摘要:

采用乙醇浸提法提取鸭血糯色素。选择浸提温度、乙醇体积分数、浸提时间、料液比及pH 值作为单因素进行梯度试验,确定其条件范围,再进一步通过正交试验确定鸭血糯色素提取的最佳工艺条件:浸提温度65℃、浸提剂乙醇体积分数75%、浸提时间3h、料液比1:110(g/mL)和pH1。

Abstract:

The optimal ethanol extraction of black sticky rice pigment was determined by examining the effects of extraction temperature and time, ethanol concentration, pH and material/liquid ratio on black sticky rice pigment yield (represented by the absorbance at 525 nm wavelength) by single factor and orthogonal array design methods. Results showed that the optimal values of the above parameters were as follows: extracting temperature 65 ℃, ethanol concentration 75%, material/liquid ratio 1:110 and pH 1 for an extraction duration of 3 h.

Key words: black sticky rice, pigment, extraction
