摘要: 本实验将越桔天然色素纯化后测定其光谱特性,并研究了温度、光照、pH值对越桔色素稳定性的影响及色素的耐氧化还原性。着重研究了食品添加剂对提高越桔色素稳定性的作用,选取其中四种有较强提高稳定性作用的食品添加剂进行了正交试验,确定了最佳方案。从实验所得:最优水平组合为丁二酸0.09%、阿魏酸0.03%、对羟基苯甲酸0.08%、柚皮苷0.01%。

Abstract: In this experiment, the natural pigment of Vaccinium vitis-idaea linn has been purified, and its spectrum characterisicdetermination was described afterward. The effects caused by temperature, illumination and pH on the stability of Vacciniumvitis-idaea linn pigment and the reducing quality of the pigment have been studied. Food addiitives added into as enhancers, havebeen studied emphatically. Orthogonal experimental design was put up with four food addiitives having better stabilizingeffect. The optimum stable conditions were : the concentration of succinic acid, trans-ferulic acid, para-hydroxybenzoic acidand naringin was respectively 0.09%, 0.03%, 0.08% and 0.01%.

Key words: Vaccinum vitis-idaea linn, natural pigment, stability, orthogonal experimental design
