Embodiment 1

[0027] A composite preservation method for flat mushrooms, comprising the following steps:

[0028] 1) Pre-harvest treatment: During the period from fruiting to harvesting of Pleurotus ostreatus, the compound liquid is sprayed twice on the mushroom body, and the last spraying time is three days before harvesting. The specific composition of the compound liquid is as follows: calcium gluconate quality Fraction is 3%, antioxidants are ascorbic acid 0.6mmol / L, glutathione 0.7mmol / L;

[0029] 2) Post-harvest treatment: remove the stalks of the harvested oyster mushrooms, and heal them in a ventilated environment at 13°C for 3 hours, so that the surface of the bacteria can dissipate the field heat and keep them dry;

[0030] 3) Immediately put the oyster mushrooms in the fresh-keeping film after the wound treatment, without tying the bag, put them in the basket, and then send them to the fresh-keeping store for pre-cooling to 5°C;

[0031] 4) Stop refrigeration, put the 95% ethano...

Embodiment 2

[0044] A compound fresh-keeping method for shiitake mushrooms, comprising the following steps:

[0045] 1) Pre-harvest treatment: During the period from fruiting to harvesting of shiitake mushrooms, the compound liquid is sprayed twice on the mushroom body, and the last spraying time is three days before harvesting. The specific composition of the compound liquid is as follows: the mass fraction of calcium gluconate 1.2%, calcium lactate mass fraction 0.3%, calcium chloride 0.9mmol / L, antioxidant, glutathione 1.2mmol / L;

[0046] 2) Post-harvest treatment: remove the stalks of the harvested shiitake mushrooms, and heal them in a ventilated environment at 16°C for 2.5 hours, so that the surface of the mushrooms can dissipate the field heat and keep them dry;

[0047] 3) Immediately put the shiitake mushrooms in the fresh-keeping film after the wound treatment, without tying the bag, put them in the basket, and then send them to the fresh-keeping store for pre-cooling to 8°C;

Embodiment 3

[0061] A composite fresh-keeping method of Grifola frondosa, comprising the following steps:

[0062] 1) Pre-harvest treatment: During the period from fruiting to harvesting of Grifola frondosa, spray the compound liquid twice on the mushroom body, and the last spraying time is three days before harvesting. The specific composition of the compound liquid is as follows: calcium gluconate The mass fraction is 0.8%, calcium lactate 1.3%; antioxidants are ascorbic acid 0.5mmol / L, salicylic acid 0.6mmol / L;

[0063] 2) Post-harvest treatment: remove the stalks of the harvested Grifola frondosa, and heal them in a ventilated environment at 10°C for 2 hours, so that the surface of the bacteria can dissipate the field heat and keep it dry;

[0064] 3) Immediately put the Grifola frondosa frondosa after the wound treatment into the plastic wrap without tying the bag, put it into the basket and send it to the fresh-keeping store for pre-cooling to 6°C;

[0065] 4) Stop refrigeration, pu...

Abstract

The invention belongs to belongs to the technical field of storage and preservation of agricultural products, and particularly relates to a novel composite preservation method of edible fungi. The novel composite preservation method comprises the following steps: from the fruiting period to the harvesting period of the edible fungi, spraying compound liquid onto mushroom bodies twice, wherein thelast spraying time is three days before harvesting; after harvesting, performing callus treatment to the edible fungi, then putting into preservative films, sending into a cold storage for pre-cooling, fumigating by using ethanol and a cyclopropene ethylene inhibitor, bagging, and then performing low-temperature storage, wherein during storage, the humidity of a preservative storage is higher thanor equal to 85%. By the novel composite preservation method, the storage quality and the microbial infection resistance of the edible fungi can be improved and browning of the edible fungi can be effectively inhibited; the novel composite preservation method is especially applicable to preservation of six types of edible fungi, namely oyster mushroom, shiitake mushroom, grifola frondosa, stropharia rugosoannulata farlow, pleurotus eryngii and morchella vulgaris, and is a safe and efficient novel edible fungus preserving method.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation of agricultural products, and in particular relates to a novel composite preservation method for edible fungi. Background technique [0002] my country is a big producer of edible fungi with abundant resources. According to statistics, the output of edible fungi in my country ranks first in the world. At the same time, in the domestic planting industry, edible fungus is second only to grain, cotton, oil, vegetables, and fruits, ranking sixth, and it is a new growth point and pillar industry of my country's planting industry. Edible fungi are rich in nutrients and delicious in taste, containing a variety of polysaccharides, amino acids, minerals, vitamins, etc. Some studies have shown that edible fungi also have immune regulation, anti-tumor, and anti-viral functions. However, due to the high water content of the fruiting body, the surface tissue is fragile, the lack of effective ...
