【摘要】 本文对青葙红色素的提取条件及稳定性进行了研究。结果表明 :提取最佳条件以pH =3体积分数 70 %的乙醇为提取剂 ,物料比 1g∶2 0mL ,在 35℃下浸提 4h ,青葙花红色素对光、热稳定性较差 ,抗氧化性较好 ,在酸性介质中稳定更多还原

【Abstract】 The studies have been prefermed on the extracting conditions and stability of red pigment from Celosia argenteal. The result showed that the best optimum conditions were the extraction reagent 70% alcohol with pH 3, the ratio of the solid material to solution 1 g∶20 mL, the extraction temperature at 35℃ for 4 hours.It has better stability to oxidizer,acid ect.However,it has less stability to sunlight and heat.更多还原
