Description
Technical field
The invention belongs to field of packaging material more particularly to a kind of utilization Schizophyllum commune for Mycelium to prepare degradable package
The method of material.
Background technique
With white pollution increasingly aggravate and natural resources it is increasingly in short supply, degradable, green, environment-friendly package material is got over
To get over the attention by the majority of consumers.Currently, the correlative study of biomass full degradable product has become the heat studied both at home and abroad
Point.
China is large agricultural country, and corn actual production in 2016 is 2.2463 hundred million tons.It is changed according to corn yield and stalk amount
Calculation relationship: stalk amount=1.2 × corn yield.China's stalk in 2016 is about 2.6955 hundred million tons.China's corn stover is handled at present
Biogas is mainly made, domestic animal foodstuff, production plant ash returning to the field etc. are done.But it is incinerated using small scale and there are also a large amount of stalks,
Pollution is generated, the wasting of resources is also resulted in.The annual output of China's wheat stalk is about 1.8 hundred million tons or so, is gone out in some areas
The phenomenon that now huddling, disorderly abandon, or even burning, wheat stalk is treated as problem.In fact, wheat stalk is not waste,
But a kind of renewable resource of preciousness.
Apple is the big kind of yield first in all kinds of fruit in China, and China is maximum apple production state in the world.
In these years, China's apple production stablize increase, the whole city's cultivated area of the apple of Yantai in 2015 up to 2,720,000 mu, fruit-bearing forest branch
Pruning rate also year by year it is whole plus, discarded fruit-bearing forest branch should what course to follow become a Xiang Wenti.
There are many macro fungis in nature, using in extensive range.Many has been exploited for industrial fermentation and agriculture
Industry production.Schizophyllum commune (Schizophyllum commune Fr.) is a kind of edible medicinal macro fungi, is widely distributed in all over the world,
Food industry, medical and health, in terms of be widely used.Schizophyllum commune includes mycelium and fructification two parts group
At, fructification edible value is high, and matter is tender delicious, has special strong fragrance, and it is mild-natured, there is strengthening by means of tonics, sedation, be
High-grade edible and medical fungi.The bacterium mycelium contains more strongly active cellulase, and can generate malic acid, and when mycelia submerged fermentation can
Generate a large amount of organic acids, also can produce regulator heteroauxin, using its mycelium production packaging material there is not yet.
At present patent of invention (CN106633990A) using corn stover as the fungi based biomass packaging material of major ingredient and its
Preparation method, patent of invention (CN106633989A) are using bagasse as the fungi based biomass packaging material of major ingredient and its preparation side
Method, patent of invention (CN106633990A) are by fungi based biomass packaging material of major ingredient and preparation method thereof of corn stover
Column patent is all solely using a kind of material as major ingredient, and base-material requires relatively complicated, and not to be related to fire-resistance resistance to for only excellent mechanical property
It is aqueous；Patent of invention (CN104025909A) it is a kind of be inoculated with edible fungus species culture degradable package material method, have compared with
Good fire line, but without the advantage in weight.
Summary of the invention
Degradable package material is prepared using Schizophyllum commune for Mycelium in order to solve the above technical problem, the present invention provides a kind of
Method, the present invention is one kind based on agricultural crop straw, and apple sawdust, the Schizophyllum commune for Mycelium supplemented by wheat shell prepares packaging
The technology of material.
The present invention is achieved through the following technical solutions, and the present invention, which provides a kind of prepare using Schizophyllum commune for Mycelium, to drop
The method for solving packaging material, comprising the following steps:
S101: compost prepares: by corn stover, wheat stalk, apple sawdust, wheat shell, cotton seed hulls, lime, gypsum mixing
Uniformly；1.25 ~ 1.50 times of water of the dry weight that adds materials into compost mix, the water content in regulation culture raw material to 55%-
60%, it is then charged into sterilizing bag sterilizing；
S102: strain preculture: schizophyllum commune liquid spawn is inoculated in the bacterium bag being cooled to room temperature, and covers lid culture；
S103: mold filling culture: the spectacle case for aseptically having sterilized the material for covering with Schizophyllum commune for Mycelium filling is die-filling
In tool, continue to cultivate after being pressed and sealed；
S104: sample drying: after Schizophyllum commune for Mycelium is tied again in the material in mold, sample is taken out of mold
It is dried out to the water content of sample and is lower than 20%, degradable package material can be obtained.
The present invention, for primary raw material, is made with plant fiber (wheat shell, wheat stalk, corn stover etc.) and apple branch
It is standby a kind of novel based on the mycelial degradable package material of macro fungi；Raw material extensive, preparation process with raw material sources
Simply, low in cost, the advantages that Life cycle is pollution-free, belong to environmental type packaging material, and can make full use of
Agricultural straw resource has wide promotion prospect.
Schizophyllum commune is a kind of edible medicinal macro fungi, is widely distributed in all over the world, in food industry, medical and health, bioid
Learn etc. is widely used.Schizophyllum commune includes mycelium and fructification two parts composition, and fructification edible value is high, the tender taste of matter
Beauty has special strong fragrance, mild-natured, has strengthening by means of tonics, sedation, for high-grade edible and medical fungi.The bacterium mycelium contains
More strongly active cellulase, and can generate malic acid, when mycelia submerged fermentation, can produce a large amount of organic acids, also can produce growth-promoting
Plain heteroauxin, using its mycelium production packaging material there is not yet.
Preferably, material is added and is calculated by weight as: 20~25 parts of corn stovers, 20~25 portions of wheats in S101
