Abstract：
Foods are analysed for their vitamin content to support the verification of regulatory compliance or to generate food composition data. Many international reference methods for the analysis of vitamins in foods originate from the 1990s. Advances in nutrition science and analytical technology and the continuing evolution of statutory regulations necessitate the need of new or supplementary regulatory standards. We have evaluated recent developments in these areas and conclude that most current international reference methods are no longer fit-for-purpose to accurately determine vitamin content in foods and food supplements. We have made recommendations to consider new and/or updated reference methods and regulatory standards for the analysis of vitamins A, D, E, K, B1, B2, B3, B5, B6, B7, B9, B12, C and carotenoids in foods and food supplements. This area of nutrients may benefit from globally harmonised definitions specifying what compounds to include or exclude for analysis, and applicable bioactivity factors.

分析食品的维生素含量，以支持对合规性的验证或生成食品成分数据。许多用于分析食品中维生素的国际参考方法起源于1990年代。营养科学和分析技术的进步以及法律法规的不断发展，需要新的或补充的监管标准。我们评估了这些领域的最新发展，并得出结论，大多数当前的国际参考方法不再适合准确确定食品和食品补充剂中的维生素含量。我们已提出建议，以考虑新的和/或更新的参考方法和监管标准来分析维生素A，D,E,K,食物和食品补充剂中的B1，B2，B3，B5，B6，B7，B9，B12，C和类胡萝卜素。这一领域的营养素可能会受益于全球统一的定义，这些定义规定了要包括或排除哪些化合物进行分析。和适用的生物活性因子。
