Double-spore mushroom preserving agent

Abstract

The present invention provides a bi-spore mushroom preservative, which is characterized in that the preservative comprises the methyl cellulose 8 to 12 g / L, the calcium chloride 0.6 to 1.0 g / L, the ascorbic acid 0.3 to 0.5 g / L, the sorbic acid 0.4 to 0.6 g / L, and the rest of the distilled water. After the preservative is immersed into the bi-spore mushroom, a layer of preservative is coated on the surface of the mushroom; in the air drying or natural drying process, the different molecules of the preservative are interacting with each other to form a uniform and transparent tri-dimensional structural semipermeable membrane, which can close the air holes on the surface of the mushroom so as to form a closed environment having the strict permeation; which can effectively prevent the oxygen entering into the interior of the mushroom, slowing down the outward diffusion of the carbon dioxide caused by the respiration of the mushroom so as to form a space with less oxygen and more carbon dioxide between the semipermeable membrane and the surface of the mushroom. The space can effectively prevent the biological respiration of the mushroom, slow down the consumption of the nutrients, effectively reduce the infringe of the foreign microorganism and reduce the evaporation of the water inside the mushroom during the storage period, thereby maintaining the hardness and the color of the mushroom and enabling the preservation period of the mushroom to exceed ten days.

Description

Technical field [0001] The invention provides a bisporus fresh-keeping agent, which belongs to the technical field of edible fungus fresh-keeping. Background technique [0002] Agaricus bisporus has a high water content, the tissue is very delicate, and there is no obvious protective structure on the surface of the cap. After 1 to 2 days of harvesting at room temperature, a large amount of water in the mushroom body will evaporate and lose, and the cap and gills will begin to rupture and open the umbrella. , shrinking, browning, or even rot, the stipe is elongated, and the commodity value decreases or even disappears. Moreover, Agaricus bisporus is mostly cultivated in remote mountainous areas and rural areas, and the contradiction between production and sales is particularly prominent, which has brought huge losses to mushroom farmers. Therefore, to solve the problem of post-harvest preservation of fresh mushrooms and prolong their transportation and marketing period is th...

Problems solved by technology

In the above-mentioned invention, because chlorine dioxide is used as a color-protecting agent, chlorine dioxide is a strong oxidizing agent, and its liquid state is unstable, and it is easy to decompose and produce chlorine gas. Unexpected color protection effect

And chlorine dioxide is mainly used as a kind of disinfectant at present, and there are not many applications in food, and the scope is not wide, such as the chemical industry mandatory standard "food additive stable state dioxide Chlorine Solution Standards clearly stipulates that the food additive chlorine dioxide solution is only suitable for use as preservatives and food processing aids in food processing; my country's "Hygienic Standards for the Use of Food Additives" (GB2760-1996) also clearly stipulates that food additives Chlorine dioxide is only used for antisepsis and preservation of fruits and vegetables, and for disinfection and sterilization in the fish processing industry
