Basic introduction:

As early as 1892, Chittenden discovered the presence of an enzyme that hydrolyzes proteins in the tissues of bromeliaceae pineapples and named it bromelain. 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.
