摘要
研究得出从紫背天葵中提取天然紫红色素的最佳工艺条件是:以体积分数是30%的乙醇-水溶液作提取剂、温度为50℃、时间为2h、原料与提取剂配比为1g∶7mL,并研究影响紫背天葵紫红色素稳定性的因素。
The best conditions of extraction are: 30% alcohol as extraction solvent, material radio 1g:7mL, the temperature 50℃ and time 2 hours. The physicochemical properties of the pigment such as spectrum property, light stability, heat stability and the effect of pH, metal ions oxidant and reductant are also studied.
