Abstract: The present invention relates to a method for precisely determining protein content in edible fungus, belonging to the technical field of food detection. The method is as follows: determining total nitrogen content in an edible fungus sample by using a Kjeldahl method; additionally taking an equal amount of sample, and washing same with acid and alkali solutions to obtain chitin residues; then determining nitrogen content in the chitin residues by using the Kjeldahl method; subtracting the nitrogen content in the chitin residues from the total nitrogen content in the sample, so as to eliminate the interference of the nitrogen content in chitin; and finally obtaining precise protein content by calculation based on a formula. The present invention provides a method for precisely determining protein content in edible fungus, and provides a method for the precise assessment of the nutrient composition and value of protein in the edible fungus.

Abstract: The present invention provides a method for promoting the growth and preservation quality of Agaricus bisporus, and belongs to the technical field of cultivation and preservation of edible fungi. In the present invention, the methyl jasmonate solution is sprayed onto the surface of Agaricus bisporus at a concentration of 10-200 ?mol/L when the Agaricus bisporus grows to the mushroom bud stage, which can accelerate the growth and development of the Agaricus bisporus, improve the post-harvest preservation quality of the Agaricus bisporus, and prolong the shelf life thereof, then improving the yield and commercial value of the Agaricus bisporus. The present invention provides a new method for increase in both production and income and post-harvest preservation of Agaricus bisporus, can be applied to large-scale industrial production of Agaricus bisporus, and has important economic benefits and application promotion value.
