中文摘要:

非晶颗粒态淀粉是一种特殊的淀粉物态形式,具有颗粒性,但不具有结晶性,其具有较高的酶降解性、反应活性和吸附性能等。为了使非晶颗粒态淀粉工业化生产,对非晶淀粉颗粒进行了乙醇洗涤+常压烘箱干燥、真空烘箱干燥、常压烘箱干燥、真空冷冻干燥、喷雾干燥等不同干燥工艺。结果表明,不同的干燥工艺对非晶淀粉颗粒产生了不同的颗粒形貌。对其形貌的产生机理进行了科学的分析。

英文摘要:

As is a special starch modality,possessing granule quality but not crystalline,Non-crystal granular corn starch has preferable enzymatic degradation,reactivity and adsorption property.Bake-drying with washing with ethanol,vacuum bake-drying,atmospheric bake-drying,vacuum freeze-drying and spray-drying were applied to dry non-crystal granular corn starch for scale-up production.It showed that different drying technology affected morphology of non-crystal starch,which was analyzed scientifically.
