水发产品卫生学调查

目的]了解水发产品的生产模式、加工工艺、水发剂使用的情况以及本市市售水发产品中甲醛与过氧化氢残留情况。方法]用现场调查与抽样检验结合的方法,对市售水产品进行检测,对水发产品的生产模式、加工工艺、水发剂使用等情况进行调查。结果]水发产品生产整体尚处于较低水平,调查中未发现有在水发过程中使用甲醛的情况,而使用过氧化氢的情况较为普遍,抽检的212件水发产品甲醛不合格率为9.0%,抽检的97件水发样品过氧化氢检出率为2.1%。结论]产品中检出甲醛不合格率较高、过氧化氢检出率低;水发产品的原料中可能有甲醛本底的存在,而过氧化氢在产品中的残留相当不稳定。

Survey on the hygienic situation of waterishlogged food products

Objective] To know the manufacture pattern,processing procedure of the waterishlogged food products,and the chemicals used in manufacture.To discover the residua of formaldehyde and hydrogenperoxide in waterishlogged food products in market. Methods] Scene investigation combined with sample proof-test. Results] The manufacture of waterishlogged food products remained in an original level.People did not use formaldehyde in processing,but use of hydrogenperoxide was common.The disqualification rate of formaldehyde was 9.0%,the disqualification rate of hydroperoxide was 2.1%. Conclusion] The disqualification rate of formaldehyde was relatively high,while that of hydrogenperoxide was relatively low.The food stuff before waterishlogging may contain some formaldehyde while the hydrogenperoxide in the products is unstable.
