Bromelain is a protein hydrolase, extracted from pineapple stems is a pure natural plant protease, with strong ability to break down fibrin and blood clots, at the same time, bromelain has anti-inflammatory, enhance drug absorption, prevent cardiovascular diseases, inhibit the growth of tumor cells and other effects, widely used in the pharmaceutical industry.
Bromelain is a protease extracted from the skin and stem of pineapple. The production of bromelain can solve the problem of environmental pollution and waste of resources caused by the large amount of waste discarded in the pineapple industry, and can also make high value use of pineapple products. Pineapple protease belongs to the papaya enzyme family and is classified into stem pineapple protease (EC3 - 4 - 22 - 32) and fruit bromelain (EC3 - 4 - 22 - 33) depending on the isolation and extraction site. - The molecular weights of these two enzymes are 33 kDa and 28 kDa, and their isoelectric points are 9.5 and 4.6, respectively. Bromelain has a wide range of applications in the pharmaceutical and food industries. In the pharmaceutical field, bromelain is used for the removal of necrotic tissue from ulcers and burns because of its antithrombotic, antiedema and anti-inflammatory effects. In the food industry, pineapple protease is widely used for meat tenderization, beer clarification, dry cool production and protein hydrolysis.
