中文摘要: 为提高苦杏仁粕谷蛋白溶解性,采用糖基化方法改性修饰。该试验选用葡萄糖进行接枝改性,考察反应温度、反应时间、pH值、蛋白与糖质量比对葡萄糖改性蛋白溶解度的影响。在单因素试验的基础上,通过Box-Behnken响应面法确定葡萄糖改性蛋白的制备工艺。结果表明,优化后工艺条件为反应温度63℃、反应时间0.6 h、pH 9.4、蛋白与糖质量比1∶2。在此条件下,葡萄糖改性蛋白溶解度为96.24%。
Abstract:To improve solubility of gluten from bitter apricot kernel meal,a method was developed to glycosylate gluten.The effects of reaction temperature,reaction time,pH and protein-sugar mass ratio on the solubility of glucose modified protein were investigated.Box-Behnken response surface methodology based on single factor testing was used to optimize a preparation process for glucose modified protein.The optimal process conditions were as follows:reaction temperature 63 ℃,reaction time 0.6 h,pH 9.4,protein-sugar mass ratio 1∶2.Under these conditions,glucose modified protein solubility was 96.24%.
