Nontoxic cut-free flower mushroom stick composite water conservation film

Abstract

The invention provides a nontoxic incision-free mushroom stick water holding film, which is a film formed after congealing the following compounds: the weight percentage of food grade powdered glycerin monostearate is 60-90%, and the weight percentage of stearic acid is 10-40%. The water holding film not only can ensure the edible safety of produced mushroom but also has quick and even film production and moderate hardness, thereby having fine water holding capacity and moderate ventilation property; the production cost is 20-40% than olefin.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a water-retaining film for mushroom sticks. Background technique [0002] Flower mushrooms are the top grade of shiitake mushrooms. During the process of forcing flowers, the cultivation environment is required to be relatively dry, and the relative air humidity is required to be controlled at 50-68%. Technical problems in mushroom cultivation management. At present, two methods are generally adopted to retain water: one is to keep the mushroom sticks out of the bag to retain water. After the mushroom buds occur, use a blade to cut a hole on the surface of the plastic tube bag to expose the mushroom buds; the other is to apply a paraffin water-retaining film to retain water. After the color change of the flower mushroom sticks is completed and sporadic mushroom buds appear, the outer plastic tube bag of the flower mushroom sticks is removed, and a l...

AI Technical Summary

Problems solved by technology

Method 1 is labor-intensive and time-consuming, with low labor efficiency, and often causes small mushroom buds to dry up and die or mushroom caps to be deformed due to poor timing of cutting, which greatly reduces the commodity value of flower mushrooms; method 2 can avoid cutting, saving labor and labor. However, because industrial paraffin is a carcinogenic suspected poison, it will adhere to mushrooms, which has food quality and safety problems, and due to the sharp rise in oil prices, the cost of removing paraffin for each bag of mushroom sticks is too high, which has exceeded the affordability of mushroom farmers. s level
