Embodiment 1
[0028] This embodiment includes the following steps:
[0029] A. Selection: select nine-mature fresh mushroom bodies with complete bodies for selection and grading;
[0030] B. Sterilization: use ultraviolet light to irradiate the fresh mushroom body spread out in a single layer;
[0031] C. Packing: Lay a wood pulp paper layer on the inner wall of the turnover box, stack the sterilized fresh mushroom bodies into the turnover box, and place wooden pulp paper on the fresh mushroom bodies at intervals of 7-10cm in thickness. Pulp paper layer, a wood pulp paper layer is laid on the top of the fresh mushroom body to close the turnover box;
[0032] D. Modified atmosphere preservation: Put the full turnover box into the modified atmosphere packaging bag, vacuumize the packaging bag, and then inject the prepared fresh-keeping gas into the bag;
[0033] E. Storage: Store the modified atmosphere packaging bag under refrigerated conditions.
[0034] Through manual sorting, take out ...
Embodiment 2
[0044] In this example, the tea tree mushroom that has been packaged is placed under the condition of 2~4°C, and the tea tree mushroom can be placed for 30 days. On the 30th day, the weight loss rate of the tea tree mushroom is 6.3%, and the decay rate is 3.8%. A good tea tree mushroom can be placed under the condition of 4~10°C for 20 days. On the 20th day, the weight loss rate of tea tree mushroom is 6.7%, and the rot rate is 3.5%. Put the packaged tea tree mushroom in 11 Under the condition of ~15℃, tea tree mushroom can be placed for 15 days. On the 15th day, the weight loss rate of tea tree mushroom is 7.5%, and the rot rate is 3.0%. At the same time, the tea tree mushroom can be placed for 10 days. On the 10th day, the weight loss rate of the tea tree is 7.2%, and the rot rate is 2.5%. It can be concluded that under the storage condition of storage temperature 2~20℃, the lower the temperature, the smaller the loss of tea tree mushroom, and the better the effect of inhibi...
Embodiment 3
[0046] In this embodiment, on the basis of Example 1, for tea tree mushrooms with less storage capacity, the mushroom body can be placed in the modified atmosphere packaging bag. Similarly, the mushroom body is layered by two layers of wood pulp paper , then vacuumize and inject fresh air, and finally put the modified atmosphere packaging bag in the environment of 2~4℃ for low-temperature storage, and in this low-temperature environment, the tea tree mushroom can be stored for 30 days, and on the 30th day, the tea tree mushroom The weight loss rate reaches 6.3%, and the rot rate is 3.8%, which ensures the good quality of tea tree mushroom, and can meet the long-distance transportation of tea tree mushroom from the production base to the low-production area of tea tree mushroom, and achieve the purpose of extending the shelf life of tea tree mushroom.
