A novel tannase from Klebsiella pneumoniae KP715242 reduces haze and improves the quality of fruit juice and beverages through detannification

Frontiers in Sustainable Food Systems, 2023
The presence of high tannin content in fruit juices and other beverages generates bitterness and haze formation with a concomitant deterioration of their quality. This problem could be circumvented by treating these food products with the enzyme tannase (
