What is canned mushrooms?
|Canned mushrooms are rich in amino acids and proteins and are delicious. However, the mushroom has a strong respiration after harvesting, and it quickly opens at an ordinary temperature, browning, odor, quality deterioration, and can only be stored for a short period of time. Dried mushrooms are easy to preserve, but the nutritional value is reduced, and processing is not timely and can cause serious damage. Therefore, measures should be taken before post-harvest storage, transportation, sales and processing to prevent the quality of mushrooms from declining. There are many cultivars of mushrooms, such as oyster mushrooms, shiitake mushrooms, Agaricus bisporus, Flammulina velutipes, and Pleurotus ostreatus.|
The suitable conditions for canned mushroom storage are 0 ° C and 95% relative humidity. The water loss of the mushroom is related to the black handle and the open umbrella. Packaging with a film or maintaining a relative humidity higher than 95% can reduce water loss. Modified atmosphere storage can inhibit browning of mushrooms. Controlling 2--4% oxygen and 5--10% carbon dioxide is beneficial to keep the white color of the mushroom and prolong the storage life. The heat treatment of canned mushrooms with salt water, citric acid, ascorbic acid, sulfur dioxide or steam can passivate the activity of polyphenol oxidase and prevent enzymatic browning; in storage and transportation, metal containers should be avoided to prevent non-enzymatic browning.
Canned mushrooms are ideal for natural or multi-functional foods. The most commonly eaten in the world is known as mushrooms. Further screening of domesticated high-quality production strains from wild species has great potential. China has been domesticated and artificially cultivated for the first time in the world. Mushrooms, fungus, golden ear, white fungus, straw mushroom, enoki mushroom, Hericium erinaceus, bamboo bud, tea tree mushroom, etc., have now domesticated Mongolian mushroom, and wild edible mushroom delicious cattle Hepatic bacteria, morel mushroom, red rivet mushroom, orange amanita, sticky cap boletus, red mushroom, etc. can also be collected in large quantities, and canned mushrooms are sold at home and abroad.
