Embodiment 1

[0026] Embodiment 1, a kind of method utilizing Schizophyllum mycelium to prepare degradable packaging material, comprises the following steps:

[0027] S101: Compost preparation: Mix 25 parts of corn stalks, 25 parts of wheat straw, 15 parts of apple sawdust, 10 parts of wheat husks, 10 parts of cottonseed hulls, 3 parts of lime, and 2 parts of gypsum; add the dry weight of materials to the compost 1.25-1.50 times of water, mix well, adjust the water content in the culture material to 55%-60%, then put it into a sterilization bag, and sterilize it on the high-pressure sterilization equipment for 2 hours.

[0028] S102: Pre-cultivation of strains: Inoculate the liquid strains of Schizophyllum into the fungus bag cooled to room temperature, cover the lid, and place it in a dark and constant temperature culture with a temperature of 20°C-25°C, a relative humidity of about 60%, and good ventilation. Cultivate in the box for 10-15 days until the material is covered with mycelium. ...

Embodiment 2

[0031] Embodiment 2, a kind of method utilizing Schizophyllum mycelium to prepare degradable packaging material, comprises the following steps:

[0032] S101: Preparation of compost: Mix 20 parts of corn stalks, 20 parts of wheat straw, 10 parts of apple sawdust, 5 parts of wheat husks, 5 parts of cottonseed husks, 1 part of lime, and 1 part of gypsum; add the dry weight of materials to the compost 1.25-1.50 times of water, mix well, adjust the water content in the culture material to 55%-60%, then put it into a sterilization bag, and sterilize it on the high-pressure sterilization equipment for 2 hours.

[0033] S102: Pre-cultivation of strains: Inoculate the liquid strains of Schizophyllum into the fungus bags cooled to room temperature, cover them, and place them in a well-ventilated dark constant temperature culture at a temperature of 20°C-25°C and an ambient relative humidity of about 60%. Cultivate in the box for 10-15 days until the material is covered with mycelium. ...

Embodiment 3

[0036] Embodiment 3, a kind of method that utilizes Schizophyllum mycelium to prepare degradable packaging material, comprises the following steps:

[0037] S101: Preparation of compost: Mix 22 parts of corn stalks, 22 parts of wheat straw, 12 parts of apple sawdust, 8 parts of wheat husks, 8 parts of cottonseed husks, 2 parts of lime, and 2 parts of gypsum; add the dry weight of materials to the compost 1.25-1.50 times of water, mix well, adjust the water content in the culture material to 55%-60%, then put it into a sterilization bag, and sterilize it on the high-pressure sterilization equipment for 2 hours.

[0038] S102: Pre-cultivation of strains: Inoculate the liquid strains of Schizophyllum into the fungus bags cooled to room temperature, cover them, and place them in a well-ventilated dark constant temperature culture at a temperature of 20°C-25°C and an ambient relative humidity of about 60%. Cultivate in the box for 10-15 days until the material is covered with mycel...

Abstract

The invention relates to a method for utilizing schizophyllum commune Fr. mycelia for preparing a degradable packaging material. The method comprises the steps of S101, preparation of a culture material, wherein corn straw, wheat straw, apple wood dust, wheat hulls, cottonseed hulls, lime and gypsum are uniformly mixed; water is added into the culture material for uniform mixing and sterilizing; S102, preliminary culturing of a culture, wherein a schizophyllum commune Fr. liquid culture is inoculated to a fungus bag which is cooled to the room temperature, and the fungus bag is covered with alid for culturing; S103, mold filling and culturing, wherein a disinfected packaging mold is filled with the material which is grown with the schizophyllum commune Fr. mycelia under aseptic conditions, and continuous culturing is conducted after compacting and sealing are conducted; S104, sample drying, wherein after the schizophyllum commune Fr. mycelia in the material of the mold are reunited, samples are taken out of the mold and dried to obtain the product. According to the method, the environment-friendly packaging material is prepared with the crop straw as main raw materials, the applewood dust and the wheat hulls as auxiliary raw materials and the schizophyllum commune Fr. mycelia as the binder, the problem that existing packages are non-degradable can be solved, and crop straw and fruit tree branches can also be better treated.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a method for preparing degradable packaging materials using schizophyllum mycelium. Background technique [0002] With the increasing white pollution and the increasing shortage of natural resources, degradable, green and environmentally friendly packaging materials are getting more and more attention from consumers. At present, the research on biomass fully degradable products has become a hot research topic at home and abroad. [0003] my country is a big agricultural country, and the actual corn output in 2016 was 224.63 million tons. According to the conversion relationship between corn output and straw amount: straw amount=1.2×corn output. In 2016, my country's straw was about 269.55 million tons. At present, the processing of corn stalks in my country is mainly to make biogas, make livestock food, make plant ash and return it to the field. Howeve...
