sized preprocessed frozen packages of tapioca starch balls in a conventional microwave oven to prepare the balls for immediate use in Boba drinks. A retailer or a consumer can quickly react to sudden changes in demand for the balls by using the conveniently sized prepackaged frozen tapioca starch balls and thus reduce wasteful over production.

Abstract: Thermally-inhibited starches and flours which are functionally equivalent to chemically-crosslinked starches are prepared by a process which comprises the steps of dehydrating a granular starch or flour to anhydrous or substantially anhydrous (<1% moisture) and heat treating the dehydrated starch or flour for a time and at a temperature sufficient to inhibit the starch, (e.g., 120-180° C. for up to 20 hours). Preferably the pH of the starch is adjusted to neutral or greater (e.g., pH 8-9.5) prior to the dehydration. The dehydration may be a thermal dehydration carried out simultaneously with the heat treatment or a non-thermal dehydration carried out by extraction with a solvent (e.g., ethanol) or by freeze drying.

Abstract: Processes for extracting three sugars, fructose, sucrose and glucose, from dates are disclosed. Pitted dates are frozen and subdivided into particles. The particles are contacted with a heated water solution to extract the sugars from the date fibers. The sugar enriched water solution is separated from the date fibers by passing the water solution through one or more milli-screens. The sugar enriched water solution may be purified, and also may be treated to reduce the water content. The sugar solution containing the three sugars is a novel food product which can be used as a sweetener, for example, for sweetening soft drinks. Alternatively, the liquid product may be freeze-dried, vacuum oven-dried or spray-dried to produce a novel solid product containing the three sugars. The date fibers are dewatered, and admixed with ground date seeds to produce another novel food product.

Abstract: Method of producing oat extract from rolled oats and oat flour by performing a series of mixing, cooking, filtering and concentrating steps. The method comprises the steps of mixing rolled white oats with oat flour, bacterial or fungal enzymes, and water to form an oat/enzyme solution. The oat/enzyme solution is then mashed by cooking the solution to convert the starches present in the oats into sugars. The undissolved solids remaining from the rolled oats are separated from the oat mash by filtering the cooked oat mash using some of the undissolved solids as a filter bed. The filtering operation produces oat wort which is then concentrated to produce oat extract.

Abstract: A process for making a light color maple syrup from a water-containing sap. In a first step, the sap is boiled under normal pressure to evaporate part of the water contained therein in the form of steam, to form the maple syrup and to develop caramelized and sweet characteristics and give flavor and a tinted color to this maple syrup. In a second step, the sap is heated at a temperature lower than the boiling temperature of the sap and atomized through an air circulating column to evaporate another part of the water contained therein. This second step which can be carried out before the first one, permits to concentrate the sap, to increase its sugar content and to avoid further caramelization thereof. The sap which is so obtained with an increased sugar content, may be recycled as long as necessary until a desired sugar concentration corresponding to a predetermined Brix number is reached.

Abstract: Ammonia caramel color is formed in a fast cook method under elevated pressure and temperature by reacting ammonia catalyst with a carbohydrate syrup wherein the amount of water in the ammonia carbohydrate syrup mixture is controlled. The water content is maintained at preferably less than 40% of the mixture during a substantial portion of the caramelization reaction. Preferably the ammonia caramel is formed by reacting a carbohydrate syrup having a solids content of at least 75-80% with an anhydrous ammonia catalyst and reacting this at elevated temperature and super-atmospheric pressure over a period of 1-2 hours. Although the caramelization reaction generates water, the water content will not exceed 40%. This facilitates the rapid formation of caramel color without increasing the 4MeI or THI content, and without hazing of the caramel color. Further this produces a remarkably salt stable product.
