Thermally-inhibited non-pregelatinized granular starches and flours and process for their preparation

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 (

Abstract(Chinese):

在功能上等同于化学交联淀粉的热抑制淀粉和面粉通过包括以下步骤的方法制备，所述方法包括以下步骤：将颗粒状淀粉或面粉脱水至无水或基本无水（<1％水分）并热处理脱水淀粉或面粉一段时间并且足以抑制淀粉的温度（例如，120-180℃长达20小时）。优选地，在脱水之前将淀粉的pH调节至中性或更高（例如，pH 8-9.5）。脱水可以是与热处理同时进行的热脱水或通过用溶剂（例如乙醇）萃取或通过冷冻干燥进行的非热脱水。
