摘要
Abstract
[ Objective ] The technological conditions of preparing food additive sodium pulyacrylate were discussed. [ Method ] Using ( NH4 ) 2 S2 O8-NaHSO3 as mixed initiator, the influences of monomer concentration, dosage of initiator components, reaction temperature, reaction time on the relative molecular mass of sodium pelyacrylate were studied by using aqueous solution polymerization method. [ Result ] The optimum technological conditions of sodium polyacrylate were as follows: the reaction temperature of 40 - 45 ℃, the reaction time of 4 h,( NH4 ) 2 S2 O8 dosage of 0.02％, NaHSO3 dosage of O. 01％, the monomer concentration of 45％. Under these conditions, the molecular mass of sodium polyacrylate was 30 000 000 ～ 35 000 000. [ Conclusion ] Through the detection, the prepared sodium polyacrylate can meet the requirements of food additive. It played good thickening and fresh-keeping effects when it was used in some kinds of food.关键词
