Research and analysis on the quality status of Shaoyang special food pig blood balls

为全面了解邵阳特色食品猪血丸子产品质量现状,采用国家标准方法对邵阳地区20家不同食品生产企业生产的猪血丸子的水分、蛋白质、食盐、脂肪、酸价、过氧化值、重金属污染物、苯并[a]芘以及微生物等质量和安全指标进行重点检测研究及分析。结果表明,猪血丸子水分、食盐、脂肪、酸价、过氧化值、总砷、铅、苯并[a]芘等测定值分别为在31.9%~63.3%、1.6%~4.6%、8.5%~44.1%、1.03~7.06 mg/g、0.040~0.68 g/100g、0.005~0.054μg/kg、0.039~0.34μg/kg、ND~0.018μg/kg;对20批次猪血丸子的大肠菌群、金黄色葡萄球菌、沙门氏菌、单核增生李斯特氏菌进行检测,除个别大肠菌群有污染之外,致病菌均为未检出。猪血丸子总体产品质量可靠,个别产品存在水分、食盐、脂肪含量过高、蛋白质含量过低、酸价和过氧化值偏高、大肠菌群污染等质量问题,产品检测数据可为制定猪血丸子产品相关地方标准或地方性规定提供数据支持。

objective:to understand the quality status of pig blood balls,a special food in Shaoyang,and to provide data support for the formulation of relevant local standards or regulations.Methods:the water,protein,salt,fat,acid value,peroxide value,heavy metal pollutants,benzo[a]pyrene and microorganisms of quality and safety indicators about pig blood balls produced by 20 different food manufacturers in Shaoyang were detected and analyzed by the national standard method.Results:the determination values of water,salt,fat,acid value,peroxide value,total arsenic,lead and phenylalanine[a]pyrene were 31.9%~63.3%,1.6%~4.6%,8.5%~44.1%,respectively,1.03 mg/g-7.06 mg/g,0.040.0.68 g/100g,0.005-0.054 ug/kg,0.039-0.34 ug/kg,N.D-0.018μg kg,the coliform,Staphylococcus aureus,salmonella and Liszt monocytogenes of 20 batches of pig blood pellets were detected,no pathogenic bacteria were detected.Conclusion:the present quality of Zhuxue pill is reliable,there are some quality problems in some products,such as water,salt,high fat content,low protein content,high acid value and peroxide value,coliform contamination,etc.,the product testing data can provide data support for the formulation of local standards or local regulations related to pig blood pill products.
