Abstract

The invention discloses edible mushroom protein powder with high organic selenium content and a preparation method and application thereof. The pulse voltage is utilized to assist the alkaline solution to extract the effective components of the edible mushrooms, extraction is efficient, and damage of strong base to the effective components is avoided. Chitosan is utilized to enrich protein, polysaccharide and selenium in an extracting solution under alkaline and acidic conditions respectively, then isoelectric precipitation and alcohol precipitation are performed to collect the protein and the polysaccharide, effective components are collected as sufficiently as possible, and especially the selenium content is increased. The chitosan is further modified, and the organic modifier is degraded and grafted, so that a good adsorption and precipitation effect is kept while the absorption rate of the product is improved. The obtained edible mushroom protein powder with high organic selenium content is high in yield, high in selenium content, good in absorptivity and strong in health-care function, and can be applied to preparation of selenium-enriched food.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to an edible fungus protein powder with high organic selenium content, a preparation method and an application. Background technique [0002] Edible fungi refer to a class of large fungi that can form large fleshy (or gelatinous) fruiting bodies or sclerotia-like tissues, and can be used for human consumption or medicine. Its protein content is higher than that of ordinary fruits and vegetables, which is rich in essential amino acids for the human body, and has a complete variety, and has excellent health care effects. Organic selenium refers to the organic compound of selenium. The selenoprotein in animals and plants is a kind of natural organic selenium, which is the main form of selenium to function in the body. It has high biological activity and has the functions of relieving fatigue and enhancing immunity. [0003] The content of selenoprotein in natural ...
