Vitamin A, a fat-soluble vitamin, is essential for health and plays an important part in vision, bone growth, reproduction, regulating the immune system, cell function, and skin health. Due to the advances in technology and the expansion of its uses, LC technologies are being studied for effectiveness in detecting and quantifying vitamin A in an effort to help determine the amount of vitamin A in various types of samples. For this reason, an Expert Review Panel agreed on June 29, 2011, at the "Standards Development and International Harmonization: AOAC INTERNATIONAL Mid-Year Meeting," to approve "Determination of Vitamin A in Infant Formula and Adult Nutritionals by UPLC-UV" as AOAC Official Method 2011.07. To move from First to Final Action status, it was recommended that additional information be generated for all types of infant formulas and adult nutritional formula matrixes at varied concentration levels, as indicated in the standard method performance requirements. International units or retinol equivalents typically represent the concentration of vitamin A in food and supplements. However, for the purpose of this method, the concentration represented is presented in microg/100 g.
维生素A是一种脂溶性维生素，对健康至关重要，在视力、骨骼生长、生殖、调节免疫系统、细胞功能和皮肤健康方面发挥着重要作用。由于技术的进步及其用途的扩展，正在研究液相色谱技术在检测和定量维生素A方面的有效性，以帮助确定各类样品中的维生素A含量。因此，一个专家评审小组于2011年6月29日在“标准制定与国际协调：AOAC国际年中会议”上，批准了“超高效液相色谱-紫外检测法测定婴儿配方食品和成人营养食品中的维生素A”作为AOAC官方方法2011.07。为从初审状态转变为终审状态，建议按照标准方法性能要求，针对不同浓度水平的各类婴儿配方食品和成人营养配方食品基质生成更多信息。国际单位或视黄醇当量通常表示食品和补充剂中维生素A的浓度。然而，对于本方法而言，所表示的浓度以微克/100克为单位。
