Key Technical Points and Detailed Methods for Salt-Preserving Fresh Mushrooms
1. Mushroom selection: Mushrooms to be salt-preserved should be harvested at the right time, cleaned of impurities, and any diseased, pest-damaged, or moldy specimens removed. For button mushrooms (Agaricus bisporus), the caps should be intact and the base of the stem trimmed off; for oyster mushrooms (Pleurotus ostreatus), the clustered fruiting bodies should be separated one by one and deformed mushrooms discarded; for lion's mane (Hericium erinaceus) and nameko (Pholiota microspora), the aged stipes should be cut off. Harvest and process on the same day; do not leave overnight. 2. Rinsing: First wash off dirt and other impurities from the surface of the mushrooms with a 0.6% salt solution (too strong a solution will turn the mushrooms red), then rinse with a citric acid solution (pH 4.5)

Many Methods for Preserving Edible Mushrooms: Master the Techniques to Extend Storage Life
Salt preservation: Freshly harvested oyster mushrooms, Phoenix-tail mushrooms and the like, after being cleaned up, are soaked in 0.6% salt water for about 10 minutes, then taken out, drained and stored in plastic bags, keeping fresh for 5-8 days. Rice-water film preservation: Add 1% soda ash or 5% baking soda to rice water, stir well, and cool to room temperature. Soak freshly picked mushrooms in the rice water, take them out after 5 minutes, and dry them in a cool, dry place; by then a thin film of rice water will form on the surface of the mushrooms, which can isolate air, and the mushrooms can generally keep fresh for 2-3 days.

Methods and Technical Key Points for Preserving Edible Mushroom Spawn
1. Distilled water method. Suitable for the spawn of oyster mushroom, enoki mushroom, and shiitake mushroom. 1. Preserving oyster mushroom and enoki mushroom spawn. First, move the test-tube spawn that is at the eight-tenths mature stage and awaiting preservation into an inoculation box, and after sterilization, use a medical syringe to inject distilled water through the test-tube stopper until the entire surface of the culture medium is submerged, up to 2 cm from the tube mouth. Seal the tube mouth with mineral wax, and at normal temperature place it upright in a cool, shady place, where it can be preserved for 1-1.5 years. 2. Preserving shiitake mushroom and wood ear mushroom spawn. Use a 150 x 15 mm finger-shaped tube to place solid or

Methods and Key Techniques for Preserving Edible Mushroom Strains
Two methods are usually used for preservation: the slant low-temperature preservation method. This is the simplest preservation method, in which vigorously growing, uncontaminated slant tubes are placed in a refrigerator and preserved at a low temperature of 4°C~6°C, after which they are subcultured onto fresh slant medium every 2~3 months and, after incubation, preserved again. The other is the liquid paraffin preservation method. In this method, sterilized liquid paraffin is injected in a sterile room into the slant tubes to be preserved, with the paraffin added to a level 1 cm above the slant. Then a wooden stopper or rubber

Simple and Practical Methods for Preserving Edible Mushroom Spawn
While domesticating the wild-cultivated oyster mushroom variety "1015", we subjected the strains to salt-tolerance training. This involved salinizing ordinary PDA medium to prepare a solution at a concentration of 1.0%-1.5%, sterilizing it under high pressure for 45-60 minutes, cooling it to make slants, inoculating under sterile conditions, and culturing in an incubator. After the cultures matured, every 10 tubes were grouped together, placed in polyethylene bags, and stored at room temperature for 9 months before subculturing. The survival rate reached over 95%,

Energy-saving and heat-preserving methods for winter cultivation of oyster mushrooms
In winter, when temperatures are low, cultivating oyster mushrooms often results in slow mycelial growth or no growth at all, and even if mushrooms do form, they may be deformed. Heating with coal stoves is costly and can easily cause poisoning symptoms in the mushrooms. The following measures make full use of biological heat to keep the mushroom bags at a relatively high temperature for mycelial growth, which can save cultivation costs. If oyster mushrooms are bagged and inoculated in autumn, by the time the weather turns cold, half the bag will have well-developed mycelium. Keeping such bags warm during cultivation allows the mycelium to quickly fill the entire bag. For those not bagged and cultivated in advance, heating can be applied all at once.

What are the methods for storing and preserving mushrooms?
The main factors affecting mushroom preservation are as follows: Temperature: the higher the temperature, the worse the preservation of mushrooms. 0-4°C is the suitable temperature for mushroom preservation. Apart from quick freezing, temperatures below 0°C can easily cause freezing damage. Water quality: when the iron or copper content in water exceeds 2 mg/L, the color of mushrooms darkens and turns brown, so iron and copper utensils and tools are prohibited. Humidity: 95-100% is required. Below 90%, the color darkens and the caps tend to open and spoil. Gas composition: an important cause of spoilage, which can be suppressed by sterilization and adjusting the pH value. Enzyme activity: polyphenol ox
