Optimizing brewing conditions for low-temperature green tea infusions: Insights into functional and nutritional properties.

In response to growing demand for functional, minimally processed foods and rising energy costs, various brewing conditions for low-temperature green tea production were explored as an alternative to high-temperature processing.
