Problems solved by technology

At present, the research on this aspect has been reported, such as Chinese patents 97242596.9, 02145222.9, etc., but they are all similar to the water retention technology of the double-bag mushroom planting, and have a common disadvantage that the mechanical properties of the inner film are low, and it is easy to scratch and produce cracks. , so the water retention capacity of the film is greatly reduced, and the fungus sticks are susceptible to mold, which in turn affects the normal yield of shiitake mushrooms
The most important thing is that the inner plastic film is difficult to degrade completely, which seriously pollutes the environment with rice; another report uses paraffin-soaked fungus stick water retention technology to grow shiitake mushrooms, but paraffin wax is easy to remain on shiitake mushrooms, which poses food safety hazards and serious Harm the physical and mental health of consumers

Embodiment 1

[0013] The mushroom stick coating liquid contains the following components: 10% of polyvinyl alcohol, 8% of starch, 2% of stearic acid, 3% of water-retaining agent sodium tripolyphosphate, and 77% of distilled water.

[0014] Install an electric stirrer, an electric heating mantle and a thermometer on a 1000mL three-necked flask, add 462g of distilled water into the three-necked flask, heat to 70°C, add 60g of polyvinyl alcohol, and stir for 30min. Then the solution was cooled to below 45°C, 48g of starch was added, the water bath was kept warm and stirring was continued for 30min. Finally, 12g of stearic acid and 18g of water-retaining agent sodium tripolyphosphate were added to the above-mentioned solution of polyvinyl alcohol and starch reaction, and a shear emulsifying mixer was used to stir at a high speed for 10 minutes, so that the mixed solution was emulsified under the action of shear force. A uniform, stable and viscous liquid coating solution was obtained, with a so...

Abstract

The invention discloses a biodegradable lentinus edodes strain stick coating liquid and preparation method thereof, which relates to a culture technique of lentinus edodes and comprises the following components, by mass percent, 10-12% of polyvinyl alcohol, 8-10% of starch, 2-4% of stearic acid, 3-5% of water retention agent, and the balance distilled water. When the product is used for culturing the lentinus edodes, the coating liquid is coated on the strain stick removing a plastic bag, so as to form a uniform and stable water retaining film with appropriate thickness. The film is flexible, moist and ventilative, and can prevent the loss of nutrient substances effectively; and the lentinus edodes bud can burst the water retaining film itself, without artificial incision. The fruiting body deformation can be avoided, thereby reducing the workload of bud sparseness and artificial incision. The popularization and application of the product can improve the quality and yield of lentinus edodes on the one hand, and on the other hand can save resource and labor force, decrease white pollution, develop recycling economy, thereby having good application prospect.

Description

technical field [0001] The invention relates to a mushroom stick coating liquid and a preparation method thereof, in particular to a mushroom stick coating liquid developed from biodegradable biomass materials and a preparation method thereof, belonging to the technical field of fine chemistry. Background technique [0002] At present, the cultivation method of shiitake mushrooms usually adopts the method of bag material cultivation. The basic production process of shiitake mushroom bag material cultivation is shown in the attached figure. In the production process, in order to maintain the necessary moisture in the mushroom sticks to ensure the normal growth of shiitake mushrooms, manual cutting is now generally used Fruiting, but manual cutting is difficult to solve the actual contradiction in the production of shiitake mushrooms, which is easy to cause a large amount of water evaporation in the mushroom stick due to sufficient cutting, and the caps of young mushrooms with ...
