Optimization of kombucha production using organic green tea (Camellia sinensis) and specialty coffee (Coffea arabica): Production optimization, physicochemical composition, microbial viability, and sensory evaluation
This study utilized a Central Composite Rotatable Design to optimize kombucha production from organic green tea and specialty coffee, revealing that while high tea concentration boosts phenolic content and acidity, formulations with higher residual sugar and balanced acidity achieved the best sensory acceptance and market potential.
