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 。
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.
