摘要:
研究了超高压辅助酶法脱除黄曲霉毒素B1优化工艺对米糠多肽品质的影响。研究表明,在超高压300MPa条件下,随着超高压处理时间(0、1、3、5、7、9min)的延长,超高压辅助酶法制备无毒米糠多肽的多肽得率、水解度、溶解性、起泡稳定性、乳化性和乳化稳定性先提高后下降,起泡性和持油性显著提高,而持水性呈下降趋势。因此,该工艺不仅能确保米糠多肽产品安全无毒,还可提高米糠多肽的品质。

Abstract:
Based on the optimized process for aflatoxin B1(AFB1)removal through the ultra high pressure-assisted enzyme treatment, the quality of rice bran polypeptides has been evaluated. Under the ultra high pressure of 300MPa, the yield, degree of hydrolysis, solubility, foaming stability, emulsification and emulsifying stability of polypeptides increased first and then decrease when the treatment time increased from 0 to 9min. The foamability and oil retention of polypeptides significantly improved while the water retention decreased. The process could remove aflatoxin from rice bran polypeptides and improve the quality of rice bran.
