摘要
对乳清小肽粉的表观密度大小与溶解冲调性的关系进行了研究。密度在0.3519～0.3785g·cm-3的粉粒,溶解冲调性最好。研究了料液浓度、进风量、进口温度对干燥粉末的影响,并采用响应面分析法(RSD)优化了微胶囊化乳清小肽喷雾干燥的工艺参数。实验结果表明,喷雾干燥的最佳条件为:料液浓度27.75%、进风量3.72m3/min、进风温度190℃。
The dissolving ability of the microencapsulated whey small peptides and spray drying conditions were studied.The results showed that when the apparent density was between 0.3519g·cm-3 and 0.3785g·cm-3,the dissolving ability of the microencapsulated small whey peptides was the best,through Box-Behnken experimental response surface design（RSD）,the spray drying optimization conditions were reactant concentration 27.75%,intake air volume 3.72m3/min and temperature of entering air 190℃.
