中文摘要:
      采用搅拌球磨机对木薯淀粉进行机械活化,以蔗糖、麦芽糊精、蔗糖酯为分散剂和润湿剂,对机械活化淀粉进行修饰化处理。以结块重和透光率比值为评价指标,考察蔗糖、麦芽糊精、蔗糖酯添加量对机械活化淀粉分散性和润湿性的影响,结果表明,蔗糖、麦芽糊精、蔗糖酯都能提高机械活化淀粉的分散性;蔗糖、麦芽糊精提高产品的润湿性而蔗糖酯降低产品的润湿性。
英文摘要:
      Cassava starch was mechanically activated by a stirring ball mill, and then the activated starch was modified by using sucrose, maltodextrin and sucrose ester as dispersant and wetting agent. The effects of dosages of sucrose, maltodextrin and sucrose ester on the dispersion and wettability of activated starch were investigated by using caking weight and transmittance ratio as evaluation indices.The results showed that sucrose, maltodextrin and sucrose ester could increase the dispersion of products; sucrose and maltodextrin increased the wettability of the product, but sucrose ester decreased wettability.
