  • Publication number: 20210112833
    Abstract: Described herein is a method of manufacturing a soluble flour comprising preparing a flour-water slurry, adjusting the pH of the slurry to a pH ranging from 3.5-6, adding an enzyme to the pH adjusted slurry in an amount ranging from 0.02-2.0 g enzyme/g flour to form a reaction mixture, cooking the reaction mixture at a temperature ranging from 60-140 C until a dextrose equivalent of 5 to 18 is achieved, inactivating enzyme to obtain a soluble flour; and adjusting pH of the soluble flour to range from 4-5. The soluble flour obtained has a dextrose equivalent value ranging from 5 to 18, a solubility greater than 50% (at 5% solids), and a viscosity between 0.001 and 1.0 Pa* at temperatures ranging from 20-50 C (at 10% solids).

  • Publication number: 20090011082
    Abstract: 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.

  • Publication number: 20060257977
    Abstract: 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.
