摘要:

为提高抗性淀粉的制备得率,以绿豆淀粉为材料,使用振动式超微粉碎技术处理绿豆淀粉,通过测定抗性淀粉含量,确定最佳超微粉碎时间为20 min;以微波糊化替代传统湿热糊化工艺,在单因素试验的基础上,采用Box-Behnken模型研究淀粉乳质量分数、微波功率、微波时间对抗性淀粉含量的影响,确定微波糊化提高抗性淀粉含量的最佳工艺条件为淀粉乳质量分数10.2%、微波功率670 W、微波时间4.3 min,此条件下抗性淀粉含量为32.80%,研究可为绿豆抗性淀粉的工业化生产提供理论依据。

Abstract:

To improve the content of resistant starch, mung bean starch was processed by vibrating superfine pulverization.
The optimum pulverization time was 20 min for increased resistant starch content. In this study, a microwave-assisted
procedure for starch gelatinization was employed instead of the conventional wet heat treatment. The effects of starch
concentration, microwave power and irradiation time on resistant starch yield were investigated by combined use of single
factor and Box-Behnken experimental designs. It showed that the optimum technological conditions for microwave gelatinization
were 670 W for 4.3 min at a starch concentration of 10.2%, and the yield of resistant starch was 32.80% under these conditions.
These results can provide an experimental basis for the industrial production of resistant starch from mung bean.

Key words: superfine grinding, microwave irradiation, mung bean starch, resistant starch
