玉米高压糊化淀粉的老化特性和变色性质

Ageing Behaviour and Colour Change of the Gelatinized Starch Processed by High Pressure(GSHP)

摘要: 研究了玉米淀粉高压糊化后的冻融稳定性和色泽变化，并和热糊化淀粉的老化特性和色泽变化做了比较。高压完全糊化淀粉糊没有与热加工糊化淀粉糊相同的老化现象。同时，高压不象热加工使玉米淀粉的颜色变黄。

Abstract: The stability of freeze after gelatinized and the colour change of GSHP were studied,these properties were compared with the gelatinized starch by heating (GSH).If the starch is entirely gelatinized under high pressure,there will be not ageing phenomenon of GSH. The colour of GSHP is not same as GSH,it does not change to yellow.
