摘 要: | 研究了微波辅助碱法降解黄曲霉毒素B1(AFB1)优化工艺对米蛋白品质的影响。研究表明,在单位体积微波功率750 W/L条件下,随着微波处理时间(0.2、3.1、5.6、7.2和8.6 min)的延长,微波辅助碱法制备无毒米蛋白的回收率及纯度的变化不显著,溶解性、起泡性和持油性显著提高,起泡稳定性、乳化性及乳化稳定性先提高后下降,而持水性呈下降趋势。因此,该工艺不仅能确保米蛋白产品安全无毒,还可提高米蛋白的部分品质。

Effect of aflatoxin B1 degradation by microwave-assisted alkali treatment on the quality of no-toxic rice protein |
| |
Abstract: | Based on the optimized process of aflatoxin B1(AFB1) degradation by the microwave-assisted-alkali treatment, the quality of non-toxic rice protein was evaluated with the microwave treating time accumulating. The experimental results showed that on the one hand, the effect of microwave-assisted on the recovery and purity of rice protein was not significant, and the properties of solubility, foamability, oil retention and in-vitro digestibility improved significantly; on the other hand, the properties of foaming stability, emulsification and emulsifying stability improved first and then decreased, while the water retention decreased. Thus, the process not only makes rice protein free of aflatoxin, but also improves its quality of parts. |
