Abstract

The invention relates to a preparation method of a controllable edible fungus stick water-retaining agent material, which belongs to the technical field of edible fungi. The technical solution of the present invention uses bentonite to compound acrylic acid and acrylamide substances, and the two are combined together through polymerization to cause physical crosslinking. The product has good water absorption, water retention and salt resistance. Filled with protease material, in the initial stage of water-retaining agent use, a large amount of silk fibroin inside the water-retaining agent is decomposed and the macromolecular chain is enzymatically hydrolyzed into a small molecule polypeptide structure, which effectively reduces the compactness of the material structure, greatly reduces the water retention performance, and accelerates water loss. In the late stage of enzymatic hydrolysis, the small molecule peptides in the water-retaining agent material are absorbed by the fungus sticks. After being used as nutrients, the water-retaining performance is greatly reduced, and the water retention is low, preventing excessive water in the later use of the fungus sticks, and effectively controlling the water in the growth process of edible fungi. Slowly decrease, thus effectively improving the water retention and controllable performance of the water retaining agent material.

Description

technical field [0001] The invention relates to a preparation method of a controllable edible fungus stick water-retaining agent material, which belongs to the technical field of edible fungi. Background technique [0002] Since 1980, the cultivation of edible fungi in my country has created a history of artificial mass cultivation of "mushroom sticks". Pressed into a rod shape with a diameter of 10 cm and a length of about 40 cm, put it into a specific plastic bag, and then undergo cooking, heating, cooling and aging, inoculation and other processes. Generally, the average temperature is below 25°C (usually from November to the next year) May) mushrooms can be grown in stages. But its core problem is the water retention performance of the fungus stick after removing the plastic cover and entering the cultivation period. The surface of the fungus stick is very rough, the surface area is large, and it is easy to evaporate water, but mushroom cultivation needs water. In this r...
