Napkins can be used in addition to wiping hands and mouth, what else can they do? In fact, whether it is injected meat, dyed yellowtail, waxed fruit, fake honey, fake wine, poor quality rice, this shoddy food can not be seen with the naked eye but can be quickly detected in front of a napkin.

 

Function 1. Check the injection of meat

How to distinguish the injected meat in the food market? Some housewives can solve the problem with a napkin. The way to detect water-injected meat with a napkin is very simple: cut the whole piece of meat, then pat the napkin onto the cut surface of the meat and wait for a minute or two. Then, the napkin will be lit, and observe the burning situation. If the napkin can burn quickly, then it means that the meat is not injected with water, if it burns more slowly or can not be lit, it indicates that the meat is water-injected meat.

 

Function 2. Identify dyed yellow croaker

Many consumers like to pick the bright yellow color of yellow croaker, think that the yellow croaker is fresh enough. Unbeknownst to them, some unscrupulous traders use pigments such as sunset yellow to artificially dye the process. So many people think of using a napkin to tell if the yellow croaker is dyed. Use a napkin to gently wipe the fish body, gills, and mouth area. If you find yellow dye residue on the paper towel, it is likely to be dyed yellow croaker.

 

Function 3. Identify the superior and inferior rice

Some unscrupulous people repeatedly grind the old rice and mix it with gutter oil or industrial raw material ash oil to make it transparent in color. This processed rice will be sold as new rice. This kind of rice is very harmful, after consumption will cause the human body general weakness, nausea, dizziness, headache, and other symptoms. Napkins can easily tell if the rice is adulterated. Wrap the rice in a napkin and place it on your palm, then clench your fist and squeeze it hard for a minute. When you unfold the napkin again, the napkin will leave numerous rice dent marks. If you can see with the naked eye that there is a faint yellow or colorless oil stain on some rice marks, it means that the rice is poor quality old rice that has been soaked and processed by gutter oil and so on. If you can't see it with the naked eye, you can place the napkin under ultraviolet light to observe. Since the oil stains will fluoresce under the light, it is easy to tell if the rice is processed and aged.
