Conteúdo: | Peroxidade (EC 1.11.1:7) hydrogen donor oxidoreductase) is a member of a large group entitled oxidoreductases. The formation of off-flavours in canned fruit and vegetables has been associated with residual peroxidase activity following processing. Peroxidase can catalyse the oxidation of vitamina, aromatic compounds and growth regulating substances. High temperature short time (HTST) in order to destroy peroxidase activity and prevent regeneration has been shown to be not effective. The present study was to investigate peroxidase in pineapple. The peroxidase in the form of a mixture of isoenzymes, i. e., the crude soluble and ionically bound extracts were submitted to heat treatments and subsequentely analysed for their residual enzymatic activity. The solublefraction has shown to be more heat stable than the ionically bound peroxidase fraction.
