What is it about?
This study explores how hyperspectral imaging and artificial intelligence can predict important quality indicators in black tea during storage. By analyzing how tea interacts with visible and near-infrared light, we developed machine learning models capable of estimating pH and water activity without destructive testing. The results demonstrate the potential of this technology for faster, more efficient, and automated tea quality monitoring.

Why is it important?
Maintaining black tea quality during storage is essential for consumer satisfaction and product consistency. Conventional laboratory analyses can be time-consuming and require specialized equipment. Our research demonstrates that hyperspectral imaging combined with artificial intelligence can accurately predict key quality indicators, offering a promising non-destructive approach to food quality control and supporting the development of smarter monitoring systems.
Perspectives
These findings open opportunities for developing compact, affordable spectral sensors for real-time tea quality monitoring. Future research should focus on validating the models across different tea varieties, storage environments, and industrial conditions. Integrating selected spectral bands with portable devices and artificial intelligence could enable automated quality assessment, reduce laboratory testing requirements, and support more sustainable food processing and storage practices.
