Problems solved by technology

[0006] Fresh Cordyceps sinensis is not easy to clean and store due to its high water content and more active ingredients
[0007] Many fresh Cordyceps sold in the market cannot be washed cleanly, and the surface contains sediment, parasite eggs, etc., which affects the food safety of fresh Cordyceps
In order to clean, the means used will more or less cause the loss of active ingredients
In addition, the general preservation method is not easy to preserve its moisture and active ingredients.

Embodiment 1

[0020] Example 1 Cleaning effect and SOD enzyme activity of fresh Cordyceps sinensis washed with low temperature water and fresh Cordyceps sinensis washed with normal temperature water

[0021] Take 150 newly excavated fresh Cordyceps sinensis, wash each 50 roots with 5°C water at 5°C ambient temperature, 10°C water at 10°C ambient temperature, and 25°C water at 25°C ambient temperature , count the time and qualified rate of the same grass brusher for brushing grass respectively, and detect the SOD enzyme activity of fresh Cordyceps sinensis after scrubbing.

[0022] The result is as follows:

[0023] Experimental treatment SOD enzyme activity (U / g) Elapsed time / min Pass rate / % 5 ℃ environment 5 ℃ water cleaning 11242.2 58 96％ 10°C environment 10°C water cleaning 11109.2 59 96％ 25 ℃ environment 25 ℃ water cleaning 9638.7 56 98％

[0024] Conclusion: As can be seen from the above table, there is little difference in the cleaning effect...

Embodiment 2

[0025] Example 2 Comparison of fresh-keeping effects of different grades of fresh Cordyceps sinensis at the same temperature and the same humidity

[0026] Wash the newly excavated fresh Cordyceps sinensis with 8°C water, and then divide them into three grades according to the weight less than 0.5g, 0.5-1.0g, and more than 1.0g under the environment of 8°C.

[0027] Prepare 60 fresh Cordyceps of each grade and store them in an environment with a temperature of -10°C and a humidity of 60%. Take out 10 fresh Cordyceps of each grade every half month to evaluate its color, hardness and moisture content.

[0028] The evaluation results are as follows:

[0029] Less than 0.5g experimental results

[0030] less than 0.5g day 0 day 15 day 30 Day 45 Day 60 Day 75 color golden golden yellow dark yellow black and yellow - hardness hard hard slightly soft softer very soft - moisture 75.50％ 73.21％ 71.40％ 70.33％ 68.71％ - ...

Embodiment 3

[0036] Example 3 Comparison of Fresh-keeping Effects of Fresh Cordyceps of the Same Grade at the Same Humidity and Different Temperatures

[0037] Take 240 fresh Cordyceps sinensis less than 0.5g, and store each 60 in the environment of -2°C, -3°C, -5°C, -7°C, and the humidity is 60%. Take out 10 to evaluate its color, hardness.

[0038] Take 240 pieces of fresh Cordyceps sinensis of 0.5~1.0g, and store each 60 pieces in the environment of -3°C, -5°C, -7°C, and -10°C respectively, and the humidity is 60%. Banyue took out 10 to evaluate its color and hardness.

[0039] Take 240 fresh Cordyceps larger than 1.0g, and store each 60 in the environment of -5°C, -7°C, -10°C, -12°C, and the humidity is 60%. Take out 10 to evaluate its color, hardness.

[0040] The experimental results are as follows:

[0041] Less than 0.5g experimental results

[0042]

[0043] 0.5~1.0g test results

Abstract

The invention relates to a method for preserving fresh cordyceps sinensis. The method disclosed by the invention comprises the following steps: performing low-temperature cleaning, low-temperature grading, graded storage and the like. The whole process is performed in a low-temperature environment, so that the preservation time of the fresh cordyceps sinensis is greatly prolonged, losses of active ingredients are reduced, and the preservation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping edible and medicinal fungi, in particular to a fresh-keeping method for fresh Cordyceps sinensis. [0002] technical background [0003] Cordyceps sinensis (Berk.) Sacc is a complex of larvae and larvae of the ergot fungus Cordyceps sinensis parasitizing on the larvae of the bat moth family insects. It is a traditional valuable nourishing medicinal fungus. [0004] Cordyceps sinensis grows on the Qinghai-Tibet Plateau at an altitude of more than 3,800 meters, and it is not easy to harvest. In order to prolong the storage time, most of the Cordyceps sinensis on the market is sold in the form of hay, but during the drying process, the loss of active ingredients will inevitably occur. At the same time, the common forms of consumption are mostly powdered and soup-based, which is troublesome. [0005] Fresh Cordyceps sinensis is welcomed by the market, the reason is firstly that there are more ac...
