为了制备黑米花色苷微囊,试验采用了冷冻干燥法,并以包封率为评价指标,采用响应面分析法优化黑米花色苷微囊的制备工艺。结果表明:壁材与芯材的比例为3.96,冷冻温度为-21.46℃,冷冻时间为11.9 min,真空度为79.56 k Pa时,得到的微胶囊粉末质地疏松,包封率达到62.54%。 In order to prepare the black rice anthocyanin microcapsules, the freeze-drying method was used in the experiment, and the encapsulation efficiency was used as the evaluation index to optimize the preparation process of black rice anthocyanin microcapsules by response surface analysis. The results showed that the ratio of wall material to core material was 3.96, the freezing temperature was -21.46 ℃, the freezing time was 11.9 min and the degree of vacuum was 79.56 kPa. The obtained microcapsule powder was loose in texture and the encapsulation efficiency reached 62.54%.
