Embodiment 1

[0019] Example 1: A method for pretreatment of rice straw suitable for industrialized cultivation of Stropharia stropharii and its preparation method

[0020] A method for pretreatment of rice straw suitable for industrial cultivation of Stropharia stropharii, comprising the following steps:

[0021] (1) Put bundled and packaged degreening fresh rice straws in a pool or water tank for 2-3 minutes and soak them out for 2-3 minutes, or spray them with water to complete the preliminary pre-wetting process. Spraying through with water means that the water content of the rice straw bale is 20-40%. In this embodiment, after measurement, the water content of the rice straw bales is 25%.

[0022] (2) subpackage the pre-wetted rice stalks in a suitable container and put them in an autoclaved container;

[0023] (3) At the beginning of the steam treatment process, firstly, the cold air in the sterilizer needs to be exhausted by raising the temperature, and then continue to pass steam ...

Embodiment 2

[0027] Example 2: A method for pretreatment of rice straw suitable for industrialized cultivation of Stropharia stropharii and its preparation method

[0028] (1) Put the bundled fresh rice straw in a pool or water tank to soak for 2.5 minutes, pick it up, and pack it into plastic bags that can be sterilized by high temperature and high pressure.

[0029] (2) After putting the soaked rice straw into the sterilization bag, use a punching device to punch holes on the left and right sides of the sterilization bag. There are 6 holes on each side, and 3 holes are evenly distributed in a row, a total of 12 holes of 0.5 cm size holes.

[0030] (3) Put the above-mentioned sterilizing bag containing rice straw in the sterilizer, and start the steaming process. First, it is necessary to raise the temperature to exhaust the cold air in the sterilizer, and then continue to pass steam into the sterilizer, and wait for When the over-sterilizing temperature rises to 110°C, close the intake ...

Embodiment 3

[0034] Example 3: A method for pretreatment of rice straw suitable for industrialized cultivation of Stropharia stropharii and its preparation method

[0035] A method for pretreatment of rice stalks suitable for industrial cultivation of Stropharia stropharia. The specific steps are as follows: put bundled and packaged degreened fresh rice stalks in a container and soak them for 2-3 minutes to remove them, or spray them with water, Complete the preliminary pre-wetting process; pack the pre-wetted rice straw into a suitable container and place it in a high-pressure sterilization container; start the steam treatment process, firstly need to heat up to exhaust the cold air in the sterilizer, and then continue to sterilize Pass steam through the sterilizer to keep the temperature of the sterilizer at 100-115°C for 20-30 minutes, and take it out after cooling to 70°C; the rice straw after steam treatment is sprayed with clean tap water for 1-2 minutes, and the water content That c...

Abstract

The invention discloses a pretreatment method and a preparation method of rice straws applicable to industrial cultivation of stropharia rugoso-annulata. The preparation method includes the steps: firstly, bundling fresh water-removing rice straws to obtain rice straw bales; and pre-wetting the rice straw bales; secondly, placing the pre-wetted rice straw bales into a high-pressure sterilization container; thirdly, heating the container to discharge cold air in the high-pressure sterilization container, leading steam into the high-pressure sterilization container, maintaining the temperature in the sterilization container to reach 100-115 DEG C, stopping lead-in of the steam after 20-30 minutes, and taking out the rice straws after the temperature in the high-pressure sterilization container is reduced to 65-75 DEG C to obtain the rice straws treated by the steam; fourthly, spraying the rice straws treated by the steam by clean tap water to obtain the rice straws with the water contentof 70%. According to the method, wax layers on the surfaces of the rice straws are removed by steam, so that the follow-up pre-wetting effect of the rice straws is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and relates to a method for pretreatment of rice straw suitable for industrialized cultivation of Stropharia stropharii. Background technique [0002] Stropharia rugosoannulata, also known as stropharia rugosoannulata, belongs to Basidiomycota, Agaricomycetes, Agaricales, Strophariaceae , Stropharia. In 1980, the Institute of Edible Fungi of the Shanghai Academy of Agricultural Sciences successfully cultivated it for the first time in China after being introduced from Poland. In 1992, Yan Shuwan, a researcher at Fujian Sanming Institute of Fungi, used rice straw as the main raw material to cultivate and achieved good results. However, the pre-wet treatment of rice straw has always been a difficult point in the pre-treatment of Stropharia stropharia raw materials, because the waxy layer on the surface of rice straw hinders the entry of water, making it difficult for pre-wet to ...
