The research on the extraction and effect of bromelain began after the Second World War. The use of bromelain dates back to 1957, when Dr. Hynek first introduced bromelain into medical research. Bromelain was extracted from pineapple stem and purified by pure physical method.Enzymology Committee No.: 3.4.22.32Definition of enzyme activity unit: it refers to the hydrolysis of casein to produce 1 μ G The amount of enzyme required for tyrosine.
