木瓜蛋白酶的提取（Extraction of Papain） Papain extraction.Txt as long as you want, as long as I have, you still turn around what ah, honest, stay with me on the line. Listen to me, ask why so much, I am on your side, you can go wrong! Follow me! I cant give you happiness is my fault, but who you are not happy, I TMD to cut his extraction and purification of Papain Preface： Papain (Papain), also known as papain, is widely found in the stems, leaves and fruits of papaya, and is the highest in the milk of immature fruit. It is a proteolytic strong catalytic activity and containing curds and bacteriolytic activity, also has the ability of lipolysis and protein synthesis function, is the main catalytic hydrolysis of proteins, small peptides can also break down. It is cutting down a lot, generally preferred decomposition of arginine and phenylalanine peptide enzyme. Because of its high content, good stability, can effectively decompose gelatin, casein, gluten, elastic protein, globulin and muscle fiber protein protein, is widely used in meat tenderization, beer clarification, gelatin production, cocoon degumming, hair removal and other leather industry, the other is medicine used in the treatment of dyspepsia and all kinds of inflammation and edema, prevent peritoneal adhesions, blood examination and treatment exuvial trauma; in addition, it can also be used for the study of protein structure and so on. Papaya contains papain in the stems and leaves, but in the actual production, mainly composed of papaya fruits mature in peel out of the wound never collected white slurry, obtained after processing after purification. Papain production in papaya immature fruit fresh milk as raw material, but because the planting area is mainly distributed in papaya economically underdeveloped areas, so the protease production process is relatively backward, many areas are still produced by papain sun exposure mode. In addition, for papain commercial production, considerable differences exist in th
