碱性角蛋白酶用于兔皮脱毛的研究

The Research for Application of Alkaline Keratinase for the Unhairing of Rabbit Skin

采用碱性角蛋白酶堆置脱毛法对兔皮进行脱毛处理,对脱毛工艺的酶用量、石灰用量、温度等条件进行了优化,得出了最佳的堆置酶脱毛方案。同时对经不同情况处理的毛进行了扫描电镜和强度测试,探究该方法对兔毛质量的影响。实验结果表明,酶用量为皮重的0.05%～0.09%、温度为32℃、时间在4 h时堆置酶脱毛,可以有效除去兔皮上的兔毛,并且对脱下的兔毛质量损伤较小,该脱毛工艺可以有效回收兔毛,为兔毛和兔皮的深加工提供原材料。

Piled alkaline keratinase unhairing method is used on rabbit skin in this article. The dosage of keratinase, dosage of lime and temperature are optimized. The best processing parameters for rabbit skin unhairing are obtained. At the same time, the rabbit hair treated with lime and enzymes are analyzed with SEM and DSC, in order to determine the effect of enzyme unbairing on hair. The results show that, the hair of rabbit can be effectively removed in 4 h, when the dosage of enzyme is 0.05%-0.09%, temperature is 32℃, with a little damage to the removed hair.
