Aluminum (Al) has been well known as an environmental factor that may affect several enzymes and other biomolecules related to Alzheimer's disease. The increasing use of Al in the preparation and storage of food currently represents the main form of Al exposure for the general public. The present study was aimed to develop a household procedure for the rapid test determination of Al in edible jellyfish. The method was developed based on the reaction of Chrome Azurol S with Al in acidic medium, forming a colored compound on the surface of filter paper. Experimental design methodologies were used to optimize the measurement conditions. The proposed method was applied successfully to the analysis of Al in edible jellyfish products in clinical laboratory and household settings.
铝（Al）作为一种环境因素已广为人知，它可能会影响与阿尔茨海默病相关的多种酶和其他生物分子。目前，铝在食品制备和储存中的使用增加，这是普通公众铝暴露的主要形式。本研究旨在开发一种用于快速检测食用海蜇中铝含量的家庭操作方法。该方法基于铬天青S在酸性介质中与铝的反应，在滤纸表面形成有色化合物。采用实验设计方法优化测量条件。所提出的方法已成功应用于临床实验室和家庭环境中食用海蜇产品中铝的分析。
