Method for separating buckwheat anti-digestion endosperm cells and cotyledon nutrition powder in electric field

Abstract

The invention provides a method for separating buckwheat anti-digestion endosperm cells and cotyledon nutrition powder in an electric field, and relates to the technical field of grain deep processing. The method takes buckwheat as a raw material and comprises the following steps: mechanical shelling, crushing of shelled grains, dry grading, differential crushing, electrostatic field enrichment, superheated steam enzyme deactivation and separation to obtain resistant endosperm cells and cotyledon nutrition powder. The method separates the buckwheat structural layer by a physical method, the complete cell structure of buckwheat endosperm and the original characteristics of nutrient components in cotyledons can be reserved, meanwhile, the bitter taste in the cotyledon powder is reduced, andthe technological process is green, efficient and energy-saving.

Description

technical field [0001] The invention relates to the field of intensive processing of miscellaneous grains, in particular to a method for separating buckwheat anti-digestion endosperm cells and cotyledon nutrient powder by an electric field. Background technique: [0002] The grain of buckwheat consists of husk and buckwheat kernel. Buckwheat kernels are composed of three parts: endosperm, bran and cotyledon (germ). The endosperm is rich in starch, and the cotyledon and bran are rich in protein and dietary fiber respectively. Different from traditional grains, the unique cotyledon structure of buckwheat is located in the center of the endosperm, which needs to be equipped with a special milling process. Buckwheat is rich in flavonoids, and the flavonoid content in tartary buckwheat is as high as 2g / 100g, which is the highest among all grains; buckwheat is also rich in resistant starch, and its products have obvious anti-digestion and low GI properties. Therefore, buckwheat ...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned existing disclosed methods mainly adopt methods such as wet method, alkaline method and dry grinding to process buckwheat. Although buckwheat starch, protein and fiber with higher purity can be obtained, the tissue structure of buckwheat endosperm and cotyledon is destroyed, and the The digestion resistance of starch in buckwheat and the original function of cotyledon protein have a great impact; at the same time, the wet method will also increase the cost of sewage treatment, evaporation energy consumption, equipment, etc., which is difficult to apply to the existing grain processing industry
