How Potato Chips and Puffed Potato Products Are Made
1. Potato chips (1) Production process: Potatoes → sorting → washing → slicing → color protection → dehydration → vacuum frying → de-oiling → cooling → sorting → packaging → finished product. (2) Key production points ① Slicing and color protection. Because potatoes are rich in starch and have a high solids content, the slice thickness should not exceed 2mm. After slicing, starch quickly exudes onto the surface of the potato slices, and browning occurs if they are left in the air too long, so they should be immediately placed in 98°C hot water for 2min-3min

Method for making homemade candied mushrooms from fresh mushrooms after picking
Process flow: material selection → pretreatment → sugar soaking → sugar boiling → baking → packaging. 1. Raw material selection: choose fresh mushrooms with medium-sized caps, natural color, intact shape, and no disease or insect spots as raw materials. 2. Pretreatment: 1. Salt water soaking: remove impurities from the harvested fresh mushrooms, immediately put them into 1%-2% salt water and soak for 4 hours-6 hours to increase the firmness of the mushroom bodies. 2. Blanching: pour the cleaned and drained mushroom bodies that have been soaked in salt water into boiling water and blanch for 7 minutes-9 minutes to destroy enzyme activity and prevent browning of the mushroom bodies. 3

Major progress made in project to control soybean yield reduction from continuous and alternating cropping
The reporter learned from relevant departments that the project "Research and Demonstration of Key Technologies for Controlling Soybean Yield Reduction under Continuous and Alternating Cropping," tendered by the Municipal Science and Technology Bureau, has achieved major progress after two years of scientific research. The project was carried out in Yilan and Bayan counties, the two counties with the largest soybean area in Harbin. Through key technology research, soybean varieties resistant to continuous and alternating cropping were selected, including Kenfeng 16, Heinong 48, Kangxian 4, and Hefeng 47. A formula fertilization technique was proposed with 45 kg of nitrogen, 60-67.5 kg of phosphorus, 67.5-75 kg of potassium, and

Key Processing Techniques for Fried Flavor Foods Made from Oyster Mushrooms
Using fresh oyster mushrooms as the raw material, fried processing can produce flavored dried oyster mushrooms and oyster mushroom nutritional oil. 1. Raw material selection: Choose fresh oyster mushrooms of suitable maturity, normal mushroom shape, free of disease spots and insect damage, and with spores not yet released as the raw material. 2. Raw material handling: Cut off the mushroom stems, quickly rinse with clean water to remove debris, drain, then use a fan to blow-dry the surface moisture. Do not soak for too long during washing; if the mushrooms absorb too much water, use a centrifugal spin dryer to remove most of the moisture. After washing, cut the raw material into mushroom strips 2 cm wide. 3. Frying: Use refined rapeseed oil; the oyster mushroom addition

How are dog meat foods made? A detailed explanation of 3 production techniques
I. Dried dog meat slices 1. Preparation of materials. Use the small pieces of dog meat trimmed off when processing other products and a small amount of pork fatback; the fat-to-lean ratio must not exceed 1:10. Cut the raw meat into strips 3 cm thick, wash and drain, and grind with a meat grinder. Do not grind the fatback. 2. Curing. For every 100 kg of raw meat, use 2 kg of salt, 4 kg of soy sauce, 8 kg of white sugar, 1.5 kg of baijiu, 200 g of monosodium glutamate, 200 g of compound phosphate, 50 g of sodium erythorbate, 50 g of nicotinamide, 5 g of sodium nitrite, and white pep

What are the common mistakes made when medicating chickens?
(1) Blindly increasing the dose: most farmers believe that the larger the dose, the better the treatment effect, and blindly use large doses when using antibiotics. With large doses, some may have a certain effect at the time, but hidden dangers are left behind. ① It causes poisoning death in broilers or chronic drug accumulation toxicity, damaging liver and kidney function. When liver and kidney function are impaired, the detoxification function of the broiler's body declines, making medication difficult during treatment and disease prevention. ② It kills the beneficial bacteria in the intestine, destroys the balance of normal intestinal flora, and causes metabolic disorders in broilers,
