Problems solved by technology

[0003] In terms of post-harvest browning prevention technology of mushrooms, although there are some methods at present, they all have certain defects: for example, sulfites are used for color protection in domestic fresh sales and processing, but most importing countries do not allow mushrooms and their processed products to contain Sulfite residues prevent the processed mushrooms and processed products from being exported; the use of cobalt-60 radiation treatment or high-pressure treatment not only requires specific equipment and high cost, but also has hidden safety hazards in the use process, which is difficult to promote; Treatment methods such as controlled atmosphere and low-temperature refrigeration, the fresh-keeping period of the treated Agaricus bisporus is only 5-7 days, and it is difficult to meet the requirements of long-term storage and transportation

Embodiment 1

[0011] (1) Harvesting: Do not spray water one day before Agaricus bisporus is harvested. Harvest first or second tide mushrooms with a diameter of 30-40mm. During the harvesting process, you should handle them with care. Select mushrooms with complete body, white color, For Agaricus bisporus that has not been opened, and has no pests and mechanical damage, one layer of mushrooms and one layer of paper are placed in a cardboard box with uniform holes, so as to avoid mechanical damage to the surface of the mushroom body;

[0012] (2) Pre-cooling: the Agaricus bisporus placed in the carton after harvesting is quickly placed in a cold storage at 2°C and RH90% for 11 hours;

[0013] (3) Storage and preservation: place the pre-cooled Agaricus bisporus with the carton in a controlled atmosphere warehouse with a relative humidity of 95±2% and a temperature of 2.1-2.6°C. Leave a certain gap to prevent poor gas circulation during storage, causing the local gas concentration to fail to m...

Embodiment 2

[0016] (1) Harvesting: Do not spray water one day before Agaricus bisporus is harvested. Harvest first or second tide mushrooms with a diameter of 30-40mm. Handle gently during the harvesting process. Select mushrooms with complete body, white color, For Agaricus bisporus that has not been opened, and has no pests and mechanical damage, one layer of mushrooms and one layer of paper are placed in a cardboard box with uniform holes to avoid mechanical damage to the surface of the mushroom body;

[0017] (2) Pre-cooling: the Agaricus bisporus placed in the carton after harvesting is quickly placed in a cold storage at 2°C and RH90% for 13 hours;

[0018] (3) Storage and preservation: place the pre-cooled Agaricus bisporus with the carton in a controlled atmosphere warehouse with a relative humidity of 95±4% and a temperature of 1.1-1.8°C. The amount of mushrooms loaded is 65% of the warehouse volume. Leave a certain gap to prevent poor gas circulation during storage, causing the ...

Abstract

The invention relates to a method for keeping the dual-spore mushroom fresh, which comprises collecting and pre-cooling the dual-spore mushroom. The invention is characterized in that the pre-cooled dual-spore mushroom is arranged in the air adjusting room at 50-80% volume, while the humidity of room is 95+-4% and the temperature is 1-3Deg. C; the air adjusting room is fed the mixture of O2, CO2 and N2, to confirm the O2 density at 4.6-5.3% and the CO2 density at 15.0-17.05< and the volume ration between O2, CO2, and N2 at 3-6:15-20:74-82. Compared with present technique, the invention can store the dual-spore mushroom with air adjustment, to prolong the storage period to 15 days with simple process, low cost and non-chemical left.

Description

Technical field [0001] The invention belongs to the technical field of fresh-keeping edible fungi, and in particular relates to a modified-atmosphere fresh-keeping method for Agaricus bisporus. Background technique [0002] Agaricus bisporus is one of the important edible fungi cultivated worldwide, and its output accounts for about 70% of the total amount of edible fungi. It is delicious, has high nutritional value, is rich in protein (about 3.5% to 4.5% of fresh weight), and 8 kinds of amino acids necessary for human body. It is an ideal high-protein, low-fat, low-calorie health food for human beings. However, due to the high water content of Agaricus bisporus, 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. Umbrella opening, water loss, shrinkage, browni...
