Detailed explanation of key points of mushroom preservation technology, easily extend storage time
Mushroom preservation methods include modified atmosphere preservation, low-temperature preservation, radiation preservation and brine preservation, etc. The methods are: modified atmosphere preservation uses simple modified atmosphere storage, within 3 to 5 days it can keep mushrooms fresh and tender without opening their caps, basically without browning, and with a water loss rate below 1%. At present, breathable plastic film bags are generally used for packaging, maintaining an oxygen concentration of 1% and a carbon dioxide concentration of 10% to 15% inside the bag, which can keep mushrooms white for 4 days with good freshness. Cold storage preservation: low temperature can keep mushrooms fresh and of high quality. During storage and transportation

Simple preservation techniques for oyster mushrooms help you extend storage time
Under normal conditions, oyster mushrooms are difficult to store and have a short shelf life. Two days after harvesting, oyster mushrooms lose freshness sharply due to water loss, the caps turn yellow, and an off-odor appears. During peak fruiting seasons, large quantities of fresh mushrooms flood the market at once, causing mushroom prices to plummet; on the other hand, during off-seasons and in cities far from mushroom-growing areas, there is little mushroom supply and nothing to sell. For this reason, here is a brief introduction to research on oyster mushroom storage and preservation. Method: Harvest oyster mushrooms at 80% maturity, remove diseased, insect-damaged, and damaged mushrooms, place them in a clean, cool, ventilated area, and use an exhaust fan for 1-1.5 days of air-cooling pretreatment, then

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.
