以云南樱花为材料,通过其溶解性、不同pH值下的颜色变化和最大吸收波长进行了初步定性,通过提取次数、提取时间、液料比和提取温度进行了提取工艺的研究。结果表明:云南樱花色素为一种甜菜素,包括甜菜红素和甜菜黄素;该色素的提取工艺参数为:提取次数3次,提取时间40 min,料液比1∶10(g∶mL),提取温度30℃。

The qualities and extraction technology of Prunus cerasoides pigments were studied by the comparison of the pigment solubility in different solvents,colors changes in different pH and the maximum absorptions.Various factors that affected the extraction technology of the pigment were investigated including extraction times,extraction time,ratio of material to liquor and extraction temperature.Results showed the pigment was one of the betalains and contained betacyanin and betaxanthin.The best extraction technology was: three times extraction for 40min under 30 ℃ and ratio of material to liquor was 1∶10(g∶mL).
