摘要
针对栀子黄色素在使用中不稳定的问题,通过加入复合食品添加剂的方法,提高其稳定性.以药用栀子果实为原料,提取栀子黄色素,考察了海藻酸钠等12种食品添加剂及7种不同复合添加剂对其稳定性的影响,从而确定出最佳食品添加剂及复合食品添加剂.研究发现:单一海藻酸钠和甲酸钠比文献报道的EDTA-Na2更能稳定栀子黄色素的分子结构;复合食品添加剂海藻酸钠+甲酸钠的组合对该色素的稳定效果更佳;加入复合食品添加剂海藻酸钠+酒石酸钠+甲酸钠的色素溶液是所有样品中稳定性最好的.
This paper used the method of adding composite food additives,firstly,in order to improve the stability of gardenia yellow pigment.In this study,the author used the gardenia fruit used in medicine as the studied material to extract gardenia yellow pigment.It studied the effects of twelve kinds of food additives and seven kinds of composite food additives on the stability of gardenia yellow pigment and confirmed the optimal food additives and composite food additives.The results showed that singel alginate a...
