由复合氨基化合物合成高色率焦糖色素的工艺研究

Study of Synthesis of Caramel Pigment with High Color Ratio by Using Complex Amido Compounds

采用复合氨基化合物作反应剂与葡萄糖废母液进行美拉德反应,在高温高压下进行液体焦糖色素的合成研究。考察了反应温度、反应压力、反应时间及复合氨基化合物用量等因素对焦糖色素色率值的影响,得出以下最佳合成条件:反应温度150℃,反应压力0 7MPa,反应时间0 5h,w(复合氨基化合物)=5 5%(相对于反应物总质量)。按该条件合成的焦糖色素色率值高达95132EBC单位,反应时间大大缩短,各项质量指标完全符合GB8817—2001要求。

Liquid caramel pigment with high color ratio is synthesized by Maillard reaction under high temperature and high pressure,using complex amino compounds as reagent and waste mother liquor from glucose production as raw material.The optimum technological conditions are reaction temperature 150 ℃,reaction pressure 0.7 MPa,reaction time 0.5 h and w(complex amino compounds)=5.5%(based on total reactants). The color ratio of caramel pigment synthesized is 95132 EBC and the product quality is in accord with the standard of GB8817—2001.
