| Abstract: | Acid-hydrolysis and hydrolysate decolorized conditions for compound amino-acids production from duck feather are studied by using orthogonal tests. The experiment result shows that the optimum hydrolysis conditions are a ration of solid to liquid 1/3, a concentration of sulfuric acid 6mol/L, hydrolysising for 12h, compound amino-acids yield rate of 58%.The optimum hydrolysate decolorized conditions are decolorized temperature 80℃, carbon quantity 9%, decolourizing for 50min. |
