Study on the Determination Methods of Five Additives in Meat Products

Meat and meat products play an important role on our dining table.As the world's larger producer and consumer of meat and meat products,China has various and abundant meat products.The processing technology of meat products is different,and the use degree and national standards of additives are also different.Meat products are easy to spoil,leading that the abuse and misuse of additives happen occasionally.Currently,traditional methods for detecting additives in meat products have numerous deficiencies,including single detection type,low accuracy and longer period.Meat and meat products are rich in fat and protein,and the detection results are easily affected by fat and protein in the detection process.Based on this,the treatment of meat products in the early stage of the detection of additives are carefully studied and optimized in this experiment,and the optimal treatment plan is obtained as follows:the ultrasonic time is 15 min,the ratio of solvent ethanol,ammonia water and water is 7∶2∶1 and the protein precipitating agent is lead acetate.
