摘　　要：为有效脱除驴肉及内脏酶解液中的镉,文章首先研究了蛋白酶酶解驴肉、驴肝脏、驴肾脏3种酶解液的制备工艺;分析料液比、加酶量、酶解时间对酶解工艺的影响,并利用正交实验确定了最佳的酶解条件。随后考察D403大孔螯合树脂和DK110大孔弱酸阳树脂脱除驴肉、驴肝脏、驴肾脏3种酶解液中镉的条件,分析树脂用量、反应p H值、反应温度以及反应时间对镉脱除的影响,并得到了最佳工艺条件。结果表明,2种树脂对酶解液中重金属镉离子的脱除均表现出很好的效果,不同的酶解液要根据实际情况确定不同的树脂脱除条件,以便更好地节约成本、提高脱除效率。In order to effectively remove cadmium from donkey meat and visceral enzymatic hydrolysate,this paper first studied the preparation process of three enzymatic hydrolysates:donkey meat,donkey liver,and donkey kidney,analyzed the effects of feed to liquid ratio,enzyme dosage,and enzymatic hydrolysis time on the enzymatic hydrolysis process,and determined the optimal enzymatic hydrolysis conditions using orthogonal experiments.Subsequently,the conditions for removing cadmium from donkey meat,donkey liver,and donkey kidney hydrolysate using D403 macroporous chelating resin and DK110 macroporous weakly acidic cation resin were investigated.The effects of resin dosage,reaction pH,reaction temperature,and reaction time on cadmium removal were analyzed,and the optimal process conditions were obtained.The results showed that both resins exhibited good performance in removing heavy metal cadmium ions from enzymatic hydrolysis solutions.Different resin removal conditions should be determined according to the actual situation for different enzymatic hydrolysis solutions in order to better save costs and improve removal efficiency.
