Embodiment 1

[0015] A method for preserving bamboo fungus, comprising the following steps:

[0016] Step (1): After harvesting the Dictyophora, place the Dictyophora in a cold storage at 0°C for 1 hour;

[0017] Step (2): Wrap the Dictyophora frozen in step (1) with plastic wrap;

[0018] Step (3): Put the Dictyophora treated in step (2) into a packaging bag filled with nitrogen, keep the positive pressure inside the packaging bag, and seal it.

[0019] After the packaging bag is sealed in step (3), there is room for the activities of the bamboo fungus in the packaging bag.

Embodiment 2

[0021] A method for preserving bamboo fungus, comprising the following steps:

[0022] Step (1): After harvesting the Dictyophora, put the Dictyophora in a cold storage at 3°C ​​for 3 hours;

[0023] Step (2): Wrap the Dictyophora frozen in step (1) with plastic wrap;

[0024] Step (3): Put the Dictyophora treated in step (2) into a packaging bag filled with nitrogen, keep the positive pressure inside the packaging bag, and seal it.

[0025] After the packaging bag is sealed in step (3), there is room for the activities of the bamboo fungus in the packaging bag.

Embodiment 3

[0027] A method for preserving bamboo fungus, comprising the following steps:

[0028] Step (1): After harvesting the Dictyophora, put the Dictyophora in a cold storage at 2°C for 2 hours;

[0029] Step (2): Wrap the Dictyophora frozen in step (1) with plastic wrap;

[0030] Step (3): Put the Dictyophora treated in Step (2) into a packaging bag filled with nitrogen, keep the positive pressure inside the packaging bag, and seal it.

[0031] After the packaging bag is sealed in step (3), there is room for the activities of the bamboo fungus in the packaging bag.

Abstract

The invention discloses a preservation method of bamboo fungi. The preservation method includes the following steps that (1) after harvesting of the bamboo fungi, the bamboo fungi are placed in a refrigeration house at 0-3 DEG C for 1-3 hours; (2) the bamboo fungi refrigerated in step (1) are wrapped in preservative film; (3) the bamboo fungi treated in step (2) are loaded into packaging bags filled with nitrogen, the positive pressure of the interiors of the packaging bags is maintained, and the packaging bags are sealed. By means of the preservation method of the bamboo fungi, the bamboo fungi can be preserved for a longer time.

Description

technical field [0001] The invention relates to the technical field of Dictyophora preservation, in particular to a method for preserving Dictyophora. Background technique [0002] After harvesting, bamboo fungus is easy to brown and rot when placed in the air when the temperature is high. At room temperature, it will brown and rot within 3-5 days and lose its commodity value. Therefore, bamboo fungus is a highly perishable product that is traded and circulated in the market. Only dry goods, no fresh products. These characteristics of bamboo fungus restrict the long-term storage and transportation of fresh products, making it difficult to sell fresh products, and the maximization of commodity value is restricted. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a method for preserving Dictyophora, which can store Dictyophora for a longer period of time. [0004] To achieve the above objec...
