Agaricus blazei is a medium-high temperature variety, the mycelium growth temperature range of 10 °C to 37 °C, fruiting body growth and development temperature range of 10 °C to 30 °C. The best sowing time for spring planting is between clear and rainy seasons. The mushroom production period is May to July, and it is one of the most suitable strains for cultivation in the late spring and early summer.
First, raw materials are prepared. Each cultivation of 200 square meters requires straw or wheat straw 2500kg, dry cow dung powder 1500kg, gypsum powder 40kg, calcium carbonate 40kg, superphosphate 20kg, urea 20kg, lime 40kg, (if there is mixed wood, you can add 500kg better), bacteria 7 species (20 species of original species and 800 varieties of cultivars were rapidly cultivated using multi-point inoculation). The above-mentioned production area and raw materials can produce 100 kilograms to 150 kilograms of dried mushroom, earn 1 million yuan for a l.5 million, and the cost investment is about 500 yuan.
Second, raw material processing. After the mixture of cow dung and sawdust is mixed with dripping water, rice and wheat straw are soaked in the ditch or pool for 24 hours. When building a stack, first lay a layer of grass 20cm thick, 1.5 meters wide, 5 meters long and 7 meters long, and then cover a layer of 3cm a 4cm thick cow dung powder, evenly spread on the grass in equal parts - lime Powder, sprinkle a layer of urea on the cow dung, and build a heap to reach a height of 15 meters. The top layer is covered with cow dung. The piles are vertically arranged around the top, and the turtles are piled on top and covered with rain. Turning the stack: Under normal circumstances, the stacking temperature can be increased to more than 65°C after the construction of the stack for 2 days. When the temperature in the stack rises until the highest peak begins to fall, it must be turned in time. The turning method is to turn the upper layer down, the outer layer is turned to the inner layer, and the upper and lower sides are exchanged with each other, so that the culture material reaches maturity and uniform. The first time the stack is turned, the gypsum powder, calcium superphosphate, and the second turnover are layered. Add calcium carbonate and turn it four times in turn. Pay attention to replenishment each time you turn the stack and adjust the moisture content in the material. The number of days between rollovers is approximately 7, 6, and 3 days, and the total fermentation period is approximately 20 days and 21 days.
Third, mushroom shed, bed settings. Agaricus blazei is generally cultivated in Daejeon single bed. Above the cultivation field, a four-yang shade awning should be erected, about 2 meters high, similar to the shiitake mushroom shed. If cultivating in citrus or grape orchards, there is no need for arbours. Mushroom bed width 1 meter, 15Cm high, length is limited to the venue.
Fourth, sowing, earth covering. The composted fermented material is dark brown, free from ammonia gas and odor, elastic, and has a water content of 60%. When the feed temperature drops to 28°C, it must be sowed in time. Material thickness 20cm, uniform thickness, 4 bags per square meter, according to 10cm x10cm spacing acupuncture seeding, hole depth 3cm. Leave a small amount of bacteria to sow the material surface and compact the material. The close contact between the material and the species facilitates the germination and colonization of mycelium and the growth of the feed. The surface is covered with moisturizing bacteria. Sowing for 15 days to 18 days: The surface of the six hyphae has been connected, the material has grown to 2/3 when the mycelium began to cover the soil. Cover soil with paddy soil, large soil diameter 2cm; small soil diameter of about 0.5cm. Lime water was used to preheat the soil to Tianbaixin three days before the cover soil. Cover the earth first, cover the small soil, and cover the soil with a total thickness of 3.5cm.
Fifth, management, harvesting. From sowing to mushrooming at normal temperatures - it generally takes 35 days to 40 days. Hyphae should pay attention to heat preservation and keep fresh air. The relative humidity of the air is controlled at 60% to 75%, and the water content of the culture material is controlled at 55% to 65%. After sowing, the material surface is generally not directly sprayed with water. The temperature is controlled at 20-27. Each morning and evening, the film is ventilated once every half hour to 1 hour. The fruiting period should be kept warm and temperature controlled, 18 °C to 27 °C is the best. Increase the amount of ventilation, covering the soil moisture content of 55% -60%, the relative humidity of air is maintained at 85% -90%, and often spray water according to the amount of mushrooms. Keep the air fresh in the field so that the fruit body grows and develops normally. Agaricus blazei is expensive and costs 100 yuan to 150 yuan per kilogram of dry goods. When the mushroom cover begins to grow outwards and the pellicle does not break off from the stipe, it can be picked. After picking, cut the clay, wash scales, dehydrate and dry timely, store in grades for sale.
The main functions of sweeteners in food are as follows [2]:
(1) Taste: Sweetness is one of the indicators of many foods. In order to make food and beverages taste palatable, a certain amount of sweetener needs to be added.
(2) For the adjustment and enhancement of flavor, sweetness is generally required in cakes; in beverages, there is a "sugar-acid ratio" for flavor adjustment. Sweeteners allow products to achieve good flavor while retaining fresh flavor.
(3) The formation of flavor, sweetness and the flavor of many foods are complementary to each other, and the flavor of many products is produced by the combination of flavor substances and sweeteners, so many foods are added with sweeteners.
Food additives sweeteners Neotame, Sucralose
