    • Processes and products containing purified resistant starch with high resistant starch content. The processes include forming a water-starch suspension. The water-starch suspension is heated to temperatures above 100 DEG C and cooled to form a crude starch gel. The gel is comminuted and mixed with an amylase. The amylase digests non-resistant starch fractions leaving resistant starch. The amylase is inactivated, such as by heat treatment above 100 DEG C. Resistant starch is concentrated by washing and separating the non-solubilized resistant starch fraction, such as by centrifugation. Purification, such as with water and/or ethanol improves flavor, odor, and taste. The purified resistant starch products can be used as additives in novel food products to substitute for conventional dietary fiber sources, reduce caloric content, bind water, and absorb heat. Concentrated resistant starch can also be administered orally as powders, tablets, capsules, or caplets as a dietary supplement affecting gastrointestinal tract function.
    • 含有高抗性淀粉含量的纯化抗性淀粉的方法和产品。 该方法包括形成水 - 淀粉悬浮液。 将水 - 淀粉悬浮液加热至100℃以上并冷却,形成粗淀粉凝胶。 将凝胶粉碎并与淀粉酶混合。 淀粉酶消化残留抗性淀粉的抗性淀粉。 淀粉酶被灭活,例如通过在100℃以上的热处理。通过洗涤和分离未溶解的抗性淀粉部分,例如通过离心来浓缩抗性淀粉。 纯化,例如用水和/或乙醇改善风味,气味和味道。 纯化抗性淀粉产品可用作新型食品中的添加剂,以代替常规膳食纤维来源,降低热量,结合水分和吸收热量。 抗敏淀粉也可作为粉剂,片剂,胶囊或小珠片口服,作为影响胃肠道功能的膳食补充剂。
