A biomass water-retaining agent suitable for mushroom sticks and its preparation method and application

Abstract

The invention belongs to the technical field of agricultural materials, relates to the field of edible fungus cultivation supplies, and particularly relates to a biomass water-retaining agent suitable for mushroom fungus sticks and a preparation method and application. The biomass water-retaining agent is prepared by use of green safe polymer polyvinyl alcohol as a base film forming agent and adding of the appropriate amount of carrageenan, glycerin and sodium tripolyphosphate, by dip-coating of the mushroom fungus sticks with the prepared biomass water-retaining agent, a layer of translucent protective film is formed on the surface of the mushroom fungus sticks, the protective film is a water-retaining film, and can replace a plastic film, when in fruiting time, manual cutting is not needed, mushroom buds in the mushroom fungus sticks can burst by themselves the water-retaining film without affecting the use of other regional water-retaining film, the fruiting body deformity can be effectively avoided, the flower mushroom quality can be improved, labor input and environmental pollution governance can be reduced, and the food safety problem during mushroom growth can be avoided.

Description

technical field [0001] The invention belongs to the field of agricultural materials, and in particular relates to a biomass water-retaining agent suitable for mushroom sticks, a preparation method and an application. Background technique [0002] Shiitake mushrooms are the second largest edible mushroom product in the world, and China is the largest producer and exporter of shiitake mushrooms in the world. Among them, the "flower mushroom" in shiitake mushrooms is recognized as the top grade among shiitake mushrooms. It is characterized by large flowers, thick mushrooms, low water content, Long shelf life and well-known at home and abroad. The cultivation of traditional shiitake mushrooms uses natural materials, no pests, no pesticide pollution, and maintains natural and pure characteristics. Therefore, it is well-known in the mushroom world for its pure taste, aroma, quality, and clean skin. Jane. At present, flower mushroom cultivation has opened up a new industrial road...

AI Technical Summary

Problems solved by technology

[0003] The production of shiitake mushrooms is a labor-intensive industry, especially in the cultivation of flower mushrooms. Heat preservation and moisture retention are important conditions for cultivating flower mushrooms. Therefore, it is particularly important to maintain the necessary moisture and temperature in the mushroom sticks during the production process. The plastic film is artificially cut (artificially cut the plastic film corresponding to the outer layer of the mushroom stick and each mushroom of the mushroom stick, so as to facilitate the traditional hand-cut bag (cut film) that the mushroom buds drill out from the bottom ) method), this method is labor-intensive and time-consuming, and the discarded plastic film after mushrooming is easy to produce white pollution

[0004] In order to save labor and reduce deformed mushrooms, in recent years there have been planting with cut-free bags, or removing plastic films and applying paraffin, inorganic water-retaining agents, etc. Although some labor can be saved to a certain extent, during the growth and picking of shiitake mushrooms, there will be Residues of cut-free bags, paraffin or water-retaining agent components cause food safety problems of shiitake mushrooms
