【 摘 要 】

After pretreatment of micronization for 60 mins, the nanostarches were obtained by high speed jet (HSJ) of one cycle at 240 Mpa. The nanostarches were also observed by morphological analysis. Moreover, the zeta potential of nanostarches (-17 mv) dramatically decreased compared with native (-4.90 mv), and the pasting properties of nanostarches significantly changed, indicating the disruption of the crystalline structures. The obtained nanostarches were related to the breakdown of starch molecules. This study will provide useful information of the nanostarches for its potential industrial application.
