Embodiment 1

[0009] The fresh-keeping method of Agaricus bisporus with high oxygen adjustment, specifically implement the following steps: (1) Pre-cooling of Agaricus bisporus: pre-cool the Agaricus bisporus after harvesting in a cold storage at 2°C for 10 h; (2) Put the Agaricus bisporus in a closed box In the body, a partition is arranged near the bottom of the box to place Agaricus bisporus, and the bottom is equipped with 0.03% ethanol solution. (3) Treat Agaricus bisporus by fumigation with ethanol for 3 hours at 20°C. (4) Take Agaricus bisporus out of the airtight box, place it in the air for 20 minutes, pack it in plastic bags, and store it at 2±1°C and 90% relative humidity. Under these storage conditions, the storage period of Agaricus bisporus can be extended for more than 7 days, and there is no quality deterioration such as browning, umbrella opening, and rot, and still maintains good product quality and marketability.

Embodiment 2

[0011] The fresh-keeping method of Agaricus bisporus with high oxygen adjustment, specifically implement the following steps: (1) Pre-cooling of Agaricus bisporus: pre-cool the Agaricus bisporus after harvesting in a cold storage at 2°C for 12 hours; (2) Put the Agaricus bisporus in a closed box In the body, a partition is arranged near the bottom of the box to place Agaricus bisporus, and the bottom is equipped with 0.06% ethanol solution. (3) Treat Agaricus bisporus by fumigation with ethanol for 3 hours at 20°C. (4) Take Agaricus bisporus out of the airtight box, place it in the air for 30 minutes, pack it in plastic bags, and store it at 2±1°C and 95% relative humidity.

[0012] Under this storage condition, the storage period of Agaricus bisporus can be extended for more than 10 days, and there is no quality deterioration such as browning, umbrella opening, and rot, and still maintains good product quality and marketability.

Abstract

The invention relates to an ethanol fumigation treatment freshness retaining method for preventing agaricus bisporus from browning. The ethanol fumigation treatment freshness retaining method comprises the following steps of: precooling the agaricus bisporus in a refrigerator at 2 DEG C for 10-12 hours; then, performing ethanol fumigation on the agaricus bisporus at 20 DEG C in a closed box body for 3 hours, wherein a partition plate is close to the bottom in the box body, so that the agaricus bisporus can be placed conveniently, and an ethanol solution with the concentration of 0.03-0.06 percent is arranged at the bottom of the box body; and after the treatment, placing the agaricus bisporus, which is taken out of the closed box body, in air for 20-30 minutes, subpackaging the agaricus bisporus by plastic bags, and storing the agaricus bisporus in the plastic bags at 2+ / -1 DEG C and under relative humidity of 90-95 percent. By the freshness retaining method, the problems that the agaricus bisporus is very easy to brown and short in storage period are mainly solved, and the storage period of the agaricus bisporus can be prolonged by 7-10 days at room temperature.

Description

technical field [0001] The invention provides an ethanol fumigation treatment preservation method for preventing browning of Agaricus bisporus, and belongs to the technical field of preservation of edible fungi. Background technique [0002] Agaricus bisporus has high water content, delicate tissue, and no obvious protective structure on the surface of the cap. After harvesting at room temperature for 1 to 2 days, a large amount of water in the mushroom body evaporates and loses, and browning of Agaricus bisporus will occur, which will lead to its quality and product quality. A drop in value or even a complete loss. Therefore, postharvest browning control technology of Agaricus bisporus has become the key to solving the problem of storage, transportation and preservation of Agaricus bisporus. [0003] As a secondary metabolite naturally produced by plants, ethanol has a strong bactericidal effect. The use of appropriate exogenous ethanol can inhibit the post-ripening of fr...
