摘要
目的了解我国生鲜肉及肉制品中磷酸盐的本底及食品添加剂磷酸盐使用的实际情况,为制定肉制品中磷酸盐的合理限量提供科学依据。方法从14个省、市、自治区中选择有代表性的屠宰厂及市场对猪肉、牛肉、鸡肉生鲜肉和肉制品采样,按照食品中磷酸盐的测定方法进行磷酸盐含量分析。结果以磷酸盐(PO43-)计,生鲜猪肉、牛肉、鸡肉中磷酸盐本底含量的全国平均值分别为5115.22mg/kg、4614.02mg/kg、4897.23mg/kg,熟肉制品中磷酸盐含量的全国平均值为5086.59mg/kg。生鲜牛肉、鸡肉中磷酸盐平均含量接近《熟肉卫生标准》中磷酸盐5g/kg的限值,生鲜猪肉、熟肉制品中磷酸盐平均含量超过该限值,由于生鲜肉中磷酸盐本底含量较高,肉制品生产企业按照《食品添加剂使用卫生标准》添加磷酸盐也会超过《熟肉卫生标准》中磷酸盐限量。结论《熟肉卫生标准》和《食品添加剂使用卫生标准》之间存在一定的问题,需要对相关标准进行修改。
Objective To study the background content of phosphate in fresh meat and meat product and using condition of phosphate as food additive, and to provide scientific basis for reasonable limit content of phosphate in meat product. Method The fresh meat and meat product were sampled from representative slaughterhouses and markets in 14 provinces, and phosphate content were determined according to GB/T 5009.87--2003 ＂the analysis methods of phosphate in food＂. Results The average phosphate contents in fresh pork, beef and chicken were 5 115.22 mg/kg, 4 614.02 mg/kg and 4 897.23 mg/kg, respectively, and the average phosphate content of cooked meat products was 5 086.59 mg/kg. The average contents of phosphate in fresh beef and chicken were close to 5 g/kg of the limit content of ＂hygienic standard for cooked meat product＂. The average contents of phosphate in fresh pork and cooked meat products exceeded the limit content. Although the enterprises of meat products added phosphate according to ＂hygienic standard for use of food additives＂, the phosphate content still will exceed the limit content of ＂hygienic standard for cooked meat product＂ because the background content of phosphate in fresh meat was higher. Conclusion Such two standards were inconsistent and should be revised.
