Polyphenol oxidase from yacon roots (Smallanthus sonchifolius)
(Amer Chemical Soc, 2007-03-21)
Polyphenol oxidase (E.C. 1.14.18.1) (PPO) extracted from yacon roots (Smallanthus sonchifolius) was partially purified by ammonium sulfate fractionation and separation on Sephadex G-100. The enzyme had a molecular weight ...
Antioxidant properties of the alkaloid boldine in systems undergoing lipid peroxidation and enzyme inactivation
(1991)
Boldine, in low micromolar concentrations, was able to prevent brain homogenate autooxidation, the 2,2'-azobis(2-amidinopropane)(AAP)-induced lipid peroxidation of red cell plasma membranes, and the AAP-induced inactivation ...
Inactivation kinetics of polyphenol oxidase and peroxidase in green coconut water by microwave processing
(ELSEVIER SCI LTD, 2008)
The inactivation kinetics of enzymes polyphenol oxidase (PPO) and peroxidase (POD) was studied for the batch (discontinuous) microwave treatment of green coconut water. Inactivation of commercial PPO and POD added to sterile ...

Immobilization and stabilization of a bimolecular aggregate of the lipase from Pseudomonas fluorescens by multipoint covalent attachment
(2013-01-01)
The soluble lipase from Pseudomonas fluorescens (PFL) forms bimolecular aggregates in which the hydrophobic active centers of the enzyme monomers are in close contact. This bimolecular aggregate could be immobilized by ...
Effectiveness inactivation of trypsin inhibitor fron brazilian cultivarof beans (Phaseolus vulgaris L.)
(2011)
The trypsin inhibitor, an antinutritional factor, which is abundant in dycotiledoneous and monocotyledoneous, is usually inactivated by heating treatment. The infl uence of pressure-cooking (121°C and 141kPa) for 30 min on, ...
