　　【化工仪器网政策标准】番茄是一种常见的农产品，价廉物美，其酸酸甜甜的味道更是令许多人都十分喜爱他。并且随着食品深加工行业的不断发展，番茄的衍生产品种类也不断增加，如番茄酱、番茄丁、番茄粉、番茄汁、番茄沙司。

　　就番茄制品来说，营养品质和色泽作为其主要品质和感官指标，均与番茄制品中类胡萝卜素的含量有重要关系。番茄制品中的类胡萝卜素主要为番茄红素、叶黄素、胡萝卜素，其中番茄红素还是人体血浆中含量高的类胡萝卜素。因此无论是保障番茄制品品质，还是保障番茄制品的营养性，对番茄制品中的类胡萝卜素进行准确定量都十分重要。

　　但目前我国检测类胡萝卜素的方法主要为高效液相色谱法，存在检测时间过长的问题。为减少检测时间，保障色谱分离度，提升监测效率，国家标准化管理委员会下达了《番茄制品中番茄红素、叶黄素、胡萝卜素含量的测定超高效液相色谱法》制定工作，上海市质量监督检验技术研究院等单位承担了该项工作。

　　在编制过程中，研究组遵循“先进性、实用性、统一性、规范性”的原则，注重标准的可操作性，完成了检测方法的研究工作，形成了方法草案和编制说明。目前，该标准正在面向社会公开征集意见，相关人士可通过全国标准信息公共服务平台提交建议或意见。

　　该标准规定了番茄制品中番茄红素、叶黄素、胡萝卜素的测定方法，适用于番茄粉、番茄酱和番茄饮料等番茄制品中番茄红素、叶黄素、α-胡萝卜素和β-胡萝卜素的测定。

　　标准规定，本方法的检出限：当取样量为5 g、定容体积为2 mL时，叶黄素的检出限为1 μg/100g，番茄红素、α-胡萝卜素和β-胡萝卜素的检出限均为0.5 μg/100g。本方法的定量限：当取样量为5 g、定容体积为2 mL时，叶黄素的定量限为3 μg/100g，番茄红素、α-胡萝卜素和β-胡萝卜素的定量限均为2 μg/100g

　　根据文件显示，该方法需要用到超高效液相色谱仪、紫外可见光分光光度计、分析天平、组织捣碎机、涡旋振荡器、减压浓缩装置、固相萃取装置、离心机等仪器。

　　在编制中该方法的主要参数、公式、性能要求等主要依据 GB/T 1.1-2020《标准化工作导则第 1 部分：标准化文件的结构和起草规则》和GB/T 20001.4-2015《标准编写规则第 4 部分：试验方法标准》的要求进行编写，并且按照GB/T 27417-2017《合格评定化学分析方法确认和验证指南》对方法学进行了考察。

　　该标准制定的符合我国国情，方法满足食品检验的要求，准确可靠，且具有普遍适用性，易于推广。
