| Abstract: | Basic on a comparative experiment,study the decolorization process of protein from silkworm chrysalis by using alkaline H2O2.In the study based on single factor,regarding Hunter whiteness of study indicators,study how treatment temperature,H2O2 concentration,processing time,pH,solid-to-liquid ratio affect the decolorization of pupa protein,by orthogonal test optimizing decoloration process.The results indicated that the best decolorization process of protein from silkworm chrysalis were as follows:treatment temperature 75℃,H2O2 concentration 14%,processing time 70min,pH 8.5,solid-to-liquid ratio 1∶ 25.Under this condition,Hunter whiteness can reach 63.96%. |
