由于食品立法要求控制方法,因此必须提供可靠的分析方法,以使法规的执行成为可能。通过使用符合某些性能标准(在实验室间研究中得到证明)的方法,可以提高分析数据的可靠性,建议采用分析质量保证程序,包括使用(经认证的)参考物质,特别是在需要高度比较和准确度的情况下。良好的分析方法和AQA是充分执行食品法的先决条件(粮农组织,2004年)。有关验证的更多信息,请参阅本节“赭曲霉毒素A官方分析方法概述”中的其他支持文件。
As food legislation calls for methods of control, reliable analytical methods have to be available to make the enforcement of regulations possible. The reliability of analysis data can be improved through the use of methods that fulfil certain performance criteria (demonstrated in interlaboratory studies) and the application of analytical quality assurance (AQA) procedures is recommended, including the use of (certified) reference materials, especially when high degree of comparison and accuracy are required. Good analytical methodology and AQA are prerequisites for adequate food law enforcement (FAO, 2004).
