Embodiment 1

[0043] 1. Prepare fresh frozen liquid

[0044] The used composition of preparation fresh frozen liquid is: by weight 0.3% water-soluble chitosan, by weight 2% trehalose, by weight 5% glycerin, by weight 0.5% calcium chloride, balance for water. First, the water-soluble chitosan is fully stirred and dissolved in water, then trehalose, glycerin and calcium chloride are added, stirred and dissolved to obtain fresh frozen liquid. The freezing point of the fresh frozen liquid was determined to be -1.3°C. Place the fresh frozen solution in a -1°C refrigerator overnight, and the fresh frozen solution will be in a liquid state after overnight.

[0045] 2. Fresh Cordyceps treatment

[0046]Take 70 pieces of fresh Cordyceps sinensis stored in the refrigerator (-2°C), slowly thaw them at room temperature, and soak them in the fresh frozen liquid in the refrigerator (-1°C). Sterilized glass tubes were sealed with silicone stoppers.

[0053] 1. Prepare fresh frozen liquid

[0054] The used composition of preparation fresh frozen liquid is: by weight 1.2% water-soluble chitosan, by weight 5% trehalose, by weight 15% glycerin, by weight 2% calcium chloride, balance for water. First, the water-soluble chitosan is fully stirred and dissolved in water, then trehalose, glycerin and calcium chloride are added, stirred and dissolved to obtain fresh frozen liquid. The freezing point of the fresh frozen liquid was determined to be -6.5°C. Place the fresh frozen solution in a -6°C refrigerator overnight, and the fresh frozen solution will be in a liquid state after overnight.

[0055] 2. Fresh Cordyceps treatment

Abstract

The invention relates to the field of fresh-keeping of Chinese medicinal materials, and discloses a fresh frozen liquid, a fresh-keeping method thereof and an application thereof. The fresh frozen liquid comprises water-soluble chitosan, glycerin, trehalose and calcium chloride; the fresh-keeping method comprises the following steps: (1) pre-cooling the fresh frozen liquid under the condition of -1 DEG C to -7 DEG C; (2) placing fresh Cordyceps sinensis in the pre-cooled fresh frozen liquid in step (1) for 5 to 30 minutes; and (3) placing the fresh Cordyceps sinensis after the immersion treatment in step (2) at -1 DEG C to -7 DEG C under refrigeration. The fresh Cordyceps sinensis is treated with the fresh frozen liquid is fresher than that of a direct refrigerator frozen-storage method, and the preservation time is extended by at least 14 days.

Description

technical field [0001] The invention relates to the field of fresh-keeping of traditional Chinese medicinal materials, in particular to a fresh-keeping solution of fresh Cordyceps sinensis and a fresh-keeping method for fresh Cordyceps sinensis using the fresh-keeping solution.
