【摘要】 大豆肽本身具有抗氧化作用,经过一定条件的超滤膜处理后,大豆肽的抗氧化作用得到了显著提高。通过实验表明,抗氧化作用的肽是分子量小于2000Da的组分,并且利用响应面法优化了2000Da的超滤膜,超滤的最适条件为超滤压力0.37MPa、pH6、温度44℃、时间100min。在此超滤条件下的响应面分析预测值为29.09912L/(m2.h),并且通过验证实验得以验证。更多还原

【Abstract】 Soybean peptide has the effect of anti-oxidation.After being processed by ultra-filtration film on certain conditions,the anti-oxidative effect of soybean peptide can be improved significantly.The experiment showed that the peptide,which causes the anti-oxidation,was the component whose molecular weight is less than 2000Da.In the experiment the method of response surface had been applied to improve the ultra-filtrate film with 2000Da,and the best appropriate ultra-filtrate condition was that:ultra-filtration pressure 0.37MPa,pH value 6,the temperature 44℃,the time 100min.The analytical predictor of response surface under this ultra-filtration condition was 29.09912L/(m2·h),which had been verified in verification test.更多还原
