Key points of fresh-keeping technology of mushroom
The main factors affecting the preservation of mushrooms are as follows: temperature: the higher the temperature, the worse the preservation of mushrooms. 0-4 ℃ is the suitable temperature for mushroom preservation. In addition to quick freezing, freezing injury is easy to be caused when the temperature is less than 0 ℃. Water quality: when the content of iron or copper in the water is more than 2 mg / L, the mushroom color darkens and turns brown, so iron and copper utensils and tools are prohibited. Humidity: 95-100% required. Less than 90% of the color darkens and it is easy to open an umbrella and deteriorate. Gas composition: it contains important causes of decay, which can be inhibited by sterilization and adjusting pH value. Enzyme activity

Vegetative Storage and Preservation of Tea Plant
The direct preservation of tea plant nutrients in the field requires a lot of land and labor, so the long-term preservation techniques of tea roots, seedlings, seeds and pollen were studied. The preservation of roots is to sterilize the lignified roots before spring germination and store them in plastic bags together with sterilized semi-dry soil or water moss in an environment of 1-5 ℃. After 7 years of preservation, the number of adventitious buds can be up to 70%. The roots could still be regenerated after 6 years storage at 1 ℃. The consumption of carbohydrates in root tissue after preservation at low temperature

Preservation Technology of Edible Fungi
Strain is not only the main biological resources, but also the primary means of production for the production of edible fungi. After a good strain has been selected and bred, its excellent characters must be kept unchanged or changed slowly as little as possible, so that the production performance will not be reduced and can be used in production for a long time. Therefore, the preservation of strains is of great significance in the production of edible fungi. First, the principle of strain preservation there are many methods of strain preservation, but the principle is more or less the same. First of all, good purebred should be selected. The use of spores, spores and nutrients of microorganisms; secondly, according to their physiology and biochemistry

A New method of Preservation and Preservation of Fish
Fresh fish has a new method of anticorrosion, Moscow Meat and Milk Industry Research Institute of Russia has developed the use of glycerol spraying method to prolong the preservation time, so that the stored fresh fish to maintain the original flavor. The new technology of glycerol spraying is formulated as follows: glycerol 1% Mel 20%, hydroxyethylamide 0.15% Mel 0.3%, sorbic acid 1% Mel 5%, polyvinyl alcohol 0.3% Mel 30%, and the rest is water. Spraying the preservative on the fish can slow down the oxidation and realize long-term fresh-keeping.

Preservation of edible mushroom strains
Usually take the following two methods of preservation: slope low temperature preservation method. This is the simplest preservation method, that is, the vigorous and pollution-free slant test tube is put in the refrigerator and preserved at a low temperature of 4 ℃ ~ 6 ℃, and then transferred to the fresh slant medium every 2 to 3 months, and then preserved after culture. The other is liquid paraffin preservation. This method is to inject sterilized liquid paraffin in the aseptic room in the inclined test tube to be preserved, and it is appropriate to inject wax 1 cm higher than the inclined surface. Then plug it with a cork or rubber.

Mushrooms were rinsed with 0.01% sodium metabisulfite solution for 35 minutes, then soaked in 0.1% sodium metabisulfite solution for half an hour, taken out, drained, and stored in plastic bags. The preservation effect was better at room temperature of 1015℃.
