Abstract
The invention discloses a method for preparing pleurotus eryngii fungus sticks by fermenting chestnut peels. The method mainly utilizes the chestnut skin softening and fermenting technology and mainly comprises the following steps: the chestnut skin is firstly dried to remove partial water, then crushed into filamentous and flocculent fibers, then placed into a fermentation tank for fermentation, fished out after the fermentation is finished, and then mixed with other auxiliary materials for autoclaving. The chestnut skin used by the invention has the properties of sawdust, wood fiber and the like, contains carbohydrate and nutrient components such as sugar, iron and the like, replaces sawdust to prepare the pleurotus eryngii fungus sticks, can reduce the production cost, shorten the planting time, improve the nutrient conversion rate and cultivate high-quality and delicious pleurotus eryngii products.
Description
Technical Field
The invention belongs to the field of pleurotus eryngii planting, and particularly relates to a method for preparing pleurotus eryngii fungus sticks through fermentation of chestnut skins.
Background
The traditional raw materials for preparing the pleurotus eryngii mushroom sticks mainly comprise sawdust, the cost price per ton of the raw materials is on the trend of increasing year by year, and the market price of the pleurotus eryngii declines year by year, so that the profit margin for planting the pleurotus eryngii decreases year by year. In order to reduce the planting cost of pleurotus eryngii, the technical problem which is urgently needed to be solved is to find a substitute of sawdust for preparing the mushroom sticks.
According to Chinese medicine industry Journal of Pharm acids 201041 (2), 16 compounds are separated and identified from 95% ethanol extract of a receipt skin, and comprise various organic components which are suitable for being absorbed by human bodies, such as organic phenols, organic acids, polysaccharides, flavones and phytosterol. The isatis root bark is also a natural traditional Chinese medicine, is sweet and astringent in property, and has the effects of lowering adverse qi, stopping bleeding and the like. However, the preparation of mushroom sticks by replacing sawdust with chestnut peel has not been reported.
Disclosure of Invention
In order to solve the technical problems, the invention provides a method for preparing pleurotus eryngii fungus sticks by fermenting chestnut skins.
In order to achieve the purpose, the invention adopts the following technical scheme:
the method for preparing the pleurotus eryngii mushroom sticks by fermenting the chestnut peels comprises the following steps:
(1) Stacking the peeled Chinese chestnut peel in the open air, airing to eighty percent dry, and removing impurities;
(2) processing the dried chestnut peel into filiform and flocculent fibers by using a sawdust pulverizer;
(3) Stacking the processed chestnut skins in a fermentation tank, thoroughly spraying cold water, fermenting, and turning over every several hours;
(4) After the chestnut skin is fermented, the chestnut skin can be mixed with other auxiliary materials, added with water and stirred uniformly for more than 20 min;
(5) Detecting that the water content of the mixture is 63-70% and the pH value is 8.0-9.0, preparing a stick when the stick raw material is appropriate in elasticity and the fungus bag is not damaged and leaks air, and then placing the stick into a high-pressure fungus cabinet for sterilization;
(6) Sterilizing at 126 deg.C under 0.158KPa for 3.5 hr, taking out, cooling, and inoculating in an inoculating chamber when the temperature of the bacteria stick is below 26 deg.C.
further, the fermentation temperature in the step (3) is below 25 ℃.
Further, the fermentation time in the step (4) is not more than 24 hours, and the ingredients are required to be immediately mixed after the fermentation is finished.
Compared with the prior art, the method for preparing the pleurotus eryngii mushroom sticks by fermenting the chestnut skins has the following beneficial effects that:
(1) After the chestnut skin is used for making the stick, the pleurotus eryngii is planted, so that the hyphae of the pleurotus eryngii can grow faster, and the taste of the pleurotus eryngii product is better.
(2) the method for preparing the pleurotus eryngii fungus sticks by fermenting the chestnut peels can reduce the pleurotus eryngii planting cost and improve the yield value.
(3) the pleurotus eryngii mushroom sticks prepared by fermenting chestnut peels have higher nutrition conversion rate.

Detailed Description
Example 1
stacking the peeled Chinese chestnut peel in the open air, airing to eighty percent dry, and removing impurities; then processing the dried chestnut peel into filiform and flocculent fibers by using a sawdust pulverizer; stacking the processed chestnut skins in a fermentation tank, thoroughly spraying cold water, fermenting at the temperature below 25 ℃, and turning over once every several hours; soaking for 24 hr, softening chestnut skin, mixing with other adjuvants (such as corn cob and wheat bran), adding water, and stirring for more than 20 min; when the moisture content of the mixture is detected to be 63-70% and the pH value is 8.0-9.0, making a stick, wherein the stick raw material is required to be proper in tightness, and a fungus bag is not damaged and leaks air, and then pushing the stick into a high-pressure fungus cabinet for sterilization; sterilizing at 126 deg.C under 0.158KPa for 3.5 hr, taking out, placing in a cooling chamber, and inoculating in an inoculating chamber when the temperature of the bacteria stick is below 26 deg.C; inoculating in a hundred-grade clean room inoculation room, and then putting in a spawn running room to run spawn under the condition that the temperature is 23-25 ℃ and the air humidity is 70%; after the hyphae grow full, the temperature illumination and stimulation management are carried out, so that the hyphae are twisted into sporocarp, the air humidity is increased, and bud forcing and fruiting are promoted; when buds grow to 5-8 cm, selecting and reserving 2-3 roots for mushroom management, when the mushrooms grow to 14-20 cm, enabling the edges of pileus to be flat, and picking when the mushrooms are seven-eight mature when turning inwards.
Example 2
The mushroom sticks were prepared from sawdust and chestnut peel according to the ratios in tables 1 and 2, respectively.
TABLE 1 formulation one (sawdust bar) (0.6 kg/bar dry dose)
TABLE 2 formulation two (chestnut shell bar) (0.6 kg/bar based on dry dose)
As can be seen from the comparison of the table 1 and the table 2, the chestnut skin is saved by 0.09 yuan/stick compared with sawdust with different formulas and the same proportion.
Example 3
The sawdust stick and the chestnut peel stick prepared in example 2 were used for growing pleurotus eryngii, respectively, and the growth rate and the collection period of the mycelia were compared under the same management conditions.
TABLE 3 comparison of hypha growth rate and harvest cycle time under the same management conditions
As is clear from Table 3, the chestnut husk sticks were produced 7 days earlier than the sawdust sticks under the same management conditions.
Example 4
10 ten thousand fungus sticks are prepared according to the sawdust stick formula I shown in the table 1 of the example 2 and the chestnut skin stick formula II shown in the table 2 respectively, and the comparison tests of the cost, the total yield of the pleurotus eryngii, the yield of the single pleurotus eryngii and the like are carried out.
TABLE 4 bar stock cost conversion yield test results
As can be seen from Table 4, the total yield of the chestnut skin sticks is higher than that of the sawdust sticks in single stick, the nutrition conversion rate is 4%, the sales value is 0.15 yuan higher, and the raw material cost is 0.09 yuan lower, so that the yield value of the single stick is 0.24 yuan higher than that of the sawdust sticks, namely, the chestnut skin sticks are low in cost, hypha is produced quickly, the management period is short, the conversion rate is high, and the yield value is increased.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
