Most people use salt to clean the pork belly, but the effect is not particularly good. If you use some vinegar in the cleaning process, the effect will be better. Because according to the function of salt vinegar, it can remove some dirty smell in the stomach and mucus in the skin, which is also the reason why vinegar changes the color of collagen and coagulates; Salt has the function of high osmotic concentration. Through the action of salt and vinegar, collagen is removed from the stomach wall, thus achieving the effect of eliminating waste and odor. After cleaning, put your stomach in cold water and scrape off the cocoon tips with a knife. Never use alkali when washing your stomach. Because alkali is very corrosive, the mucus on the belly surface will fall off under the action of clothes, which will also destroy the protein on the belly wall and reduce the nutritional composition of the belly. To remove the foul smell in the pig's belly, first wipe the pig's belly with wheat flour, put it in clear water to wash away the dirty mucus, then put it in a boiling water pot to cook until the white navel is taken off, then put it in cold water, and scrape off the dirt on the white navel with a knife. After washing, cut from the belly head (the thick part of the meat) to remove the oil stains in the inner cavity, and then rub the stomach with a small amount of vinegar and edible salt to remove shame and odor.

When the temperature rises to 50 degrees, the white and light yellow films adhered around the stomach and esophagus of pigs will fade. At this time, gently surround it with a wooden shovel. When the yellow film can be removed, fish out the pig's stomach in time. Note that if the water temperature is too high or the temperature rises too fast, it is difficult to remove this film, so we must grasp the temperature and timing of the water.

If the water temperature is moderate, it is easy to tear off the yellow film by hand after fishing out. After tearing off the yellow film, continue to remove the residual mucus on the surface of the pig's belly with a knife. Rinse the neatly closed residue with clean water.
