    Acrylamide is a kind of white crystal chemical, which is the raw material for the production of polyacrylamide. Polyacrylamide is mainly used for water purification treatment, the processing of pulp and the inner coating of the pipeline, etc.. Starch food in the high temperature (>120 C) under the easy to produce acrylamide cooking. Study shows that the human body can be exposed to acrylamide through the digestive tract, respiratory tract, skin and mucous membranes, and drinking water is one of the important ways. That occupation population of acrylamide exposure and accidental exposure to acrylamide population survey, acrylamide is neurotoxic, but the WHO said that due to the statistics to which an acrylamide concentration can be carcinogenic, so it is difficult to set safety standards. In April 2002, the Swedish National Food Administration and Stockholm University researchers first reported in some starchy foods such as fried and grilled, fried French fries, potato chips and other detection of acrylamide, and the content is more than 500 times the limit allowed * * * in drinking water.

     

    Tengzhou Xiangying Analysis Technology Co. Ltd. by GC7990 gas chromatography, water quality determination of residual acrylamide, with satisfactory results.

    丙烯酰胺是一种白色晶体化学物质,是生产聚丙烯酰胺的原料。聚丙烯酰胺主要用于水的净化处理、纸浆的加工及管道的内涂层等。淀粉类食品在高温(>120℃)烹调下容易产生丙烯酰胺。 研究表明,人体可通过消化道、呼吸道、皮肤黏膜等多种途径接触丙烯酰胺,饮水是其中的一条重要接触途径。对接触丙烯酰胺的职业人群和偶然暴露于丙烯酰胺人群的调查表明,丙烯酰胺具有神经毒性作用,但世界卫生组织表示,由于难以统计丙烯酰胺要到哪一个浓度才会致癌,所以难以订立安全标准。2002年4月瑞典国家食品管理局和斯德哥尔摩大学研究人员率先报道,在一些油炸和烧烤的淀粉类食品,如炸薯条、炸土豆片等中检出丙烯酰胺,而且含量超过饮水中允许***大限量的500多倍。

    滕州市翔鹰分析技术有限公司采用GC7990气相色谱仪,测定水质 丙烯酰胺残留,结果满意。
