Mixing strawberries ground under liquid nitrogen with polyvinylpyrrolidone alone or combined with Amberlite XAD-4 in pH 4.5 buffer yielded stable polyphenoloxidase (PPO) extracts. Temperature stability of the enzyme varied with substrate and followed

Stable and highly active polyphenoloxidase (PPO) extracts were obtained using polyvinylpyrrolidone, Amberlite XAD-4, Triton X-100, and protease inhibitor in pH 5.25 buffer. Citrate and phosphate prevented binding of PPO to pectin. Phenyl sepharose ch

Two purified fractions of strawberry polyphenoloxidase (PPO) were used in model systems containing D-catechin alone or in combination with either pelargonin or cyanin. Km values using D-catechin were 0.5 mM and 0.41 mM and Vmax 82,700 and 18,800 nmol

Polyphenol oxidase (PPO) was extensively purified to homogeneity from d'Anjou pear (Pyrus communis L.) by extraction in the presence of the phenolic binder AG 2-X8 andTriton X-100. Chlorophyll pigment was removed by chromatography resulting in a clea
