This meat is for money also do not eat because it can destroy the stomach, causing cancer

Many families have a habit of putting chicken, pork, fish and other meat products in the corner of the refrigerator and are often forgotten, after a few months to half a year to discover, so can this meat be eaten? ?

The term "zombie meat" is derived from media reports and is an exaggerated description of frozen meat marketed after being frozen for years . They are mainly smuggled products, quality and safety are not guaranteed. In fact, many family refrigerators also store some meat that has been frozen for a long time.

Meat expert Li Hung Dan, an associate professor at the Food Science and Nutrition Engineering Institute of China Agricultural University, said different types of meat have different cold storage times. Normally, meat left in the fridge for more than half a year has been considered too long .

Duration of use of the meat

• After buying frozen meat, it is best to eat it within 1 month, eat it as soon as possible.
• Fresh meat (meat after slaughtering temperature of meat within 24 hours reduced from 0 ℃ -4 ℃ and sold in the market) is best to eat immediately after buying, if not finished eating can be sure in the refrigerator at a temperature of 0 ℃ -4 ℃, eat for 3 days.
• Hot meat (meat after surgery is not chilled or frozen, but it is brought directly to the market for sale), after buying this meat, it should be used up. At room temperature, meat is susceptible to microbial contamination and they grow rapidly, relatively poor safety, especially in the summer, can be bought in the morning but at night there is an unpleasant odor.

How does eating frozen meat for too long destroy health?

Refrigerators are not a "safe" place to store meat. Frozen meat reserves for too long even when it has not expired, feeling hard to eat, loss of freshness, greatly affecting safety and nutrition.

1. Increase aging

The low temperature of the freezer can stop the growth of bacteria, but it absolutely cannot prevent the oxidation of fats and proteins, and it absolutely cannot prevent the deterioration of meat quality. Due to the oxidation reaction, the color of lean, leaky lean meat will turn from red to brown and the fat will gradually turn yellow. Not only does the flavor become inferior, it also creates fat oxidation products that accelerate the aging rate of the human body.

2. Increased risk of cancer

Expired frozen meat contains many bacteria and even viral parasites, which are harmful to the body. Long-term consumption of expired frozen pork may impair human immunity and increase the risk of cancer.

3. Losing large amounts of vitamins

The long time to freeze not only makes the flavor worse, but if the protein is oxidized, it will break down essential amino acids. The longer it takes to freeze, the greater the loss of vitamins, especially in B vitamins.

These 6 types of pork should be removed

1. Do not eat sick pork

Dead pork often carries pathogenic microorganisms, which can even contain unknown toxins, conventional cooking methods that are difficult to kill bacteria. Therefore, it is recommended that people buy meat at standard supermarkets and farmers' markets, do not buy meat too cheap compared to the market, because it is possible to buy dead pork.

2. Do not eat overcooked meat

Therefore, when you buy meat you need to observe the surface of the market, if you find that the seeds are white and the size of rice is not purchased.

4. Avoid eating fried salted pork at high temperatures

Salted pork contains nitrates. After frying at high temperatures it will create carcinogenic nitrosopyrrolidine. Therefore, when eating salted fish, bacon, sausages, ham and other foods, avoid frying.

5. Do not immerse meat in hot water

Washing pork with hot water will affect the taste of pork. You can first wipe the surface of the pork with a clean cloth and then rinse it off with cold water.

6. Do not thaw frozen meat

When defrosting meat, it is best to remove it from the freezer first and place it in the freezer overnight, the meat will be thawed naturally, less loss of flavor after defrosting. If the meat is thawed again in the refrigerator will increase the growth of bacteria in the meat, eating will be dangerous for health.
