Abstract

The present protocol described extraction of active polyphenol oxidase and peroxidase from a plant rich in phenolics and chlorophylls in the post-harvest browning syndrome of B. myrtifolia.  Initially, general optimisation using conventional enzyme extractions was performed.  However, along with membrane-bound proteins, chlorophylls and phenols were also released with Triton X (TTX).  With a view to obtaining high enzymatic activity, removal of the released chlorophylls and phenols by formation of TTX-114 micelles in the detergent rich phase after high-temperature induced phase separation was tested.
