Edible fungus should master the following technologies during the picking process:
First, master the best harvest period. All kinds of mushroom ears basically have a beautiful appearance, fresh color, and good taste at the time of maturity in July and July. Taking mushrooms as an example, seventy-eight mature signs, pellicles have been broken, the cap has not yet fully developed, there is still a little inward, forming a "copper rim", the pleats have all stretched, from white to tan or dark brown . This is the harvest time of mushrooms. The shiitake mushrooms harvested in due course have bright color, strong flavor, thick caps, soft and tough meat, high commodity value, expired harvesting, full development of mushroom umbrellas, thin meat, long feet, and discoloration of bacteria pleats. At this time, its weight is reduced. Low commodity value.
Second, pay attention to picking technology. Mushrooms (mushrooms, mushrooms, straw mushrooms, etc.) harvested must be kept large and small. When the mushroom is plucked, the thumb and forefinger pinch the base of the mushroom stalk, rotate it left and right, and then gently lift it upwards. Do not bump the surrounding mushroom buds. Do not allow the mushrooms to remain on the fungus tube. . If the mushroom grows densely and the base is deep, use a small pointed knife to dig it up from the base of the mushroom. When picking, prevent damage to the surface of the bacterial bed or bacteria. For colloidal fungi such as white fungus, black fungus, and clustered oyster mushrooms, enoki mushrooms, etc., use a knife to cut off the entire crop from the base at the time of harvest, taking care to keep the flower shape intact.
Third, choose suitable weather. Harvesting on sunny days is conducive to processing, and it is generally not used on cloudy or rainy days. The reason is that high water content makes it difficult to dry and affect quality.
4. Fresh mushrooms that are harvested should be packed in small baskets or small baskets, and they should be handled with care to maintain the integrity of the bodies and prevent them from crushing and damaging rings, which will affect the quality. The fresh mushrooms that are harvested should be separated according to the size of the mushroom body and the blossoming quality, and they should not be mixed together. Then, they should be loaded in different containers for processing.
Fifth, stop the water temperature control before mining. As a fresh-keeping outlet or dehydrated product, it must be drained or dehydrated during processing. If water is sprayed before harvesting, the body of the mushroom will have a high moisture content, and when the fresh mushroom is processed, the pleats will turn brown, and when the dehydration is dried, the pleats will turn black, and the product does not meet the export requirements. If it is sold domestically, the mushroom body will be too moldy if it is too watery.
There are many kinds of chemical raw materials and they are widely used. There are five to seven million chemicals in the world, and more than 100,000 chemicals are sold in the market. More than 1,000 new chemicals are produced every year, and 150 to 200 of them are considered carcinogens.Chemical raw materials can be divided into organic chemical raw materials and inorganic chemical raw materials.Folding organic chemical raw materials
They can be classified as alkanes and their derivatives, alkenes and their derivatives, alkynes and their derivatives, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydrides, esters, organic acids, carboxylate, carbohydrates, heterocycles, nitrile, halogenates, aminoacyls, and others
Folding inorganic chemical raw materials The main raw materials of inorganic Chemical Products are sulfur, sodium, phosphorus, potassium, calcium and other chemical minerals (see inorganic salt industry), coal, oil, natural gas, air, water and so on. In addition, many byproducts and wastes of industrial sectors are also raw materials of inorganic chemical industry, such as coke oven gas in the coking production process of the iron and steel industry, which contains ammonia can be recycled into ammonium sulfate with sulfuric acid, and sulfur dioxide in the smelting waste gas of chalcopyrite, galena and sphalerite can be used to produce sulfuric acid.
