Bromelain is a natural proteolytic enzyme extracted from the stems and fruits of pineapples. Its main component is cysteine protease, and its active site contains a sulfhydryl group, enabling it to hydrolyze a variety of proteins.
Due to its stable enzyme activity and strong protein hydrolysis capacity, bromelain is widely used in food processing, health products, cosmetics and the pharmaceutical industry. Featuring high safety, good solubility and mild action, it is a popular natural active ingredient in the global market.
