木瓜蛋白酶酶解米渣制备氨基酸蛋白饮料

Preparing Amino Acid-Protein Beverage from Rice Residue by Papain Enzymolysis

以味精厂下脚料的米渣为原料 ,利用木瓜蛋白酶对米渣进行水解。通过正交试验和验证试验确定酶解米渣蛋白的最适条件。利用其酶解液可配制成氨基酸蛋白饮料。氨基酸蛋白饮料中含蛋白质为 182 .35mg/ 10 0ml,8种必须氨基酸含量占总蛋白质含量的 39%。

As a industrial by-product from fermentation, protein of rice residue was hydrolyzed by papain. Premium working conditions for the enzymolysis were determined by means of orthogonal experiments. The enzymolysis liquid wasmade into a beverage of amino acid and protein, in which the protein concentration was 0.18% and the content of EAA in total protein 39%.
