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: Weigh 95% cottonseed hulls and 5% lime by weight, add lime and water and stir evenly, pour the dissolved lime water evenly on the cottonseed hull material pile, stir fully, add enough Measure the water to fully moisten the cottonseed hulls and adjust the water content to 65%; measure the pH value with pH test paper and 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 compost into the cultivation basket, and the thickness of the cultivation compost 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 pack...

Embodiment 2

[0038] (1) Preparation of cultivation material: Weigh 95% cottonseed hulls and 5% lime by weight, add lime and water and stir evenly, pour the dissolved lime water evenly on the cottonseed hull material pile, stir fully, add enough Measure the water to fully wet the cottonseed hulls, adjust the water content to 62%; measure the pH value with pH test paper, adjust the pH value to 9; naturally ferment for 5 days to complete the preparation of straw mushroom cultivation materials.

[0039] (2) Pasteurization: Put the fermented straw mushroom culture material into the cultivation basket, and the thickness of the cultivation material is 12cm. Close the door of the fruiting room, and pasteurize it by heating with briquettes. When the temperature of the compost in the mushroom room reaches 63°C, keep it for 9 hours.

Abstract

The invention relates to a fresh-keeping method of straw mushrooms, comprising: (1) moving the prepared straw mushroom cultivation material to a mushroom house, and performing pasteurization; (2) inoculating the straw mushrooms on the cultivation material, and Cultivate under dark conditions for 5-8 days, spray 5-25% mannitol solution on the material surface as "fruiting water"; (3) harvest straw mushrooms when they reach the egg-shaped stage, and place them at 3-6°C Just store it. The invention can significantly improve the fresh-keeping effect of the straw mushroom, has the advantages of simple operation and low cost, is suitable for production and storage of the straw mushroom, and is convenient for practical popularization and application.

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] Straw mushroom scientific name Volvariella volvacea (Bull.ex.Fr.) Sing, English name Straw mushroom or Chinese mushroom, has another name called Chinese mushroom, delicious baojiao mushroom, etc. It is recorded as Nanhua mushroom, Gong mushroom, etc. in ancient documents. China is the birthplace of artificial cultivation of straw mushrooms. As early as the 18th century, monks at Nanhua Temple near Shaoguan in northern Guangdong Province, China began to cultivate straw mushrooms. Later, overseas Chinese spread the cultivation technology to Japan, Korea, Singapore, the Philippines, Thailand, and 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 mushrooms in the world...
