深圳市2006～2007年非发酵性豆制品监测结果分析

Study on monitoring results of Non-fermented bean products in Shenzhen during 2006 to 2007

目的了解深圳市非发酵性豆制品的卫生状况,发现关键性问题并进行分析,为制定相应的标准和针对性措施提供依据。方法按照《深圳市食品污染物监测体系项目工作方案》的要求,在全市范围内采集非发酵性豆制品共139份样品,按GB/T4789-2003和GB5009-2003方法进行测定,并对此类食品2年的合格情况以及不合格项目进行统计分析。结果非发酵性豆制品2006年和2007年的合格率分别为43.75%、22.67%,合格率甚低,卫生质量下降明显,不合格项目中主要为大肠菌群、甲醛和甲醛次硫酸钠。结论非发酵性豆制品微生物污染问题依然严重,非法添加甲醛次硫酸氢钠已成为又一导致该类食品不合格的主要原因,应将甲醛次硫酸氢钠纳入到非发酵性豆制品的常规检测项目,加大监督监测力度。

Objective To understand the sanitation situation of non-fermented bean products in Shenzhen, find out and analyze the key points, and provide reliable evidence for establishing correspondent standard and suitable control measure. Methods According to Sbenzhen Foodstuff Contamination Inspection System Guidance, 139 samples of non-fermented bean products in the city had been collected and tested according to GB/T4789-2003 and GB5009-2003 standard. Results Comparing the results of 2006 with 2007, the eligible rate of non-fermented bean products declined obviously. The main unqualified item was coliform group, formaldehyde and sodium formaldehyde sulfoxylate. Conclusion The microbial contamination of non-fermented bean products is still serious. The illegal use of Sodium formaldehyde sulfoxylate has become another main reason for substandard non-fermented bean products. Sodium formaldehyde sulfoxylate should be brought to testable item in common. The test and inspection for sodium formaldehyde sulfoxylate in such food should be strengthened.
