四翅滨藜叶蛋白提取工艺优化及氨基酸分析

Multi-user joint detection in TD-SCDMA

对四翅滨藜叶蛋白的提取工艺及氨基酸分析进行研究,确定最佳工艺条件为:料液比1∶20,预浸48 h,打浆时间4 min,pH=3.0,60℃条件下絮凝5 min.此时叶蛋白提取率和收率分别可达31.05%和1.12%.氨基酸分析结果显示,四翅滨藜叶蛋白的氨基酸组成种类齐全,必需氨基酸含量较高,氨基酸分数较高,是一类比较优质的蛋白质资源.

The extraction techniques and amino acid of leaf protein from Atyiplex Canescen were studied. The optimization conditions were quality ratio 1 ： 20, soak time 48 h, pulping time 4 min, pH = 3.0, flocculation 5 min at 60 ℃ ,on such conditons the percent of extraction and yield of leaf protein were 31.05% and 1.12% respectively. The results showed that leaf protein from Atyiplex Canescen contained relatively complete amino acid composition and was rich in essential amino acids. It is a kind of valuable protein resource.
