Applications of Bromelain from Pineapple Waste Towards Acne

Bromelain is a proteolytic mixture obtained from pineapple ( (L. Merr)). It has diversified clinical properties and is used in alleviation of cancer, inflammation and oxidative stress. The current study focuses on extraction of bromelain from different parts of pineapple such as core, crown, fruit, peel and stem. The extracted enzyme was precipitated using ammonium sulphate at 40% saturation followed by dialysis. The fold of purification obtained for peel, crown, core, fruit and stem were found to be 1.948, 1.536, 1,027, 1.989, and 1.232 respectively. Bromelain activity was estimated using Azocasein assay, the highest activity was seen in peel at 3.417 U/μg. Antimicrobial activity and MIC of the bromelain purified and crude fractions was studied against the test organisms. Peel crude and purified extract exhibited highest inhibitory effect towards followed by The antioxidant activity was evaluated using DPPH antioxidant assay. IC50 values peel, fruit, stem and crown are found to be 13.158 μg/ml, 24.13 μg/ml and 23.33 μg/ml and 113.79 μg/ml respectively. The purified bromelain from peel, stem and crown was used to create a facewash formulation towards pathogens frequently associated with skin infections. Common skin pathogens like and were found highly sensitive to its action. The aim of this study was to evaluate the potential of bromelain isolated from waste parts of pineapple in alleviation of acne due to its diverse antimicrobial properties.
