摘要
[目的]探索酸藤子果实红色素的微波辅助提取工艺条件。[方法]采取微波法提取酸藤子果皮红色素,通过单因素试验、正交试验、提取级数试验对其工艺条件进行优选。[结果]微波法提取酸藤子果皮红色素的优化工艺条件为:以原料70倍量的pH值3.0柠檬酸磷酸盐缓冲液,在微波功率450 W的条件下提取180 s,提取级数为2次。该条件下,色素提取率达90.46%,果皮总花色苷得率为50.66 mg/100 g。[结论]微波法是一种高效的、节约成本的酸藤子果皮红色素提取方法。
[ Objective ] The study aimed to explore the microwave-assisted extraction technics of red pigment from Embelia laeta pulp. [ Method ] The red pigment of Embelia laeta pulp was extracted by the microwave-assisted extraction. And its optimum conditions were found by the single factor experiment,orthogonal test and extraction times experiment. [ Result ] The optimum extraction conditions of microwave-assisted extraction were as follows： the ratio of material to citrate phosphate buffer extractant （pH 3.0）was 1：70, microwave power was 450 wattage, microwave treat- ment time was 180 seconds, extracting times was 2 times. Under these conditions, the extraction rate of pigment reached 90. 46%, and the yield rate of total anthoeyanin from the pulp was up to 50.66 mg/100 g. [ Conclusion ] The microwave-assisted extraction is a more effective and economical method to extract red pigment from Embelia laeta pulp.
