Pork, is a very common ingredient, when we buy pork, the boss who sells pork, why often take a rag to wipe on pork, many people may not be very clear, in fact, there is a reason, after reading it is really knowledge.
First of all, the first reason, generally sold every day, is killed in the slaughterhouse in the early morning, and when the traders pull it to the market to sell, it also takes a few hours, the pork sold by the traders every day, but also to ensure freshness, we buy fresh pork, go home and stir-fry it to eat, the taste will be better.
Generally, freshly killed pork, although it looks relatively clean after treatment, but it is inevitable that there will be blood seeping out of pork, so the butcher will take a rag to wipe the oozing blood, so that after wiping clean, not only can the appearance be improved, but the quality of the meat will be more natural, thus enhancing our desire to buy.
The second reason, if some illegal merchants, in the sale of water-injected meat, generally water-injected pork, after a period of time, the moisture in the pork, will seep out, so the merchant will also use a rag to wipe, wipe the oozing moisture, to avoid being discovered by customers, but now selling water-injected pork, generally rare, however, we must also beware of water-injected pork.
Usually, when we buy pork, we can use our hands to press the surface of the pork to identify whether the pork has been injected with water, generally normal fresh pork, we press down, the pork will be elastic, there will be a rebound situation, if we press down, the pork is not elastic, then it means that the pork is not very fresh.
If we press the surface of pork, press this position, oozing a lot of blood water, the concentration of blood water is very thin, just like clear water, which means that it is water-injected pork, if it is water-injected pork, the surface will look relatively wet, and the surface is accompanied by obvious blood water, generally we see this pork, it is best to avoid buying.
The third reason, usually traders after cutting pork, will also use a rag to wipe their hands, or used to wipe the board, because when cutting pork, it is easy to leave some mucus, or blood, wipe with a rag, you can clean off the residue on the surface, if it is in a cash transaction, wipe your hands clean, some dirty things are not easy to attach to the cash.
Usually, when we buy pork, sometimes we will also see some blackened pork, if it is a whole piece of blackened pork, then it is best not to buy, pork blackened because it has been placed for too long, not sold in time, thus affecting the quality of pork, that is to say, blackened pork, is spoiled pork.
However, if we see that part of the pork is blackened, generally this small part of the blackened pork, is before slaughter, with a wooden stick to knock the pig unconscious, the bruise caused by the injury, blackening due to bruising, will not affect the freshness of pork, so usually, we must also know how to distinguish this.
When buying pork, if it is fresh pork, the color will look light red, and there will be gloss, if it is not fresh pork, the color will look darker, generally dark red, and the meat quality looks without gloss, so usually, we have to pick fresh pork to buy.
When we buy pork, we must not only select fresh pork, but also learn to distinguish water-injected pork, if we buy water-injected pork, it has always been kept in the dark, so that long-term eating water-injected pork is also easy to affect health.
