Problems solved by technology

[0005] In order to solve the problems of quality loss, high cost, long thawing time and inconvenient storage in household refrigerators brought about by frozen storage of fresh Cordyceps sinensis, the inventors of the present invention have discovered a method for storage at temperatures above zero by using modified atmosphere packaging. It can solve the defects of various sub-zero storages of fresh Cordyceps sinensis

Embodiment 1

[0034] 200 pieces of fresh Cordyceps sinensis with soil were manually peeled off at 21°C, and the surface of the insects, especially the sediment, bacterial film, eggs, etc. in the folds, were washed with a soft toothbrush under running water at 18°C, and no foreign matter was visible to the naked eye. Observe carefully under a microscope at 10 times, if foreign matter is observed, return to running water and wash until no foreign matter is visible to the naked eye under the microscope; dry the surface moisture of the cleaned fresh Cordyceps sinensis on clean absorbent paper, and then grade according to Table 1.

[0075] Select B-grade products, and pack fresh Cordyceps sinensis with a volume of 272cm 3 KPET14 / PE50 modified atmosphere box, in the clean bench, according to the ratio of packaging volume (ml): fresh grass weight (g) = 40:1, packed into the air modified box, and then carried out modified atmosphere sealed packaging, in which the gas ratio is 20 vol% carbon dioxide, 70 vol% oxygen and 10 vol% nitroge...

Embodiment 3

[0081] 1,000 pieces of fresh Cordyceps sinensis with soil were manually peeled off at 5°C, and the surface of the insects, especially the sediment, bacterial film, eggs, etc. in the folds, were washed with a soft toothbrush under running water at 3°C, and no foreign matter was visible to the naked eye. Observe carefully under a microscope at 10 times, if foreign matter is observed, return to running water and wash until no foreign matter is visible to the naked eye under the microscope; dry the surface moisture of the cleaned fresh Cordyceps sinensis on clean absorbent paper, and grade according to Table 1.

[0082] Select C-grade products, put fresh Cordyceps sinensis in a KPET14 / PE50 modified atmosphere box with a packaging volume of 500ml, and put them in the air-conditioned box according to the ratio of packaging volume (ml): fresh grass weight (g) = 60:1 in a clean bench , followed by modified atmosphere sealed packaging, wherein the gas ratio is 10% by volume of carbon di...

Abstract

The invention relates to a preservation method for fresh cordyceps sinensis and a fresh cordyceps sinensis product. The preservation method provided by the invention comprises steps of sterilizing anair-conditioned packaging material to obtain the sterilized air-conditioned packaging material; hermetically packaging the clean fresh cordyceps sinensis with the sterilized air-conditioned packagingmaterial to obtain a packaged product, wherein the packaged product is filled with 50-100 vol% of oxygen, 0-40 vol% of carbon dioxide and 0-50 vol% of nitrogen. The packaged product is suitable for being preserved at 0-10 DEG C. The fresh cordyceps sinensis product provided by the invention is preserved through the preservation method for fresh cordyceps sinensis.

Description

technical field [0001] The invention relates to the field of processing fresh Chinese medicinal materials, in particular to a fresh-keeping method for fresh Cordyceps sinensis and fresh Cordyceps sinensis products. Background technique [0002] Fresh Cordyceps sinensis, because of the short storage period at temperatures above zero, is currently frozen and stored at sub-zero temperatures, but frozen storage costs too much for merchants to maintain low temperatures during transportation; Chinese patent CN201710006514.1 discloses a fresh Cordyceps sinensis The fresh-keeping method, which can reach the fresh-keeping period of 2 months when stored at 0~-10°C, so the frozen layer of the household refrigerator (-18°C) does not meet the fresh-keeping conditions of fresh Cordyceps sinensis, which brings inconvenience of low-temperature preservation; Chinese patent CN 201410019134.8 discloses a fresh-keeping method for fresh Cordyceps sinensis, which preserves the nutrients and activ...
