Impact of storage temperature on green tea quality: an assessment based on compositional changes

After 300 days of storage, the dry storage zone (4 °C) not only showed excellent preservation performance but also offered lower storage costs, making it the optimal condition for the long-term storage of green tea. This study contributes to establishing a comprehensive database for dry-stored green tea under refrigeration and provides a scientific basis for low-temperature, dry-zone storage strategies. © 2025 Society of Chemical Industry.
