Recently, the "Straw-based material to replace sawdust with high-efficiency and high-yield technology for industrial three-dimensional cultivation of shiitake mushrooms" researched and invented by researcher Sun Zhiguo, the legal person of Beijing Edible Fungus Research and Development Co., Ltd., was successfully tested and demonstrated in Hiraizumi.
This technology uses lignin-rich corn stalks, bean stalks, cotton stalks, sunflower stalks, corn cobs, etc. to replace sawdust as the base material for cultivating shiitake mushrooms, which can reduce the amount of sawdust used for cultivating shiitake mushrooms by 10%-18% (usually The lignin content in the production of wood-rot edible fungi needs to reach 40%-45%, and the lignin content in the production of mushrooms using the new technology invented by Sun Zhiguo is only required to reach 25%-35%. The insufficient lignin concentration is supplemented by the lignin in the straw) , Which not only saves forest consumption, but also reduces straw burning, which plays an important role in protecting forest resources and improving the atmospheric ecological environment.
At the same time, the use of rectangular monolayer membrane sterile peroxidized fermentation bacteria bag with nano-breathing holes in cultivation instead of the long cylindrical double membrane sterile anaerobic fermentation bacteria bag currently used has multiple advantages: one is the rectangular parallelepiped bacteria bag The five sides can produce shiitake mushrooms. Compared with the lower surface of the longer cylindrical bacteria bag in contact with the carrier, the mushrooms cannot be produced. The surface area of ​​the mushrooms is greatly increased, so the yield of mushrooms is high; the second is that the nano-breathing holes can realize full-oxygen fermentation and mycelium Fermentation time is accelerated. Generally, the fermentation time of cuboid mycobacteria with breathing openings takes about 20 days, while the development of the long cylindrical mycelium used in conventional cultivation takes 3 to 4 months, and the production efficiency of mushrooms is improved by 3 ~5 times; third, the rectangular rods with nano-breathing holes do not need to use the bag punch (machine) to perforate the surface of the bacteria bag like the long cylindrical rods used in conventional cultivation, which saves the cost of production; Rectangular single-layer membrane bacteria bag is longer and cylindrical double-layer membrane bacteria bag saves film, which is beneficial to reduce the white pollution caused by discarding waste bacteria bag; Fifth, the three-dimensional cultivation of cuboid mushroom sticks occupies more space than conventional long cylindrical mushroom sticks. Greatly reduced, in the case of the same land area, the number of cuboid industrial three-dimensional cultivation of mushroom sticks is more than three times the production benefit of conventional cultivation of mushrooms. The cuboid mushroom bagging machine, which is matched with the new technology of "straw base material instead of sawdust in factory-based three-dimensional cultivation of mushrooms and high-efficiency production technology", has been popular with mushroom farmers after nearly two years of use, and the bagging efficiency has been greatly improved.
Straw replaces sawdust as base material, cuboid fungus bag with nano breather and cuboid fungus bagging machine supporting technology, not only suitable for shiitake mushrooms, but also suitable for the cultivation and production of many wood-rot edible fungi such as Pleurotus eryngii and Pleurotus eryngii At the same time, it also has an important reference for the cultivation of some grass-rot edible fungi. In the future, as the country will use straw as a base material for edible fungi, comprehensive utilization of agricultural and forestry crop straw support will increase, and mushroom cultivation of edible fungus rods will use traditional long cylindrical rods to produce high-volume and efficient mushrooms with nano-respiration. The rapid natural change of the rectangular parallelepiped fungus sticks will inevitably promote the rapid corresponding changes in the edible fungus raw material formula and production technology and equipment. It is foreseeable that China will bring a revolution in edible fungi cultivation and production technology in the next few years, especially wood rot. A big and profound revolution in the cultivation and production technology of edible fungi.

Lycopene, a carotenoid found in plant foods, is also a red pigment. Dark red acicular crystal, soluble in chloroform, benzene and grease but insoluble in water. Unstable to light and oxygen, turning brown when met with iron. Molecular formula C40H56, relative molecular mass 536.85. The molecular structure has 11 conjugated double bonds and 2 unconjugated double bonds, constituting a straight chain type hydrocarbon. It does not have the physiological activity of vitamin A, but it has strong antioxidant function. The content is higher in the fruits of mature red plants, especially in tomato, carrot, watermelon, papaya and guava. It can be used as pigment in food processing and as raw material of antioxidant health food.
