【摘要】 对荞麦皮粉中总黄酮的微波萃取工艺进行了研究。通过对微波辐射特性的初步研究,确定了微波功率的适用范围是200～800W。通过试验确定了萃取过程的最佳工艺条件为:微波功率500W,萃取时间7min,乙醇体积分数为60%,液料比为5,搅拌转速500r/min,在该工艺条件下总黄酮提取率为79.2%。更多还原

【Abstract】 The method of MAE in extracting flavonoids from the power of buckwheat was studied in this paper.At the pilot study,we confirm the effective range of action of microwave is 200 W to 800 W.And the single-factor experiment show the optimum technology with 500 W microwave power,7min extracting time,alcohol density of 60%,the ratio 5 between solvent and material,and stir-rate 500 r/min.Under these conditions,the actual output of flavonoids is 79.2%.更多还原
