Problems solved by technology

But straw mushroom is the most difficult to preserve among other mushrooms. Its respiration is stronger than other mushrooms, and its water content is extremely high. Generally, it can only be preserved for 1-2 days, and straw mushroom cannot be stored in the same way as other mushrooms. At low temperature, the protease activity of straw mushroom is higher at low temperature, and the mycelium of straw mushroom is prone to autolysis at low temperature, while the fruiting body is severely browned, liquefied, softened and other symptoms, whi

Embodiment Construction

[0021] Below in conjunction with specific embodiment, further illustrate the present invention.

[0022] Embodiment case one:

[0023] Harvesting: Use the same batch of straw mushrooms with the strain V23 and must not spray water before harvesting. The water content of the straw mushrooms sprayed with water increases, which will cause the water to evaporate and cause liquefaction. The maturity requirements after harvesting are consistent, and the color and size are uniform. And try to avoid mechanical damage caused by harvesting, and there are no pests and diseases.

[0024] Packing: Straw mushrooms should be packed quickly after harvesting. They should be packed in PP trays with specifications of 165×115×45mm. Avoid contact between the mushroom body and the film, otherwise the contact between the water on the film and the mushroom body will easily breed microorganisms. Then use a 1.3mm pinhole to punch 6 pieces vertically and uniformly. During the punching process, mechanic...

Abstract

The invention discloses a method for keeping straw mushrooms fresh. The method comprises the following steps: selecting straw mushrooms which are commonly used in the market, have the same maturity, are picked at the same time, not watered before picked and required to be uniform in color and size, and have no disease or injury; packing the straw mushrooms with a pallet with the height of 40 mm and polyvinyl and polyvinyl-chlorid film with the thickness of 10 to 12 Mu.m after picking; then, punching 4 to 12 pin holes with the diameters of 1.3 mm and ensuring that the film is not in contact with the mushroom bodies; and storing the packed straw mushrooms at the temperature of 15 DEG C. By adopting the method, the storage period of straw mushrooms can be prolonged obviously. The invention achieves the purpose that straw mushrooms are stored and kept fresh through a simple principle, can achieve effective fresh-keeping effect without irradiation and chemical treatment, and has the advantages of nontoxicity, safety and low cost.

Description

Technical field: [0001] The invention proposes a fresh-keeping method for the harvested straw mushrooms, specifically, adopting a tray-coated and perforated packaging method for the harvested straw mushrooms. Background technique: [0002] Straw mushroom, also known as orchid mushroom, orchid mushroom, is widely grown in tropical and subtropical regions. It is one of the main export mushroom species in my country. It is cultivated in South Korea, Japan, the Philippines, Indonesia, Singapore, Thailand and India. Straw mushrooms are high-temperature mushrooms, so they are widely distributed in southern my country. Straw mushroom is a high-quality mushroom species among edible fungi. It is rich in protein, with delicate meat and delicious taste. The protein of straw mushroom contains 17 kinds of amino acids, including 8 kinds of amino acids necessary for human body. The protein content of straw mushroom is 30.1% in dry matter Compared with other mushrooms, the protein content ...
