Embodiment Construction

[0017] (1) Avoid spraying water 2-3 days before harvesting edible fungi, and spray a small amount of natural biological preservatives (chitosan, polylysine, kojic acid, cinnamon oil, clove oil, etc.) Harvest the surface of the mushroom body (fruiting body) carefully, put it in a foam box with a polyethylene plastic bag to avoid damage to the edible fungus, and put it in a cold storage for 12-24 hours.

[0018] (2) Weigh and pack 100-500g of pre-cooled edible fungus into a 20-50cm×30-50cm polyethylene vacuum packaging bag, and then put in 10-30g of food desiccant (silica gel, montmorillonite or bentonite) And 5-30g of activated carbon, and avoid direct contact between edible fungus and desiccant and activated carbon.

[0019] (3) The vacuum sealing machine first evacuates, then fills the mixed gas of oxygen and nitrogen (the partial pressure of the mixed gas is oxygen: nitrogen = 50-100: 50-0) to atmospheric pressure, seals, and packs.

[0020] (4) The boxed edible fungi are s...

Abstract

The invention relates to new technology and a new method suitable for the storage and fresh keeping of edible mushrooms, belongs to the technical fields of the storage and processing of agricultural products and agricultural horticulture in food science and engineering, and relates to comprehensive technology and a comprehensive method for high-oxygen atmosphere packaging of the edible mushrooms, which can be applied to the storage and fresh keeping of flammulina velutipes, button mushrooms, pleurotus ferulae, lentinus edodes and the like. The edible mushrooms are delicious in taste and rich in nutrients, and have the diet therapy and health care effects of reducing cholesterol, preventing hypertension, gastrointestinal ulcer, hepatopathy and hyperlipemia, resisting cancers, improving organism immunity and the like. The edible mushrooms such as flammulina velutipes, the button mushrooms and the like are fresh food predominantly, but fresh mushrooms are easy to generate brown stain, pileus stretching and decay after picking due to high moisture, and thus the fresh mushrooms are short in refreshing time. The invention adopts the comprehensive fresh-keeping technology and the comprehensive fresh-keeping method such as high-oxygen atmosphere packaging technology (HOAP), natural food preservatives, food absorbent and the like to achieve the aims of retaining the freshness of the edible mushrooms, restraining bacteria, avoiding moisture loss, preventing pileus from stretching and browning, preventing the edible mushrooms from generating peculiar smell and prolonging the storage refreshing time of the edible mushrooms.

Description

Technical field: [0001] The invention belongs to the technical fields of processing and storage of agricultural products in food science and engineering and agricultural horticulture, relates to a comprehensive technology and method for high-oxygen controlled storage and preservation of edible fungi, and is applied to the production of edible fungi such as Flammulina velutipes, Agaricus bisporus, Bailing mushrooms, shiitake mushrooms, and oyster mushrooms. Store and keep fresh to prolong its storage period. Background technique: [0002] The scientific name of Flammulina velutiper (Flammulina velutiper (Fr.) Sing), also known as winter mushroom, golden mushroom, simple mushroom, common mushroom, structure bacteria, frozen bacteria, intelligence mushroom, etc., English is: "eniki mushroom". Because of its slender stipe, like day lilies, so it is called Flammulina velutipes, Flammulina velutipes belongs to the fungus door Basidiomycetes Agaricaceae Agaricaceae, and money fungu...
