Abstract
Comparative study on extraction process of Taihe silky fowl melanin(SF-M) with enzymatic and hydrochloric acid methods. The optimum extraction conditions of SF-M were determined by single-factor experiments and orthogonal tests of enzymatic and hydrochloric acid methods,besides,anti-free radical properties, light and heat stabilities of SF-M from two extraction methods were studied and compared. The results showed that the optimum extraction condition of SF-M with enzymatic method was obtained as follows; the use of papain, pH 6.0,temperature 65℃, the ratio of material to liquid 1:2(m:V),the ratio of enzyme to substrate 1:25(m:m) for 4 hours; the optimum extraction condition of SF-M with hydrochloric acid method was the ratio of meal to liquid 1:4(m:V), reflux temperature 95℃ . extraction time 2 hours; the extraction ratio of SF-M with enzymatic extraction was higher than the hydrochloric acid extraction, the anti-free radical properties and the heat stability of SF-M with enzymatic extraction were better than the hydrochloric acid extraction. It illustrated that the enzymatic extraction method was better than hydrochloric acid extraction melhod.关键词
