Why can't litchi eat more?

Although litchi is good, it is easy to get angry. If you eat too much, your mouth will rot or your nose will bleed. There is a saying in Guangdong that "one litchi has three fires". Don't think it's exaggerated. Some people do have adverse reactions when they eat too much. If you eat a lot of fresh litchi for several days in a row, it will lead to excessive internal heat and disorder of glucose metabolism in your body. Many people will have dizziness, palpitation, pallor, hunger, cold sweat and other symptoms. In severe cases, convulsions, irregular breathing, weak pulse and even sudden coma may occur. This is acute litchi poisoning, also known as litchi disease.

Because litchi is warm and dry, it is best for people with yin deficiency and fire to eat less; If you are suffering from acne, sores, colds or acute inflammation, you are not suitable to eat litchi, otherwise it will aggravate your condition. For children, litchi should not be eaten more. However, people who are weak and have a cold stomach can eat more.

If eating litchi gets angry, there is no need to panic. The popular folk solution is to drink a proper amount of light salt water or honey water, or to have a cup of "fire-reducing" tea (9 grams of Scrophularia, 9 grams of Ophiopogon japonicus, 3 corduroy flowers, 3 bowls of water for one bowl), or to eat cold watermelon. If you eat litchi disease, you should lie flat immediately, and then drink a cup of concentrated sugar water to recover, but serious cases should be sent to hospital in time for treatment.

Beware of adulteration and renovation of "water-injected meat"

"Water-injected meat" is artificially injected into raw meat, mainly in pork and beef, for the purpose of gaining weight and making profits. Water can be injected into animals at a certain time before slaughter or into meat after slaughter. The water injection amount can reach 15% ~ 20% of the net weight. Water-injected meat is generally lighter than normal meat. The surface is not sticky, and there is quite light red blood flowing out after it is placed. Meat water injection violates food safety laws and regulations, damages consumers' rights and interests, and reduces the taste quality of meat. At the same time, the sanitary problems of injected water seriously affect human health.

But you know what? The adulteration technology of "water injection meat" has improved! According to Chongqing Business Daily, the adulteration method of "water-injected meat" has been quietly renovated, and some illegal slaughterhouses and butchers are trying their best to increase the weight of meat. In fact, carrageenan, a chemical raw material, is diluted with water and injected into the animal to be slaughtered, which is not as easy to be found as "water-injected meat".

The media commented that this adulteration was original in Chongqing. You can even apply for a patent Because compared with the "water-injected meat" we knew before, the method of injecting carrageenan is more secret. According to unscrupulous traders, in the past few years, whether it was pork and beef business or chicken, duck and rabbit business, the method of adulteration was water injection. However, due to poor water retention, law enforcement officers and even ordinary citizens take measures such as cutting with a knife and squeezing with toilet paper. You can let the "water-injected meat" show its true colors. Carrageenan injection is very effective now, and it is not easy to be found.

According to law enforcement agencies, the operation method of carrageenan injection method is: mixing carrageenan and water according to the ratio of 3: 1000, heating, and injecting "glue" into the animal to be slaughtered after carrageenan is dissolved in water. After such animals are slaughtered, not only is the "moisture" not easy to overflow, but the meat looks more tender.

Carrageenan has a thickening effect, and a catty of meat will not appear "glue" when injected in pairs. Carrageenan, scientific name carrageenan, carrageenan, is a food chemical raw material. Its main colloidal substance is extracted from red algae. Carrageenan products are generally colored or yellowish powder, odorless and tasteless. Because of its many physical and chemical properties and excellent water solubility, it can form high-viscosity solutions and gels, so it is often used in food industry, daily chemical industry, biochemistry, medicine and other fields.

Obviously, this kind of meat is not good for human health. We must pay attention. Experts remind consumers to master the identification method of "water-injected meat" in a targeted manner.
