Problems solved by technology

[0003] The purpose of the present invention is to address the risk of pesticide residues, low biotransformation rate and serious waste of degradable resources caused by the direct use of the main culture material of artificially cultivated edible fungi without detoxification and degradation treatment before production. Innovating on problems, using bioengineering technology to bioenzymolyze and biodegrade pesticide residues of crop straws with high crude fiber and lignin content and by-products of agricultural product processing to produce safe and efficient edible fungus main culture materials

Embodiment

[0068] Embodiment: the cotton stalk harvested in Liangxinbao Town, Junshan District, Yueyang in 2008 and the rice straw from Sanfengsi Town, Huarong County were made into edible fungus main culture materials according to the production method of this invention respectively.

[0069] (1) Choose and prepare materials

[0070] Select clean and dry raw material cotton stalks and straws, crush the cotton stalks and straws to about 2cm (such as skins, shells, chips, leaves, etc., to 20 meshes), put the crushed raw materials into the fermentation device, and then add 50% tap water by weight of raw materials, and stir evenly.

[0071] (2) Biological enzymatic hydrolysis of polymer substances

[0072] Add the prepared compound crude enzyme liquid into the fermentation device equipped with raw material cotton stalks and rice straw according to the amount of 10% of the above raw material weight, and stir evenly, keep warm at 45°C for 10hrs, and detect the crude fiber and lignin content ...

Abstract

The invention relates to a master culture medium material of edible fungi by manual culture, in particular to a safe and high-efficiency preparation method of the master culture medium material of edible fungi. The preparation method comprises the following steps of: firstly, selecting prepared materials, then carrying out biological enzymolysis to polymeric substances and carrying out biodegradation to pesticide residue, finally drying and obtaining a finished product. The preparation method starts with safety and high efficiency of the culture medium material of the edible fungi, utilizes the bioengineering technology to carry out biological enzymolysis to crop straws with high content of crude fiber and lignin and processed products of agricultural and sideline products such as peels, hulls, scraps, leaves and the like so as to improve nutritional value thereof, and simultaneously carry out biodegradation of pesticide residue to crop straws with high content of crude fiber and lignin and processed products of agricultural and sideline products such as peels, hulls, scraps, leaves and the like so as to prepare the safe and high-efficiency master culture medium material of the edible fungi. The safe and high-efficiency preparation method not only reduces the production cost of the edible fungi, improves bioconversion ratio of the edible fungi, but also reduces pesticide residue in the culture medium of the edible fungi and improves the quality safety of the edible fungi product.

Description

technical field [0001] The invention relates to a main culture material for artificially cultivating edible fungi, in particular to a method for making a safe and efficient main culture material for edible fungi. Background technique [0002] At present, in the production of edible fungi, crop stalks and by-products of agricultural product processing are mainly used as main culture materials, but the vast majority of crop stalks and by-products of agricultural product processing such as cotton stalks, cottonseed husks, straw, corn stalks, etc. The high content of lignin and cellulose is difficult to be metabolized and utilized by edible fungi, resulting in low biotransformation rate and long production cycle; on the other hand, there are high pesticide residues in crop straws and by-products of agricultural product processing, which brings great harm to the production of edible fungi. A great product quality and safety risk has come. Contents of the invention [0003] The...
