| 摘 要： | 通过对甘谷辣椒红色素进行提取,确定了其中的4种成分,研究了色素提取的最佳条件及色素的稳定性.结果表明:该色素含有辣椒红色素、辣椒玉红素、β-胡萝卜素、辣椒碱、二氢辣椒碱5种主要成分.色素在480 nm有最大吸收峰,该色素水溶性较差,油溶性较好,在pH值4~10时色调不变,具有良好的热稳定性.温度为90℃时,色素稳定.良好的耐酸碱性,耐光性较差,连续光照48 h,色素残存率为45%,1 mg/L Na+,Ca2+、Al3+溶液对色素最大吸收峰无明显影响,1 mg/L Cu2+,Fe2+溶液使色素最大吸收峰偏移.

| Abstract: | The stability of capsicum was studied.Results showed that this capsicum pigment has absorption peak in visible spectrum,exists in 480nm.The pigment is!not dissoluted in water but dissoluted in organic solvent.The pigment is very stable in the condition of pH 4～10 and temperature 90 ℃.The lighting for 48 h renders its degradation and the degradation rate is 45%.Na~+,Ca~(2+)and Al~(3+) have no effect on absorption peak,but Cu~(2+) and Fe~(2+) hawe effect on absorption peak. |
