Go to the supermarket to buy packaged lettuce salad, if the air inside is swelling, it will be bad. Similarly, if some signs appear in packaged raw meat, it means it is no longer fresh, and it is best not to put it in the shopping cart.
What is the appearance of sealed meat not fresh? There is a lot of liquid in the sealed bag, pink or red juice, which means it is stored incorrectly and may have been stored for a long time.
However, red liquid is not blood. The meat sold in the store and the blood has been dried up at the slaughterhouse. In the beef, the moisture content is 75%. When wrapped, it will expel the moisture mixed with myoglobin (also refines myoglobin), which is the red liquid.
Since this liquid is a natural thing, why is it not good? The function of sarcoin is to preserve liquids. If the meat is left for a long time or is not properly treated, the sarcoin will decompose, lose the function of preserving moisture, reduce the meat quality, and add water. This liquid, like raw meat, may become a parasite for bacteria. This "raw meat water" must be handled carefully and do not let it get stuck in other things in the shopping cart. Before putting it in the shopping cart, please figure it out carefully. If this bag of raw meat is not cold, just forget it, don’t buy it.
To determine the quality of meat, except for no water flowing out, another important indicator is that the texture of fat must be clear. If you touch the hard block, it is soft bone. Bright red or purple are also indicators of high-quality meat. If the beef is brown or brown, it may be a sign of oxidation or even rot.
Another small trick to buy freshly packaged meat is to get the meat before you get it, and finally put it in the shopping cart. Raw meat is prone to rot, so don't put it in the shopping cart at the beginning, then push the cart to visit the entire supermarket, and then go and register after buying enough shopping on the same day. By the same token, when buying raw meat in hot weather or during seasons, it is best to prepare small boxes and cold bags in the car to keep the meat fresh between the supermarket and the refrigerator at home to prevent bacteria from growing. You will be more confident if you buy good meat, go to the local farm market, or slaughter shop that sells all cattle and all sheep.
