Research on Pretreatment Technology for Corn Husk Degumming

Abstract

In this study, chemical degumming was applied to corn husks, and the optimal degumming procedure and pretreatment method were determined. Through orthogonal experiments, it was determined the optimal pretreatment parameters are: H₂O₂ concentration of 8 g/L, urea concentration of 8 g/L, pretreatment temperature of 20 °C and pretreatment time of 30 min. The effectiveness of this combination of parameters was validated by its resultant glial removal rate of 85.32%.
