摘　　要： 针对豆渣蛋白含量高、产量大而未被充分开发利用的特点,研究采用木瓜蛋白酶酶解豆渣以制备锌螯合盐,从而实现提高大豆加工副产物豆渣资源的附加值。以豆渣为原料,通过单因素试验和正交试验,优化木瓜蛋白酶的酶解工艺条件,并研究豆渣酶解物与锌螯合制备多肽螯合盐的工艺。结果表明,木瓜蛋白酶最佳酶解条件为酶解温度50℃,酶解时间6 h,酶添加量0.04 g,豆渣添加量5 g,并以硫酸锌为锌源,得到的螯合率和螯合物中的锌含量分别为53.78%和40.00%。 Bean dregs protein content is high, large output without being fully exploited the characteristics of study papain bean dregs to prepare a zinc chelate salt, in order to achieve increase the added value of soybean byproducts bean dregs resources. The bean dregs as the raw material, through a single factor test and orthogonal test conditions papain enzyme and research bean dregs hydrolysates and polypeptides chelated zinc chelate salt preparation of process. The results show that papain optimum conditions for hydrolysis temperature 50 ~C, time 6 h, enzyme dosage 0.04 g, bean dregs quality 5 g, zinc sulfate and zinc source, chelating rate and chelate zinc content are obtained 53.78% and 40.00%.
