Research On Ultrasonic Assisted Extraction Of Mung Bean Skin Of Flavone Extract And Its Application

This thesis with mung bean peel as main experimental material, mung bean skin is rubbed down in bubble hair bean seed coat, with a skin dried obtained, also called mung bean shell. Mung bean in China Chinese medicine called mung bean, the effect of clearing away heat and mung bean is stronger than itself. Mung bean is mainly heat, green bean is mainly the role of detoxification.The study found that, among the most active ingredients of mung bean, mung bean skin are in, such as flavonoids, tannins, saponins etc.. It also contains alkaloids, stigmasterol, coumarins, cardiac glycosides, and the amount of dietary fiber. In this paper by ultrasonic extraction flavonoids from mungbean skin, and the liquid added in skim milk by lactic acid fermentation of Extracting Flavonoids from mungbean skin, has developed a certain effect of mung bean peel flavonoids yogurt.Bark of green beans various factors single factor test conditions, orthogonal test analysis.Test results are as follows:Mung bean skin flavonoids affect primary and secondary factorssolid-liquid ratio> ethanol concentration> ultrasonic temperature>ultrasonic time; optimum A2B2C3D1, namely: liquid ratio of 1:30,70% ethanol, ultrasonic time 9min, ultrasonic temperature 60 ℃;Mung bean yogurt for skin conditions formulated to various factorssingle factor experiment, orthogonal experiment,.The test results were as follows:Effect of mung bean skin flavonoids yogurt primary and secondary factors: the amount of emulsion> White sugar amount> strainamount> the amount of flavonoids extract; optimumA2B3C2D2,namely: mung bean skin flavonoids extract 30%, the amount of lactic acid bacteria inoculation 3.5% emulsion dosage 60%, 7% sugarsugar dosage.
