| 摘 要： | 以黑米为原料，优化黑色素的最佳超声辅助提取工艺。采用正交试验法，研究超声波功率、浸提时间、浸提剂体积分数及料液比(黑米︰乙醇溶液，m/V)对黑米色素提取率的影响。结果表明：在所考察的因素中，黑米黑色素的最佳提取工艺为A3B1C3D3。浸提黑色素宜选体积分数80% 的乙醇溶液作为提取剂，超声波作用时间50min，料液比1:32，超声功率250W，该优化方法的提取率为4.5%，比传统的索式提取法的提取率提高了近3 倍。

| Abstract: | Ethanol was used for extracting black rice pigment under ultrasound assistance.To maximize the extraction of black rice pigment,orthogonal array design was employed for investigating the effects of ethanol concentration,solid-to-liquid ratio,ultrasound power,extraction time on black rice pigment yield (represented by the absorbance at 543 nm wavelength of extract solution).Results showed that the use of 80% ethanol for extracting black rice grains at 1:32 solid-to-liquid ratio (m/V) with the assistance of 5... |
