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.

Embodiment 1

[0028] Embodiment 1 of the present invention is: a kind of method for cultivating the mycelia of the mushroom rich in anthocyanins, comprising the following steps:

[0029] The fungus strains were taken for aeration and fermentation at 25°C. The formula of the medium used in the cultivation process was: solid medium and additives. The additives included yeast copper, tea polyphenols, vitamin C, yeast zinc, iron glycinate, Riboflavin and L-phenylalanine; additives added in an amount of 8mg / g. The mass ratio of yeast copper, tea polyphenols, vitamin C, yeast zinc, iron glycinate, riboflavin and L-phenylalanine is 5:3:2:3:2:2:1:3. The solid medium is prepared from the following raw materials in parts by weight: 200 parts of potatoes, 20 parts of agar, 2 parts of glucose, 3 parts of sucrose, 2 parts of maltose, 0.5 parts of peptone, 8 parts of soybean powder, 1 part of magnesium sulfate heptahydrate and water 1000 copies. The culture time is 4 days; the ventilation volume in the...

Embodiment 2

[0030] Embodiment 2 of the present invention is: a kind of cultivation method of the mycelium of the pleurotus chinensis rich in anthocyanins, comprises the following steps:

[0031] The fungus strains were taken to carry out aerated fermentation culture at 20°C for 5 days; the aeration volume in the fermentation culture was 1.2dm 3 / min. The formula of the medium used in the cultivation process is: solid medium and additives, the additives include yeast copper, tea polyphenols, vitamin C, yeast zinc, iron glycinate, riboflavin and L-phenylalanine; the amount of additives added is 10mg / g. The mass ratio of yeast copper, tea polyphenols, vitamin C, yeast zinc, iron glycinate, riboflavin and L-phenylalanine is 3:3:4:3:3:1:1:1. The solid medium is prepared from the following raw materials in parts by weight: 200 parts of potatoes, 20 parts of agar, 2 parts of glucose, 2 parts of sucrose, 2 parts of maltose, 0.5 parts of peptone, 6 parts of soybean powder, 1.0 parts of magnesium...

Embodiment 3

[0032] The third embodiment of the present invention is: a method for cultivating the mycelia of the anthocyanin-rich mushroom, comprising the following steps:

[0033] Fermentation and cultivation at 25°C were carried out on the strains of Cedaria edodes. The cultivation time was 6 days; the ventilation volume in the fermentation cultivation was 1.1dm 3 / min. The formula of the medium used in the cultivation process is: solid medium and additives, the additives include yeast copper, tea polyphenols, vitamin C, yeast zinc, iron glycinate, riboflavin and L-phenylalanine; the amount of additives added is 5mg / g. The mass ratio of yeast copper, tea polyphenols, vitamin C, yeast zinc, iron glycinate, riboflavin and L-phenylalanine is 2:3:3:2:2:1:3:3. The solid medium is prepared from the following raw materials in parts by weight: 200 parts of potatoes, 20 parts of agar, 1.5 parts of glucose, 2.5 parts of sucrose, 1.5 parts of maltose, 0.4 parts of peptone, 8 parts of soybean po...

Abstract

The invention discloses an anthocyanin-rich mycelium of the variegated mushroom and its cultivation method and application, comprising the following steps: taking the variegated variegated strain for aerated fermentation culture, and the culturing time is 4 to 6 days; the culturing process solid medium with supplements including yeast copper, tea polyphenols, vitamin C, yeast zinc, iron glycinate, riboflavin, and L‑phenylalanine were used in deal with. The scheme of the present invention utilizes the mycelium of A. variegata in the later stage of cultivation to adopt a certain cultivation method to make it rich in anthocyanins, which is conducive to its industrial utilization, and to make up for the gap in the current research and utilization of anthocyanins in edible fungi. The development and utilization of anthocyanins provides a new way, which 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 ...
