Embodiment 1

[0012] A method for preparing an edible fungus fresh-keeping agent, comprising the following steps: 1) sequentially adding 5 parts by weight of chitosan, 5 parts by weight of vitamin C, 1 part by weight of potassium sorbate and 5 parts by weight of pullulan 100 parts by weight of sterile water, stirred evenly to make a mixed solution; 2) ultrasonically disperse the mixed solution obtained in step 1) on an ultrasonic disperser for 30 minutes to make a dispersion solution; 3) process the dispersed solution obtained in step 2) Subpackage, sterilize and seal to obtain the preservative.

Embodiment 2

[0014] A method for preparing an edible fungus fresh-keeping agent, comprising the following steps: 1) Adding 7 parts by weight of chitosan, 8 parts by weight of vitamin C, 3 parts by weight of potassium sorbate and 7 parts by weight of pullulan 110 parts by weight of sterile water, stirred evenly to make a mixed solution; 2) ultrasonically disperse the mixed solution obtained in step 1) on an ultrasonic disperser for 50 minutes to make a dispersion solution; 3) process the dispersed solution obtained in step 2) Subpackage, sterilize and seal to obtain the preservative.

Embodiment 3

[0016] A method for preparing an edible fungus fresh-keeping agent, comprising the following steps: 1) sequentially adding 10 parts by weight of chitosan, 10 parts by weight of vitamin C, 5 parts by weight of potassium sorbate and 10 parts by weight of pullulan 120 parts by weight of sterile water, stirred evenly to make a mixed solution; 2) ultrasonically disperse the mixed solution obtained in step 1) on an ultrasonic disperser for 60 minutes to make a dispersion solution; 3) process the dispersed solution obtained in step 2) Subpackage, sterilize and seal to obtain the preservative.

Abstract

The present invention discloses an edible fungus preservative and a preparation method thereof and belongs to the technical field of fruit and vegetable preservation. The edible preservative comprises the following raw materials in parts by weight: 5-10 parts of chitosan, 5-10 parts of vitamin C, 1-5 parts of potassium sorbate, 5-10 parts of pullulan and 100-120 parts of sterile water. The present invention also provides the edible fungus preservative preparation method and the edible fungus preservative is prepared by mixed, ultrasonic dispersion, packing together. The preservative is diluted and the diluted preservative is directly sprayed onto the surface of the collected edible fungus. The edible fungus preservative can be used for the preservation of small-bagged edible fungi and also be used for the preservation of the edible fungi stored in large quantities. The edible fungus preservative is low in cost and long in preservation time, can extend the preservation and storage period to 30 days, is good in quality control, fully guarantees the freshness and nutrients of the edible fungi, is free of any toxic or side effects to human body and safe and environmentally friendly, and meets the various needs of people for the edible fungi.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, in particular to an edible fungus fresh-keeping agent and a preparation method thereof. Background technique [0002] As an important part of residents' diet, edible mushroom food provides human beings with rich protein, dietary fiber, vitamins, trace elements and other nutrients; however, due to its own physiological characteristics and the limitations of traditional fresh-keeping methods, its fresh-keeping time Difficult to get maximum extension. [0003] At present, the existing edible fungi are generally dried to prolong their storage period, or are kept fresh by methods such as quick-freezing, refrigeration, chemistry, air conditioning, microwave freeze-drying, etc., to prolong the shelf life and storage period of fresh edible fungi. This method of quick-freezing, refrigeration and freeze-drying has played a role and achieved certain effects on the preservatio...
