Embodiment 1

[0019] A modified atmosphere fresh-keeping method for winter sun sun, which is to place winter sun fruit bodies in a PE modified atmosphere fresh-keeping bag together with pre-packaged gas adsorbents, remove the air in the fresh-keeping bag, and seal the mouth of the bag Tie it tightly, and store the fresh-keeping bag in the refrigerator. The gas adsorbent is composed of a deoxidizer, an ethylene adsorbent and a carbon dioxide remover.

[0020] The deoxidizer is made by weighing iron powder, sodium hydroxide, sodium sulfite, and activated carbon in a mass ratio of 8:3:1:0.5, mixing them uniformly, and putting them into composite non-woven packaging bags for use.

[0021] The average particle diameter of the components of the deoxidizer is 2.5mm.

[0022] The ethylene adsorbent is prepared by immersing activated carbon in 4% potassium permanganate solution, stirring with a magnetic stirrer for more than 2 hours, removing and draining, and putting it into a composite non-woven p...

[0029] A modified atmosphere fresh-keeping method for winter sun sun, which is to place winter sun fruit bodies in a PE modified atmosphere fresh-keeping bag together with pre-packaged gas adsorbents, remove the air in the fresh-keeping bag, and seal the mouth of the bag Tie it tightly, and store the fresh-keeping bag in the refrigerator. The gas adsorbent is composed of a deoxidizer, an ethylene adsorbent and a carbon dioxide remover.

[0030] The deoxidizer is made by weighing iron powder, sodium hydroxide, sodium sulfite, and activated carbon in a mass ratio of 12:7:3:1.5, mixing them uniformly, and putting them into composite non-woven packaging bags for use.

[0031] The average particle diameter of the components of the deoxidizer is 3mm.

[0032] The ethylene adsorbent is prepared by immersing activated carbon in 8% potassium permanganate solution, stirring with a magnetic stirrer for more than 2 hours, removing and draining, and putting it into a composite non-woven pa...

Embodiment 3

[0039] A modified atmosphere fresh-keeping method for winter sun sun, which is to place winter sun fruit bodies in a PE modified atmosphere fresh-keeping bag together with pre-packaged gas adsorbents, remove the air in the fresh-keeping bag, and seal the mouth of the bag Tie it tightly, and store the fresh-keeping bag in the refrigerator. The gas adsorbent is composed of a deoxidizer, an ethylene adsorbent and a carbon dioxide remover.

[0040] The deoxidizer is made by weighing iron powder, sodium hydroxide, sodium sulfite, and activated carbon in a mass ratio of 10:5:2:1, mixing them evenly, and putting them into composite non-woven packaging bags for later use.

[0041] The average particle diameter of the components of the deoxidizer is 2.8mm.

[0042] The ethylene adsorbent is prepared by immersing activated carbon in 6% potassium permanganate solution, stirring with a magnetic stirrer for more than 2 hours, removing and draining, and putting it into a composite non-woven...

Abstract

The invention relates to the field of preservation of edible mushrooms, particularly a modified atmosphere packaging method of Phallus impudicus. The method comprises the following steps: pretreating Phallus impudicus sporophores, putting the pretreated Phallus impudicus sporophores and a gas adsorbent which is previously independently packaged into a PE (polyethylene) modified atmosphere packaging bag, removing air in the packaging bag, tightening the bag opening, and storing the packaging bag in a refrigerator. The method is capable of effectively adjusting the gas composition in the Phallus impudicus sporophore storage system, inhibiting the ethylene from generation, preventing the overhigh carbon dioxide concentration from causing poisoning, lowering the respiratory intensity of Phallus impudicus and effectively inhibiting the Phallus impudicus sporophores from browning and sensory quality deterioration, well keeps the nutrition and flavor, has favorable preservation effects on the Phallus impudicus sporophores, has the advantages of no chemical preservative residues, no influence on the mouthfeel and flavor, higher eating safety and low investment, is simple and convenient to operate, generates high economic value, is a practical technique for promoting income increase of Phallus impudicus farmers and culture enterprises, and thus, has higher popularization and application value.

Description

technical field [0001] The invention relates to the field of fresh-keeping of edible fungi, in particular to a method for keeping fresh of winter scallions by controlled atmosphere. Background technique [0002] Dongsun, scientific name Phallus inpudicus L.ex.Pers., also known as Phallus inpudicus L.ex.Pers., also known as Phallus inpudicus L.ex.Pers. It is a rare and precious edible fungus unique to the mountains and forests of other places. It has extremely high edible value and medicinal value. As food, it is high in protein, low in fat, rich in nutrition, delicious in taste and unique in flavor. " and "Chinese Materia Medica" records that its medicinal properties are sweet, light, and warm in nature. It has the effects of promoting blood circulation and relieving pain, and expelling wind and dampness. The incidence of aggregation can reduce the death of breast cancer patients due to venous thrombosis. It has the potential to assist in the prevention of nutritional produ...
