摘要: 采用水酶法从花生中提取蛋白质,筛选了三种酶制剂,确定选用纤维素酶作为水解酶;得出纤维素酶提取花生蛋白的最佳条件为:碱浸提液pH7.5,浸提温度45℃,酶用量0.2g/L,反应时间120min,酸沉pH4.5;在此条件下花生蛋白的得率为69.59%,蛋白质含量为91.88%。

Abstract: The aqueous enzymatic process of peanut protein from peanut was introduced in this paper. The cellulase was adopted. The optimum process conditions with cellulose were as followalkaline extraction of pH 8.5,temperature 45℃,amount of enzyme added 0.2g/L,enzyme reaction time 120min,acid precipitation of pH4.5. On these conditions,the product yield of peanut protein reached 69.59%,the content of peanut protein was 91.88%.
Key words: aqueous enzymatic extraction, peanut protein
