Harvesting and processing of Agaricus bisporus

The timing of mushroom harvest is that the bacterial curtain is not broken, the umbrella is not opened, and reach the size of the purchase specification. Early harvest, small mushroom, low yield; too late, will inhibit the formation and growth of the next batch of mushrooms, prolong the growth cycle, but also affect the quality of mushrooms, especially when the temperature is high (about 20 ℃) and produce mushrooms for a long time, it is easy to become thin mushrooms and open umbrella mushrooms. As a commercial mushroom for processing canned mushrooms, it is generally required that the mushroom cap should be harvested in time when the diameter of the fungus cap is 2mi 4cm. It is usually harvested once a day, but at the peak of production, it should be harvested twice a day to prevent the umbrella from being opened and reduce the quality of the product. The mushrooms collected were cut off from the base of the stalk with mud and graded according to the processing standard. The grading standards vary from place to place, and there are three grades, and there is only the final meal, which is full of glue, stirs up the reef, "burning diced rice" invades the root-3.5 cm, the mushroom shape is round, and there are no flake mushrooms, umbrella mushrooms and deformed mushrooms. The color is white and there is no mechanical injury. Wormholes and spots. The fungal stalk is thick and short, with a length of 0.5ml and 0.8cm, with smooth cutting and no soil. Fresh mushrooms are crisp and tender, and they should be handled gently in the process of harvesting, chopping mushroom stalks, transportation and transportation to prevent bruising. After the mushroom body is bruised, the polyphenoloxidase and tyrosinase in contact with the air, under aerobic conditions, will make quinones and amino acids or peptides form reddish-brown compounds, affecting the appearance of mushrooms, therefore, in the process of sending to the purchase station or processing plant, the mushrooms should be wrapped in gauze or plastic film bags and placed in buckets or bamboo baskets with fillers. In transportation, vibration should be reduced as much as possible to prevent bruising.
