| 摘 要： | 本研究探讨了红花芸豆色素的最佳提取条件和色素的稳定性。实验表明最佳的提取工艺为:料液比1:75,提取温度60℃,提取时间90min。红花芸豆色素光、热稳定性好;在酸性条件下稳定,当pH≥4时出现混浊;对糖有一定稳定性;山梨酸钾、苯甲酸钠、柠檬酸对色素无不良影响;VC和H2O2对色素的稳定性有影响,色素对低浓度的VC较稳定。金属离子Na+、K+、Ca2+对色素无影响,而Fe3+、Cu2+、Fe2+、Zn2+、Mg2+对色素有明显影响。

| Abstract: | The optimal extractive process and stability of the pigment extracted from red speckled kidney bean (Phaseolus vulgaris L.) were studied. Results showed that the optimum extraction yield can be obtained by 75% acidic ethanol heated up at 60 ℃ for 90 minutes with a material-solvent ratio of 1:75(g/ml). The pigment holds good resistance to light and heat. Also, the pigment is stable in acidic conditions, but sediment emerges when pH is equal to or above 4. It is also resistant to carbohydrates. Potassium sorbate, sodium benzoate and citric acid have no adverse effects on the pigment but vitamin C and H2O2 do. The pigment is relatively stable with Vitamin C of lower concentration. Metallic ions Na+, K+ and Ca2+ have no effect on the pigment, but Fe3+, Cu2+, Fe2+, Zn2+ and Mg2+ have apparent effects on it. |
