Publication number: 20090011082Abstract: A process for producing a starch comprises treating a feed starch that comprises amylopectin with glucanotransferase to produce a chain-extended starch, and treating the chain-extended starch with a debranching enzyme to produce a starch product that comprises amylose fragments. In certain embodiments, the process further comprises, crystallizing at least part of the starch product, heating the starch product in the presence of moisture, treating the starch product with alpha-amylase, and washing the starch product to remove at least some non-crystallized starch, wherein the degree of polymerization of the starch product is increased by increasing the amylose content of the feed starch or is decreased by decreasing the amylose content of the feed starch. The product of this process can have a relatively high total dietary fiber content, a relatively high heat resistance, or both.Type: ApplicationFiled: March 6, 2008Publication date: January 8, 2009Inventors: Donald W.

Publication number: 20060257977Abstract: The invention provides processes to make slowly digestible starches from native and commercial starches. Slowly digestible starches are prepared by controlled hydrolysis of gelatinized starch by alpha amylase. The slowly digestible starches have a range of starch digestion rates and fall between normal, untreated commercial and native starch, and commercial resistant starches. The slowly digestible starches provide a range of starch functionalities. These slow digesting starches retain their digestion characteristic after cooling, and can used in a range of processed food products to modulate the rapid glucose release typical of many processed starchy foods. Edible products incorporating slowly digestible starch will exhibit lower glycemic index and increase satiety. The invention provides solid and liquid food, nutritional, and drug preparations containing the slowly digestible starch.Type: ApplicationFiled: January 28, 2004Publication date: November 16, 2006Inventors: Bruce Hamaker, Xian-Zhong Han
