Method for keeping picked straw mushrooms fresh

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 ...

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, which greatly affect the quality. Therefore, studies have shown that straw mushroom The optimum temperature is 15°C

[0004] At present, there are quick-freezing fresh-keeping methods, film-modified atmosphere fresh-keeping methods, irradiation fresh-keeping methods, ozone treatment fresh-keeping methods, microwave oven treatment fresh-keeping methods, etc., but the above fresh-keeping methods all have different degrees of price and safety problems, especially Irradiation preservation and chemical preservation have different levels of toxicity
