Problems solved by technology

[0003] According to reports, the fruiting bodies of mushrooms naturally form a certain amount of formaldehyde under the action of mushroom enzymes during the growth and development process. The formaldehyde content is stable during the growth process, but the formaldehyde content increases by 3-4 times during the drying process after harvesting. Its value is obviously higher than that of other edible fungi; the existence of formaldehyde in shiitake mushrooms seriously endangers the health of consumers, and also restricts the export of edible fungi

Abstract

The invention belongs to the technical field of edible fungus storage, and particularly relates to a method of drying picked shiitake mushrooms. The method of drying picked shiitake mushrooms comprises the steps that Sl, apple polyphenol treatment is conducted, specifically, the shiitake mushrooms are fumigated with an apple polyphenol solution containing salt at a temperature of 40 to 50 DEG C; S2, adhesive coating is conducted, specifically, the surface is coated with 8 to 10 [mu]m lignin adhesive; S3, primary drying is conducted, treatment is conducted with a temperature of 80 to 90 DEG C;S4, amino acid treatment is conducted, specifically, an amino acid solution is used for fumigation at the temperature of 80 to 90 DEG C; S5, secondary drying is conducted, drying treatment is conducted in an oven at 90 to 100 DEG C; and S6, film forming treatment is conducted, specifically, the shiitake mushrooms are put in a gel solution, treated under ultrasonic conditions, removed, placed in anoven at 70 to 80 DEG C for drying treatment. According to the method of drying the picked shiitake mushrooms, a polyphenol layer, a bonidng layer, an amino acid layer, and a gel protective layer aresequentially formed on the surface of the shiitake mushrooms, respiration intensity of picked shiitake mushrooms is significantly inhibited, increasing of formaldehyde content is delayed, and commerciality of the shiitake mushrooms is improved.

Description

technical field [0001] The invention belongs to the technical field of edible fungus storage, in particular to a method for drying mushrooms after harvesting. Background technique [0002] Lentinus edodes, also known as mushrooms and black mushrooms, is known as "the king of mushrooms", "the food of God", and "the meat of vegetarians". Its meat is crisp and tender, delicious, unique in aroma, rich in sugar, protein, Vitamins and minerals, etc., have various functional activities such as preventing bone and cardiovascular diseases, anti-tumor, anti-oxidation, and anti-aging. Contains more than 200mg of vitamin C. [0003] According to reports, the fruiting bodies of mushrooms naturally form a certain amount of formaldehyde under the action of mushroom enzymes during the growth and development process. The formaldehyde content is stable during the growth process, but the formaldehyde content increases by 3-4 times during the drying process after harvesting. Its value is obvi...
