Disclosed is method for preparation of a starch phosphate using phytate. The method enables the preparation of a starch phosphate with improved physical properties such as high transparency, solubility, swelling power, and storage stability by the phosphorylation of a starch using naturally occurring phytate rather than using a synthetic chemical. Due to these advantages, the starch phosphate is expected to replace conventional chemically modified starches. In addition, the method enables the preparation of a starch phosphate based on a simple modification. The use of the starch phosphate greatly contributes to improvements in the quality and storage stability of various starchy foods. Therefore, the starch phosphate is expected to find application in the food industry, including starchy foods.

The present invention provides a method of producing phosphoric acid crosslinked starch, including adding phosphorus oxychloride sequentially to raw starch slurry under a condition of pH 9 to 12 to cause the raw starch to undergo a phosphoric acid crosslinking reaction, and controlling the pH by sequentially adding an alkaline solution, wherein concentration of the alkaline solution is increased stepwise or continuously between start and end of the phosphoric acid crosslinking reaction. By the production method of the present invention, phosphoric acid crosslinked starch having a low phosphorus content and a high resistant starch content (for example, pea-derived phosphoric acid crosslinked starch, which has a resistant starch content of 80% or more according to a resistant starch measurement method of AOAC official method 2002.02 and a phosphorus content of 0.5% or less) can be obtained.

Modified biopolymers, such as, charge-modified biopolymers, cross-linked biopolymers, and cross-linked, charge-modified biopolymers are provided along with methods of producing and using the same.

The present invention provides a starch with high dietary fiber content that does not deteriorate texture or flavor when added to a food. Provided is a phosphoric acid crosslinked starch obtained by subjecting a starting starch material to a phosphoric acid crosslinking treatment, wherein: when suspended in water to give a concentration of 7% by weight on the anhydrous basis, the starting starch material shows a gelatinization starting temperature of 80 C. or lower; in the phosphoric acid crosslinked starch, 70% by volume or more of particles have a particle diameter of 18-35 m; and the content of dietary fiber in the phosphoric acid crosslinked starch is 50% by weight or greater. The phosphoric acid crosslinked starch according to the present invention is useful in manufacturing compositions for dietary fiber enrichment, foods for restricting carbohydrate intake or low calorie foods.

This invention pertains to low swelling starches and their use as food texture modifiers. The invention further pertains to the method of using low swelling starches as fat substitutes in foods. The low swelling starches provide opacity, mouth-coating, and creaminess to foods.

A low protein yogurt composition is provided comprising water, at least one dairy ingredient and a crosslinked waxy starch, wherein the crosslinked waxy starch is crosslinked with phosphate groups and has a peak Brabender viscosity of from about 600 to about 1500 Brabender units, and the cross-linked waxy starch is present in an amount sufficient to add viscosity to the yogurt. The crosslinked waxy starch can also be stabilized by acetylation to obtain longer shelf life.
