                                According to extensive food science research, the enzyme bromelain is highly sensitive to heat, and pasteurization, a standard food preservation technique, uses temperatures high enough to cause its denaturation. This process renders the enzyme inactive, meaning virtually no active bromelain in pasteurized pineapple juice remains available.
