Abstract
The invention provides a zein bioactive peptide and a preparation technology thereof. The technology comprises the steps that: corn protein powder is crushed into fine powder of 80 to 100 meshes; water which is 8 to 15 times of the weight of corn protein powder is added so as to form slurry; autoclaving is carried out at the temperature of 121 DEG C for 10 to 20 min, the mixture is cooled down to 45 plus or minus 1 DEG C; neutral protease which is 0.1 to 0.5 time of the weight of the corn protein is added into the slurry, then zymohydrolysis is carried out at the temperature of 45 plus or minus 1 DEG C for 1.5 to 3.0 hours; the autoclaving is carried out at the temperature of 121 DEG C for 10 min, then the mixture is cooled down to 45 plus or minus 1 DEG C; an Aspergillus oryzae strain which is 10 percent of the total weight of the slurry is accessed aseptically at the temperature of 35 plus or minus 1 DEG C; and the mixture is put into a shaker for fermentation for 10 to 12 hours so as to obtain the zein bioactive peptide. The preparation technology of the invention has the advantages that: the reaction process is steady and easier to be controlled; the final product has low content of impurity and high content of amino acid, with good mouthfeel and no abnormal taste of bitter and harsh, etc., meanwhile, the production cost is relatively low.
