原料肉中磷酸盐本底含量状况调查与分析

Investigation of background concentration of phosphate in raw meat

运用比色法,先后对5类1353个生肉样品、5类121个副产品样品,共计1474个原料肉样品进行了磷酸盐本底含量的测定。结果表明,原料肉中磷酸盐本底含量范围为1.49～16.5g/kg,多数处于低端水平;不同种类的生肉中磷酸盐含量存在显著差异(P<0.05),其中生猪肉中磷酸盐含量最高,其次为鸭肉,生羊肉中磷酸盐含量最低;不同种类的副产物中磷酸盐含量存在显著差异(P<0.05),其中生猪肝中磷酸盐含量最高,其次为生牛肝,生猪肠、肺中磷酸盐含量最低。

The background concentrations of phosphate in 1474 raw meat samples,including 1353 samples of 5 species of raw meat,121 samples of 5 species of byproducts,were determined by colorimetry.The results showed that the scope of concentrations of phosphate in raw meat was 1.49～16.5g/kg,most of the samples had low concentration.While phosphate content in pork seem to be significantly higher than other raw meat species（P0.05）,followed by raw duck meat,however,the content in mutton was the lowest.Phosphate content in pork liver also seem to be significantly higher than other byproducts（P0.05）,followed by bovine liver.The content in pork chitterlings and lung was the lowest.
