The Carotenoid Content Assay Kit is widely used in research and quality control to measure carotenoid levels in various biological samples, including plants, fruits, vegetables, and food products. It is essential for assessing nutritional value, as carotenoids are vital antioxidants and precursors to vitamin A. In agriculture, the kit helps in evaluating crop quality and optimizing breeding programs to enhance carotenoid-rich varieties. In the food industry, it ensures compliance with labeling regulations and monitors carotenoid stability during processing and storage. Additionally, it supports biomedical studies investigating the role of carotenoids in human health, such as their impact on vision, immune function, and chronic disease prevention.
