Lepista sordida mycelium rich in anthocyanidin and culture method for lepista sordida mycelium and application of lepista sordida mycelium

Abstract

The invention discloses a lepista sordida mycelium rich in anthocyanidin and a culture method for the lepista sordida. mycelium and application of the lepista sordida mycelium. The culture method comprises the following steps: aerated fermentation cultivation is performed on a lepista sordida strain for 4-6 days; a solid culture medium to which additives are added is used during culture, and the additives include yeast copper, tea polyphenol, vitamin C, yeast zinc, ferrous glycinate, riboflavin and L-phenylalanine; and in addition, magnetic field treatment starts to be used in the second day after culture. According to the scheme of the invention, a certain culture method is employed on the lepista sordida mycelium at the later stage of culture to make the mycelium rich in anthocyanidin, and thus, the industrial utilization of the mycelium is facilitated, and the blank of research and utilization of the anthocyanidin in edible fungi at present is remedied; a new way is opened to development and utilization of the anthocyanidin of the edible fungi; and the mycelium has considerable economic benefits and far-reaching social benefits.

Description

technical field [0001] The invention relates to the technical field of edible fungi, in particular to an anthocyanin-rich mycelium of the pleurotus chinensis and a cultivation method and application thereof. Background technique [0002] With the improvement of people's understanding of chemically synthesized pigments and the quality of life requirements, the application and development of natural pigments have attracted more and more attention and attention. Natural pigments mainly come from animals, plants and microorganisms. Most of the natural pigments are non-toxic to the human body, and some natural pigments also have health care effects, such as carotene, lycopene, and chlorophyll. At present, among the many pigments on the market, red, yellow, green, orange and blue are the mainstream of the natural pigment market, mainly due to the wide range of sources of these pigments and the relatively mature extraction process. In contrast, the market share of purple pigments ...

AI Technical Summary

Problems solved by technology

The mycelium of the pleurotus chinensis is gray-white and fluffy in the early stage, grows vigorously and thickly, and turns purple in the later stage of cultivation. After research, the mycelium of the pleurotus chinensis contains a very small amount of anthocyanins. Because the anthocyanin content is too low, the existing technology In China, the development of Pleurotus chinensis mainly focuses on its antibacterial and antioxidant activities, but there are few studies on the pigments contained in it.
