Problems solved by technology

[0004] It can be seen that in the prior art, there are many defects in the fresh-keeping technology of Camellia oleifera, which leads to unsatisfactory fresh-keeping treatment of Camellia oleifera fresh-keeping. Mushrooms need to be controlled at a processing time of 0.5 minutes, which makes the processing conditions particularly harsh and difficult to keep fresh; moreover, after 1-2 minutes of processing time, the fresh-keeping effect will not be ideal.

Embodiment 1

[0022] The fresh-keeping method of Camellia oleifera Ozone nitrogen combined treatment comprises the following steps:

[0023] (1) Select nine mature mushrooms with complete body for sorting and grading;

[0024] (2) Lay a wood pulp paper layer on the inner wall of the turnover box, and stack the fresh camellia oleifera mushrooms into the turnover box. The thickness of each layer is 8-9cm, and the layers are separated by wood pulp paper layers. The top layer is closed with a wood pulp paper layer; achieves water retention and moisturizing effect.

[0025] (3) Put the turnover box full of fresh mushrooms of camellia oleifera into a modified atmosphere packaging bag, vacuumize the packaging bag, and fill it with ozone-nitrogen mixed gas with a mixing volume ratio of 1:0.3 until the packaging bag is full, and process After 0.3 min, the mixed gas was pumped out to make the inside of the packaging bag a vacuum, and it was stored under refrigeration at a temperature of 2°C.

Embodiment 2

[0027] The fresh-keeping method of Camellia oleifera Ozone nitrogen combined treatment comprises the following steps:

[0028] (1) Select nine mature mushrooms with complete body for sorting and grading;

[0029] (2) Lay a wood pulp paper layer on the inner wall of the turnover box, and stack the fresh camellia oleifera mushrooms into the turnover box. The thickness of each layer is 8-9cm, and the layers are separated by wood pulp paper layers. The top layer is closed with a wood pulp paper layer; achieves water retention and moisturizing effect.

[0030] (3) Put the turnover box filled with fresh mushrooms of camellia oleifera into a modified atmosphere packaging bag, vacuumize the packaging bag, and fill it with ozone-nitrogen mixed gas with a mixing volume ratio of 1:1.5 until the packaging bag is full. After 2 minutes, the mixed gas was pumped out to make the inside of the packaging bag a vacuum, and it was stored under refrigeration at a temperature of 4°C.

Embodiment 3

[0032] The fresh-keeping method of Camellia oleifera Ozone nitrogen combined treatment comprises the following steps:

[0033] (1) Select nine mature mushrooms with complete body for sorting and grading;

[0034] (2) Lay a wood pulp paper layer on the inner wall of the turnover box, and stack the fresh camellia oleifera mushrooms into the turnover box. The thickness of each layer is 8-9cm, and the layers are separated by wood pulp paper layers. The top layer is closed with a wood pulp paper layer; achieves water retention and moisturizing effect.

[0035] (3) Put the turnover box filled with fresh mushrooms of camellia oleifera into a modified atmosphere packaging bag, vacuumize the packaging bag, and fill it with ozone-nitrogen mixed gas with a mixing volume ratio of 1:1 until the packaging bag is full. After 1 minute, the mixed gas was pumped out to make the inside of the packaging bag a vacuum, and it was placed in a refrigerated condition at a temperature of 3°C for stora...

Abstract

The invention relates to the technical field of oil-tea mushroom preservation, in particular to a preservation method for oil-tea mushrooms through ozone-nitrogen combined treatment. The ozone-nitrogen mixed gas is adopted for treating in a vacuum packaging bag for 0.3 to 2min, so that the surfaces of the oil-tea mushroom bodies are subjected to sterilization and disinfection treatment, the time control on ozone treatment is reduced, the damage of the ozone on the surfaces of the oil-tea mushroom bodies is improved under the mixed action of the nitrogen, the preservation on the oil-tea mushroom bodies cannot be influenced within a longer time (around 1 to 2min), the preservation period of the oil-tea mushrooms is prolonged, and the weight loss ratio and the rotting rate are reduced throughcombining the treatment under the vacuum refrigeration condition.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping technology of camellia oleifera mushroom, in particular to a fresh-keeping method of camellia oleifera mushroom through combined treatment with ozone and nitrogen. Background technique [0002] Camellia oleifera is a kind of tea tree mushroom. It is delicious, crisp and delicious, and rich in nutrition. It is an edible fungus that people like to eat. Camellia oleifera is difficult to store and transport under normal conditions. 2-3 days after fresh mushrooms are harvested, there will be a large amount of water loss and shrinkage. A large number of fresh mushrooms are concentrated and sold in nearby markets, resulting in a market situation where the supply of mushrooms exceeds demand, causing the price of Camellia oleifera to drop sharply, seriously damaging the interests of mushroom farmers, and restricting the development of the Camellia oleifera industry. In the area of ​​the base, the ma...
