Embodiment 1

[0033] Embodiment 1: (Agaricus bisporus storage and preservation method 1)

[0034] Proceed as follows:

[0035] (1) raw material preparation: select the fresh Agaricus bisporus without mechanical damage and no damage by diseases and insect pests as raw material, set aside;

[0036] (2) Vacuum precooling: the step (1) Agaricus bisporus raw material is put into a vacuum precooling chamber by 5kg / basket; the moisture of 3% of the mushroom raw material weight is sprayed on the surface of Agaricus bisporus with a watering can, After placing the temperature probe in the middle of the basket, close the chamber door, and rapidly pre-cool the Agaricus bisporus temperature to 4°C within 15 minutes under a vacuum of 300Pa;

[0037] (3) Decompression storage: Place the Agaricus bisporus after vacuum precooling in step (2) at 3°C, 30KPa, store in a decompression freezer with a relative humidity of 95%; when the CO in the decompression freezer 2 When the concentration reaches 15%, start ...

Embodiment 2

[0038] Embodiment 2: (the preservation method 2 of Agaricus bisporus)

[0039] Proceed as follows:

[0040] (1) raw material preparation: with embodiment 1;

[0041] (2) Vacuum pre-cooling: the step (1) Agaricus bisporus raw material is put into a vacuum pre-cooling chamber by 8kg / basket; the moisture of 5% of the raw material weight of the mushroom is sprayed on the surface of Agaricus bisporus with a watering can, After placing the temperature probe in the middle of the basket, close the chamber door, and rapidly pre-cool the Agaricus bisporus temperature to 6°C in 23 minutes under a vacuum of 450Pa;

[0042] (3) Decompression storage: Place the Agaricus bisporus after vacuum precooling in step (2) at 4°C, 40KPa, store in a decompression freezer with a relative humidity of 90%; when the CO in the decompression freezer 2 When the concentration reaches 15%, start to exchange air with the outside of the warehouse, and adjust the CO in the warehouse 2 The concentration was ke...

Embodiment 3

[0043] Embodiment 3: (the preservation method 3 of Agaricus bisporus)

[0044] Proceed as follows:

[0045] (1) raw material preparation: with embodiment 1;

[0046] (2) Vacuum precooling: the step (1) Agaricus bisporus raw material is put into a vacuum precooling chamber by 10kg / basket; the moisture of 6% of the mushroom raw material weight is sprayed on the surface of Agaricus bisporus with a watering can, After placing the temperature probe in the middle of the basket, close the chamber door, and quickly pre-cool the Agaricus bisporus temperature to 8°C in 30 minutes under a vacuum of 600Pa;

[0047] (3) Decompression storage: Place the Agaricus bisporus after vacuum precooling in step (2) at 5°C, 50KPa, and store in a decompression freezer with a relative humidity of 85%; when CO in the decompression freezer 2 When the concentration reaches 15%, start to exchange air with the outside of the warehouse, and adjust the CO in the warehouse 2 The concentration was kept below 1...

Abstract

The invention discloses a storage and fresh keeping method for white mushroom, which belongs to the technical field of storage and fresh keeping of agricultural products. The method comprises the following steps of: (1) raw material preparation, (2) vacuum pre-cooling, and (3) reduced pressure storage and the like. The method quickly and effectively reduces the breathing intensity of the white mushroom, and delays the decomposition of nutrient components so that the primary white mushroom easy to produce brown stain, deterioration and cap opening is inhibited, the storage period of the white mushroom is prolonged to 12 to 15 days from the conventional 2 to 3 days, the shelf life is remarkably prolonged, and the method is simple, feasible and convenient for popularization. The method is suitable to be popularized and applied in major edible mushroom planters and sellers.

Description

technical field [0001] The invention relates to the technical field of storage and preservation of agricultural products, in particular to a storage and preservation method of Agaricus bisporus. Background technique [0002] Agaricus bisporus, also known as white mushroom, is the most widely cultivated, most productive and most widely consumed edible fungus in the world. Agaricus bisporus is not only a high-grade fungus vegetable, but also a nutritious food with good health effects. It is rich in protein and 8 kinds of essential amino acids, among which the content of lysine is more than 2 times higher than that of shiitake mushrooms. Agaricus bisporus is a high-protein, low-calorie, low-fat food. It is a green food especially suitable for the elderly and children. Arteriosclerosis has a certain therapeutic effect on patients with hyperlipidemia and diabetes. Agaricus bisporus has a high water content, soft tissue, and no protective structure on the surface, so its respir...
