摘　　要：本文研究了乌骨鸡黑色素提取工艺的操作条件以及光、碳水化合物、抗氧化剂、还原剂等因素对乌骨鸡黑色素稳定性的影响。结果表明,采用盐酸降解法,料液比为1:2,40℃条件下浸提3次效果最佳,提取率可达0.3736%。乌骨鸡黑色素对光和温度较敏感,防腐剂、碳水化合物对乌骨鸡黑色素的稳定有一定的影响,H2O2、Na2S2O3对乌骨鸡黑色素影响很小。In this paper, the extraction craft and the effects of sunlight,carbohydrate,H2O2 ,Na2S2O3 ,antiseptics on the stability of the melanin from white silky fowl was studied. The results showed that hydrochloric acid was used as the solvent and the optimum extraction condition was ratio of solid to liquid as 1 ： 2, at 40℃ and extraction three times. The extraction rate was 0. 3736%. The melanin is sensitive to light and temperature. The melanin is relatively stable to carbohydrates and antiseptics. H2O2 and Na2S2O3 have little influence on the melanin.
