中文摘要:

      为帮助人们加深对燕窝中亚硝酸盐风险的理解和认识, 促进燕窝行业的健康发展, 采用国标检测方法(GB 5009. 33-2010)对燕窝中亚硝酸盐含量分布及燕窝中亚硝酸盐成因进行探讨, 从危害识别、危害描述、暴露评估和风险描述等方面对燕窝中亚硝酸盐的风险进行全面的综述分析。根据含量分布情况及亚硝酸盐自身毒性情况, 提出了风险管理建议, 建议将干官燕中亚硝酸限量设为30 mg/kg, 燕窝即食产品限量设为5 mg/kg, 对人体是安全的。

英文摘要:

      To enhance the understanding on the risk of nitrite in edible birdnest (EBN) and consequently to promote the well-being development of EBN industry, the risk assessment of nitrite in EBN was evaluated. The distribution and contributing factors of nitrite content in EBN were investigated by the method of GB 5009.33-2010. Nitrite is formed naturally by the nitrogen cycle during the process of nitrogen fixation and two main nitrite salt forms occur, namely sodium and potassium nitrite. Nitrate and nitrite toxicity are exactly the same syndrome and these terms can be used interchangeably. According to the nitrite contents in edible birdnest (EBN) and products originated from EBN, acceptable daily intake (ADI) suggested by FAO/WHO and toxicology data of nitrite, the tolerance limits of nitrite in EBN and products originated from EBN were suggested with 30 mg/kg and 5 mg/kg, respectively, which might be safe for human being.
