摘要
以得率为指标,考察了降胭脂树橙色素提取条件。用正交分析得出最佳条件配比:料溶比1∶20,碱浓度0.6%,提取时间40min。
The extracting effects of annatto pigment are tested with rate of obtained pigment as standard. The optimum extracting condition is confirmed by orthogonal test： the ratio of simple and alkali solution is 1：20, alkali concentration is 0.6% and extracting time is 40min.
