    • The present invention relates to a method for the analysis of fat-soluble components, in particular dyes, from biological materials, in particular lipid rich foodstuffs, having an enrichment of the components and subsequent analysis. The method comprises a combination of extraction and separation steps and a subsequent analysis step. The invention further relates to an analytical kit and analytical equipment for carrying out the method. The method according to the invention is composed of a plurality of steps. The critical steps which are essential and characterize the invention are: 1.Pre-treatment of the sample to remove lipids. 2.Extracting the dyes into an extraction mixture by a specific solvent or solvent mixture. 3.Destruction of the oxidative sensible ingredients such as carotenoids prior to the final detection and quantification by eye or by optical enhancement.
    • 本发明涉及从生物材料特别是富含脂肪的食品中分析脂溶性成分,特别是染料的方法,其具有富集组分和随后的分析。 该方法包括提取和分离步骤的组合以及随后的分析步骤。 本发明还涉及用于实施该方法的分析套件和分析设备。 根据本发明的方法由多个步骤组成。 本发明所必需的和特征的关键步骤是:1.预处理样品以除去脂质。 2.通过特定溶剂或溶剂混合物将染料萃取到萃取混合物中。 3.在最终检测和眼睛定量之前,通过光学增强来破坏氧化敏感成分如类胡萝卜素。
