摘要: 选用磷酸二氢钠作酯化剂制备玉米磷酸酯淀粉,研究了酯化剂用量、反应温度、反应时间对磷酸酯淀粉的抗老化特性和粘度的影响。结果表明,随着酯化剂用量的增大、反应温度的升高、反应时间的延长,其抗老化特性增强,粘度减小,其最佳工艺参数为:酯化剂用量5%;反应温度130℃:反应时间4h。所得磷酸酯淀粉应用于姜膏生产,可获得良好的组织状态。

Abstract: Factors affecting the anti-retrogradation and viscosity of corn starch phosphate with NaH2PO4 esterification were studied.The results showed that the anti-retrogradation increases and the viscosity decreases with the levels of esterification, reaction temperature and reaction time.The optimal conditions for corn starch phosphate preparation are:amounts of NaH2PO4, 5%,reaction temperature 130℃,and reaction time 4h.The phosphate corn starch can be used in ginger paste and bring in good texture.

Key words: phosphate starch, starch, ginger paste
