Problems solved by technology

After the fruiting bodies of straw mushrooms are stored at conventional low temperature for a period of time, water seepage, browning, and rot appear on the surface. This characteristic severely limits the circulation of fresh straw mushrooms and their low-temperature refrigeration and preservation, which in turn affects foreign exchange earnings from exports. The development of the straw mushroom industry in China and even in the world, so the preservation of straw mushrooms has become a technical problem to be solved urgently in the development of the industry

Embodiment 1

[0027] (1) Preparation of cultivation material: take by weight 95% cottonseed hulls and 5% lime, add water to the lime and stir evenly, pour the dissolved lime water evenly on the cottonseed hull stockpile, fully stir, add enough Measure water to fully wet the cottonseed hulls, adjust the water content to 65%; measure the pH value with pH test paper, adjust the pH value to 10; naturally ferment for 3 days to complete the preparation of straw mushroom cultivation materials.

[0028] (2) Pasteurization: put the fermented straw mushroom culture material into the cultivation basket, and the thickness of the cultivation material is 10cm. Close the door of the fruiting room, and heat it with briquettes for pasteurization. When the temperature of the compost in the mushroom room reaches 65°C, keep it for 8 hours.

[0029] (3) Vaccination. Start inoculation when the temperature in the mushroom house drops to 33°C. Spread the V23 strains of straw mushrooms full of bacteria packets ev...

Abstract

The invention relates to a fresh-keeping method of straw mushrooms. The method comprises the steps that 1, a prepared straw mushroom cultivation material is moved into a mushroom house and subjected to pasteuring; 2, the straw mushrooms are transplanted to the cultivation material and cultivated for 5-8 days under the dark condition, and a mannitol solution of 5%-25% serves as fruiting water to be sprayed on the material surface; 3, after the straw mushrooms grow to the egg-shaped period, harvesting is conducted, and the harvested straw mushrooms are stored at 3-6 DEG C. The fresh-keeping method of the straw mushrooms can significantly improve the fresh-keeping effect of the straw mushrooms, has the advantages of being easy and convenient to operate, low in cost and the like and is suitable for production and storage of the straw mushrooms, and practical application and popularization are convenient.

Description

technical field [0001] The invention belongs to the field of straw mushroom cultivation, in particular to a fresh-keeping method of straw mushrooms. Background technique [0002] The scientific name of straw mushroom is Volvariella volvacea (Bull.ex.Fr.) Sing, and the English name is Strawmushroom or Chinesemushroom. China is the birthplace of artificial cultivation of straw mushrooms. As early as the 18th century, the monks of Nanhua Temple near Shaoguan in northern Guangdong Province, China began to cultivate straw mushrooms. Later, overseas Chinese spread the cultivation technology to Japan, South Korea, Singapore, the Philippines, Thailand, In Malaysia, India, Indonesia and other places, some European and American countries have also begun to cultivate in recent years, but China is still the main cultivation country of straw mushroom in the world. Straw mushrooms are delicious and nutritious. Fresh straw mushrooms contain about 92% water, about 3% protein, and about 2%...
