Abstract

The invention provides a method for processing nut meat rich in antioxidant peptide. The method is carried out according to the following steps: (1) the nut meat (containing groundnut kernels, macadamia nut kernels, walnut kernels, hazelnut kernels, cashew kernels, pistachio kernels and the like) is cut into small blocks of 5-10 mm; (2) the nut meat in the step (1) is put into ultrasonic equipment, and the nut meat is treated for 20-30 min at the power of 500-1000 w; (3) nut meat powder obtained in the step (2) is put into a reaction tank, the material-water ratio is (1:3) to (1:5), neutral proteinase of 1.2-2.0 g / kg is added, and hydrolysis is conducted for 20-30 min; (4) papain of 1.0-1.5 g / kg is added after reaction in the step (3), and hydrolysis is conducted for 20-30 min; (5) after reaction in the step (4), a seasoner is added, and after negative-pressure soaking for flavoring is conducted for 10-20 min, the nut meat is taken out to be drained for 1 h; and (6) the nut meat is subjected to tunnel-type microwave drying, the conveying speed is 5-10 m / min, and after being dried, the nut meat is subpackaged to obtain a product. The nut meat produced through the process contains the antioxidant peptides, an antioxidant cannot be added, nutrition is rich, safety is achieved, and the shelf life can be prolonged by 1-2 months.

Description

technical field [0001] The invention relates to a method for processing nut kernels rich in antioxidant peptides, belonging to the field of agricultural product processing. . Background technique [0002] Nuts are rich in nutrients, especially high in fatty acid content, so the oxidative deterioration of nuts is a major problem in the industry. At present, most of the antioxidants commonly used in the food industry are chemically synthesized, such as BHA (tert-butylhydroxyanisole), BHT (2,6-di-tert-butyl-4-p-cresol), BHQ (tert-butyl-p-phenyl diphenol), which itself has toxic side effects. The invention combines biological enzymatic hydrolysis technology to partially hydrolyze nut protein to release antioxidant peptides, which not only increases nutrition, but also delays nut oxidation and prolongs shelf life. Contents of the invention [0003] The object of the present invention is a method for processing nut kernels rich in antioxidant peptides. The technical solution ...
