摘要
采用碱溶酸沉原理,通过单因素实验和正交实验,确定了杏仁分离蛋白一次碱提最佳工艺条件为:固液比1∶30,pH值8.5、温度50℃、时间70 min,对一次提取残渣进行二次提取后,最终蛋白质提取率可达84.3%,蛋白质含量为63.2%。
This paper adopted the theory of solubization and acid precipitation to determine the optimum conditions of first alkaline extraction about almond separated protein： the ratio of solid to liquid 1 ： 30,the extraction pH 8.5,the temperature of extraction 50 ℃ and the extraction time 70 min are obtained by both single factor experiment and orthogonal expreriment to further extract the residue. At last the maximum of extracting ratio is 84.3 %, and protein evel is 63.2%.
