Double-spore mushroom preserving agent

Abstract

The invention provides a preservative for Agaricus bisporus, which is characterized in that the preservative is composed of methyl cellulose 8-12g / L, calcium chloride 0.6-1.0g / L, ascorbic acid 0.3-0.5g / L, sorbic acid 0.4~0.6g / L, the rest is distilled water. After Agaricus bisporus is immersed in the antistaling agent, a layer of antistaling agent is coated on the surface of the mushroom. The antistaling agent interacts with different molecules during air-drying or natural drying to form a uniform and transparent semi-permeable film with a three-dimensional network structure. The semi-permeable membrane can close the pores on the surface of the mushroom to form a closed environment with tight permeability, which can effectively prevent O2 from entering the inside of the mushroom, slow down the outward diffusion of CO2 produced by the respiration of the mushroom, and form a gap between the semi-permeable membrane and the surface of the mushroom. A space with low O2 and high CO2. This space can effectively inhibit the physiological respiration of mushrooms, slow down the loss of nutrients, and can effectively reduce the infection of exogenous microorganisms, reduce the evaporation of water inside the mushrooms during storage, thereby maintaining the hardness and color of mushrooms, and the fresh-keeping period exceeds 10 sky.

Description

Technical field [0001] The invention provides a fresh-keeping agent for mushrooms bisporus, which belongs to the technical field of fresh-keeping edible fungi. Background technique [0002] Agaricus bisporus has high water content and very delicate tissue. There is no obvious protective structure on the surface of the cap. A large amount of water in the mushroom body will evaporate and lose, and the cap and gills will begin to break and open the umbrella after 1 to 2 days after harvesting at room temperature. , Atrophy, browning, or even decay, the stipe elongates, the value of the commodity decreases or even disappears. Moreover, bisporus mushrooms are mostly cultivated in remote mountainous areas and rural areas. The contradiction between production and sales is particularly prominent, which has brought huge losses to mushroom farmers. Therefore, solving the problem of keeping fresh mushrooms fresh after picking and extending their transportation and listing period is the only ...

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
