摘要: 本研究以鹰嘴豆为原料,研究了缓冲液种类、缓冲液pH值、料液比、盐析盐种类、盐浓度等因素对鹰嘴豆铁蛋白提取率、总蛋白提取率及干重的影响。在单因素实验的基础上,以L9(34)正交实验方法优化鹰嘴豆铁蛋白提取工艺。结果表明:各因素对鹰嘴豆铁蛋白提取率的影响顺序依次为:料液比>盐浓度>温度>pH。最优提取工艺为:料液比1:4,浓度为70 mmol/L MgCl2盐析,温度50 ℃,KH2PO4-NaOH缓冲液pH 7.5,最优提取率为0.002643%。

Abstract: Chickpea seeds were widely used as raw material to extract ferritin.To maximize the extraction yield of ferritin,extraction parameters,including buffer types,buffer pH,solidliquid ratio,type and concentration of salt were investigated by single factor experim-ents followed by four factorthree level orthogonal experiments.The extraction yield of ferritin,total protein and dry weight in chickpea seeds were examined.The results showed that the effect of the investigated factors on the extraction yield of chickpea ferritin was in sequence of solidliquid ratio > salt concentration > temperature > pH.The optimal extraction condition was as follows:solid-liquid ratio 1:4, 70 mmol/L MgCl2,extraction temperature 50 oC, KH2PO4-NaOH buffer solution at pH 7.5.The optimal extraction yield was 0.002643%.
