Mushroom preservation technology Mushroom preservation methods include: Modified atmosphere preservation, cryogenic preservation, radiation preservation, and salt water preservation. The methods are:
Modified atmosphere preservation: using simple atmosphere storage, in 3 to 5 days can keep mushrooms fresh without umbrellas, basically no browning, water loss rate of less than 1%. At present, air-permeable plastic film bags are generally used. The oxygen concentration in the bag is maintained at 1%, and the carbon dioxide concentration is 10% to 15%, which allows the mushroom to maintain whiteness and freshness within 4 days.
Cold preservation: low temperature can maintain the quality and quality of mushrooms. During storage, the temperature is maintained at 0-3 degrees and the relative humidity is 90%-95%.
Quick-freezing and fresh-keeping: In 30 to 40 minutes, the mushroom will be reduced from normal temperature to -40 degrees to -30 degrees, and then frozen at -18 degrees to maintain the original quality and flavor for a long time.
Salt water preservation: The hot-cooked mushrooms are immediately placed in 19-wave culinary salt solution. Several days later, an appropriate amount of salt is added to maintain the 19-wave culinary salt solution. After 4 to 6 days, the weight and pH are stable when the fresh water is sealed. .

The dehydrating vegetable products that are free of preservatives and chemicals, high in nutrient content, and have an improved taste and appearance is disclosed. whole, raw vegetables are first precooked with hot air for about 4 to about 8 hous. The vegetables are then dehydrated in the temperature range of about 80° C. to about 122° C. to a moisture content of less than 8%.It is easy to use and easy to store.
