摘要: 测定不同生长时期内的菠菜叶蛋白含量,以高蛋白含量生长期内的干菠菜叶作为实验材料,研究不同pH值、提取温度、提取时间及料液比对菠菜叶蛋白溶出率的影响。结果表明,pH值9.5、提取温度55℃、提取时间60min、料液比1:35为菠菜叶蛋白的最佳提取条件;pH4.0为菠菜叶蛋白的最佳沉淀pH值。

Abstract: The protein contents in different growth periods of the spinach leaves were assayed, and the dry spinach leaves of high protein contents during growth period were used as the raw material of this experiment.The effects of pH value,extracting temperature,extracting time and the ratio of water in extracting medium were studied. The results showed that pH9.5, extractingtemperature 45℃, extracting time 60min and the ratio of extracting medium to water 1:35 were the optimum extracting conditions of spinach leaf protein; while pH4.0 was the optimum precipitation pH value.
