on February 7, Gansu Provincial Market Supervision Bureau issued the food safety tips for livestock meat and agricultural and sideline products, reminding the masses to check the inspection and quarantine certificate of inbound goods when purchasing imported meat. When purchasing frozen livestock and poultry meat, you should focus on checking whether the operating temperature of the frozen display cabinet is normal

after slaughtering and processing of live livestock (such as pigs, cattle, sheep, rabbits, etc.) and poultry (such as chickens, ducks, geese, etc.), the meat without freezing treatment is fresh livestock and poultry meat; Meat frozen at -18 or less is frozen livestock and poultry meat. The main problem causing unsafe livestock meat and by-products is that the maximum residue limit of veterinary drugs exceeds the standard. Long term consumption of food with excessive veterinary drug residues will cause a variety of acute and chronic poisoning to the human body when the drug concentration accumulated in the body reaches a certain amount. Therefore, the following four items should be paid attention to when purchasing and processing edible poultry and livestock meat and by-products:

the sales place is the key to ensure that the quarantine is qualified

when purchasing poultry and livestock meat and by-products, supermarkets or farmers' markets with complete licenses and refrigeration equipment such as refrigerators and freezers should be selected as far as possible. If the sales price is significantly lower than the ordinary market price, please buy carefully to avoid being cheated. For imported meat, special attention should be paid during the epidemic. You can ask for and check the inspection and quarantine certificate of imported goods

sensory indicators fine discrimination packaging identification should pay attention to

when purchasing fresh livestock and poultry meat, you should carefully observe whether its sensory indicators are normal. At first glance, fresh meat is shiny, and its color is not dark or black. Generally, the speed regulation range is narrow. If there is high speed, there will be no low speed or if there is low speed, there will be no high speed. The surface is wet, the tissue is uniform, and the skin color is bright; Second, fresh meat has no peculiar smell; Three touch, the surface of fresh meat is slightly dry or wet, but not sticky, and the depression will recover immediately after pressing

when purchasing frozen livestock and poultry meat, you should focus on checking whether the operating temperature of the frozen display cabinet is normal. If there is packaging, products with intact packaging, clear identification and within the warranty period should be selected, and products that are thawed and softened and have more frost in the packaging bag should be avoided

it is best to buy and eat immediately in cold storage.

the shelf life of different meat is also different. For example, the shelf life of livestock meat is relatively long, and the shelf life of poultry meat is relatively short. The fresh and frozen livestock and poultry meat purchased should be cooked and eaten as soon as possible. If it is necessary to store temporarily, it should be packaged with fresh-keeping bags or film and placed in the refrigerator for refrigeration. The storage time of fresh livestock and poultry meat in the refrigerator should not exceed 3 hours. Livestock and poultry meat frozen for a long time or thawed repeatedly will lead to the reduction of edible quality and nutritional value. If frozen storage is required, try to cut into small pieces, reduce storage time and eat as soon as possible

processing tools should be clean, cooking and heating should be thoroughly cooked.

when processing livestock and poultry meat, the middle plate and knife of the meat cutting case should be cleaned, and attention should be paid to the separate operation of raw and cooked meat. When cooking livestock and poultry meat, the meat is fully heated from the outside to the inside, which effectively kills the pathogenic microorganisms that may exist in the meat, and completely saves the manufacturing cost. It can be eaten only after it is ripe

consumption tips for nuts fried food

nuts fried food refers to the food processed with nuts, seeds or their kernels as the main raw materials. Nuts are high-energy food, rich in unsaturated fatty acids, protein, minerals, vitamin E, B group and other nutrients, with rich and comprehensive nutritional value. Common nuts include melon seeds, walnuts, pistachios, cashew nuts, hazelnuts, etc. → smooth steel strand, indented strand, compact strand, epoxy resin steel strand, prestressed steel strand, fish skin peanuts, amber peaches, strange flavor beans and other foods also belong to nut speculation

first, there are many kinds of fried nuts, each of which contains different nutrients. Consumers can choose to buy by changing and matching types according to their nutritional needs and tastes, so that the nutrition is more balanced

II. When purchasing nuts for stir frying, you should choose appropriate packaging specifications, pay attention to the production date and shelf life, and buy products within the shelf life. It is best to eat them in a short period after opening the packaging. Long term storage will affect the taste and lose their nutritional value. When selecting and eating nuts, we should choose the original nuts as the first choice, and try to eat less nuts fried with salt, baked with sugar, and oiled to reduce the intake of saturated fatty acids, salt, sugar, and additives

third, fried nuts are rich in fat, especially more unsaturated fatty acids, which are easy to oxidize and produce Khara flavor. It should be sealed and stored away from light, away from high temperature and fire sources. Oxidation and rancidity of unsaturated fatty acids will produce a large number of oxidative free radicals, increasing the risk of cardiovascular and cerebrovascular diseases and cancer

IV. people who are allergic to peanuts, cashew nuts and other products should pay attention to choosing according to their own constitution to prevent allergy

v. if you eat moldy and bitter nuts, spit them out immediately and rinse your mouth with clear water. The mildew of nuts will produce a large amount of aflatoxin, which has special affinity to the liver and carcinogenic effect. It mainly strongly inhibits the synthesis of RNA in liver cells, destroys the template effect of DNA, prevents and affects the synthesis and metabolism of protein, fat, mitochondria, enzymes, etc., interferes with liver function, and leads to mutation, cancer, liver cell necrosis, etc
