Abstract

The invention discloses a method for improving the VD in the fruiting bodies of edible and medicinal fungi. 2 The method for content comprises the following steps: (1) making the fruit body of edible and medicinal fungus into a suspension; (2) controlling the irradiation temperature at 30°C-60°C, and ultraviolet rays at different single wavelengths, combined wavelengths or stepwise combined wavelengths Under light irradiation, stir the suspension for 0.5h-4h. The benefit of the present invention is that it significantly improves the VD in the fruiting bodies of edible and medicinal fungi 2 content, thereby improving the nutritional value and functional edible quality of edible and medicinal fungi, how to stabilize and improve the VD in edible and medicinal fungi 2 The scientific problem of content provides green, economical, convenient, and easy-to-promote theoretical support and solutions, and opens up new ideas for the accumulation and strengthening of functional nutrients in edible and medicinal fungi.

Description

technical field [0001] The invention relates to a method for improving VD 2 The method for content, specifically relates to a kind of method for improving the VD in the fruit body of edible and medicinal fungus 2 The content method belongs to the technical field of food nutrition. Background technique [0002] Vitamin D 2 (VD 2 ) is an important member of the vitamin D family, which can regulate the metabolism of calcium and phosphorus and promote bone health. It is clinically used for the prevention and treatment of rickets, osteomalacia and hypoparathyroidism and other diseases. VD 2 The human body cannot synthesize it by itself, and it is transformed from ergosterol on the fungal cell membrane through a photoreaction of ultraviolet radiation. [0003] Edible mushrooms are rich in VD 2 Proto-ergosterol, which can be converted into VD under the irradiation of ultraviolet light 2 , however different transformation conditions affect VD 2 There is a significant differe...
