Embodiment 1

[0016] A fresh-keeping method of white boletus, comprising the following steps:

[0017] 1) Pre-cooling treatment of white boletus: Select 10 kg of fruiting bodies of white boletus that are free from insects and mechanical damage, lay them flat in a plastic frame, and pre-cool at a constant temperature of 6°C for 2 hours.

[0018] 2) Disinfection treatment: After the pre-cooling step, before putting into the modified atmosphere fresh box step, first fumigate with 1-methylcyclopropene 6°C with a concentration of 0.6 μl / L for 12 hours, and then put the white boletus seeds The entity is placed in the modified atmosphere fresh-keeping box, placed in a cold storage at 6°C for 0.5 hour pre-cooling, and at the same time sterilized with ultraviolet rays 3 times, each time for 15 minutes, with an interval of 30 minutes.

[0019] 3) Vacuumizing and aeration treatment: after the pre-cooling step and disinfection step, the air in the controlled atmosphere box is evacuated to vacuum, and f...

Embodiment 2

[0022] A fresh-keeping method of white boletus, comprising the following steps:

[0023] 1) Pre-cooling treatment of white boletus: Select 10 kg of fruiting bodies of white boletus that are free from insects and mechanical damage, spread them flat in a plastic frame, and pre-cool at a constant temperature for 3 hours at 4°C.

[0024] 2) Disinfection treatment: After the pre-cooling step and before the step of putting into the modified atmosphere fresh box, fumigate with 1-methylcyclopropene 6°C with a concentration of 0.3 μl / L for 12 hours, and then put the white boletus seeds The entity is placed in the modified atmosphere fresh-keeping box, placed in a cold storage at 4°C for 1 hour, and sterilized twice with ultraviolet rays, each time for 20 minutes, with an interval of 40 minutes.

[0025] 3) Vacuumizing and aeration treatment: After the pre-cooling and disinfection steps, the air in the controlled atmosphere box is evacuated to vacuum, and filled with 88% nitrogen, 4% ox...

Embodiment 3

[0028] A fresh-keeping method of white boletus, comprising the following steps:

[0029] 1) Pre-cooling treatment of white boletus: Select 10 kg of fruiting bodies of white boletus without moths and mechanical damage, spread them flat in a plastic frame, and pre-cool at a constant temperature for 2 hours at 8°C.

[0030] 2) Disinfection treatment: After the pre-cooling step, before putting into the modified atmosphere fresh box step, first fumigate with 1-methylcyclopropene at a concentration of 1 μl / L at 5°C for 10 hours, and then put the fruiting body of Boletus albicans Place it in the modified atmosphere fresh-keeping box, place it in a refrigerator for pre-cooling at 5°C for 0.6 hours, and simultaneously sterilize it with ultraviolet rays 4 times, each time for 18 minutes, with an interval of 30 minutes.

[0031] 3) Vacuumizing and aeration treatment: after the pre-cooling and disinfection steps, the air in the controlled atmosphere box is evacuated to a vacuum, and fille...

Abstract

The invention discloses a preservation method of boletus bainiugan dentinger. The preservation method comprises the following steps: firstly precooling the boletus bainiugan dentinger in a refrigeration house at 2-6 DEG C, sealing after being placed in a gas-adjusted fresh-preserved storehouse, and then cold-storing in the refrigeration house at 2-6 DEG C, wherein the concentration of nitrogen in the gas-adjusted fresh-preserved storehouse is 80-96%, the oxygen concentration is 2-10% and the carbon dioxide concentration is 2-10%. The storage period of the boletus bainiugan dentinger treated by using the method disclosed by the invention is prolonged by 6-9 days in comparison with the boletus bainiugan dentinger which is stored at 2-4 DEG C without the preservation treatment, and is prolonged by 10-15 days in comparison with the boletus bainiugan dentinger which is stored at 10-16 DEG C without the preservation treatment; and meanwhile, the conditions such as worm damage, rotting and lesion of the boletus bainiugan dentinger treated through the method disclosed by the invention can be obviously improved in the storage period, and the sensory quality such as the appearance, the flavor and the like can be well maintained.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping edible fungi, and in particular relates to a method for fresh-keeping of white boletus by controlled atmosphere. Background technique [0002] White boletus ( Boletus bainiugan Dentinger), the genus Hymenomycetes, Agaricales, Boletineae, Boletus Boletus , is a world-renowned wild edible fungus. According to the measurement, every 100g of dry product contains 20.0g of protein, 4.0g of fat, and contains all 20 kinds of amino acids, various trace elements and vitamins. Oxygen capacity, lowering blood fat; also has the effect of anti-cancer and anti-influenza virus. In the circulation of the existing white boletus industry chain, low-temperature refrigeration is mostly used for storage, that is, it can be stored for 0.5-1 day at a low temperature of 2-4° C. and a relative humidity of 90-95%. [0003] At present, in the research on the modified atmosphere preservation of white boletus, there...
