The natural (benchmark) moisture content of various meats can be measured (calibrated) in advance by the national standard method. For example, the benchmark water content of several kinds of meat in Beijing, which is calibrated by Beijing Industrial and Commercial Bureau, is 62. 1% for pork, 63.3% for beef, 63. 1% for mutton and 60.9% for chicken. According to the national water limit standard for livestock and poultry meat, the water content of pork, beef and chicken is more than 77%, and the water content of mutton is more than 78%, which can be judged as water-injected meat or water content exceeding the standard.

SFY-30 meat quick moisture analyzer produced by Shenzhen Guanya (this model is livestock and poultry meat moisture detection: government procurement supporting products) can quickly and accurately detect the moisture content of water-injected meat, so that the water-injected meat is exposed. At present, the instrument is widely used in industrial and commercial bureaus, food supervision and safety administration, central meat cold storage, meat product enterprise groups and so on all over the country.
