Enzymatic browning in foods and its prevention
(Nova Science Publishers, 2009)
Phenolic compounds are widely distributed in the plant kingdom and are considered to be secondary metabolites. Structurally they contain an aromatic ring bearing one or more hydroxyl groups, together with a number of other ...
The rheological properties of Turkish delight
(Berkeley Electronic Press, 2008)
In the food industry, rheological properties, such as viscosity, shear rate, and shear stress, are the most important parameters required in the design of a technological process. Therefore, in this study, we determined ...
Inhibition kinetic of Ocimum basilicum L. polyphenol oxidase
(Walter De Gruyter Gmbh, 2007)
The paper reports the inhibition model of the purified polyphenol oxidase (PPO) activity from basil (Ocimum basilicum L.) with L-cysteine, ethylenediaminetetraacetic acid (EDTA), ascorbic acid, gallic acid, D,L-dithiothreitol, ...
Adsorption kinetics of victoria blue onto perlite
(Parlar Scientific Publications (P S P),, 2003)
The effects of various experimental parameters such as initial dye concentration, temperature and pH on adsorption capacity of victoria blue on perlite have been investigated. The extent of dye removal increased, with the ...
Variations of peroxidase activity among Salvia species
(Elsevier Sci Ltd, 2007)
Peroxidase was partially purified from Salvia species such as Salvia tomentosa Miller, Salvia virgata Jacq and Salvia viridis L. using solid (NH4)(2)SO4 precipitation and dialysis methods. We investigated the effect of ...
Adsorption of methylene blue onto hazelnut shell: Kinetics, mechanism and activation parameters
(Elsevier Science Bv, 2009)
The adsorption kinetics of methylene blue (MB) on the hazelnut shell with respect to the initial dye concentration, pH, ionic strength, particle size and temperature were investigated. The rate and the transport/kinetic ...
Partial characterization of peroxidase from the leaves of thymbra plant (Thymbra spicata L. var. spicata)
(Springer, 2007)
Peroxidase (EC 1.11.1.7; donor: hydrogen-peroxide oxidoreductase) catalyses the oxidation of various electron donor substrates (e.g. phenols, aromatic amines). In this study, the peroxidase was extracted from Thymbra spicata ...
Some kinetic properties of polyphenol oxidase from Thymbra spicata L. var. spicata
(Elsevier Sci Ltd, 2006)
Polyphenol oxidase (PPO)of Thymbra (Thymbra spicata L. var. spicata) was isolatedby (NH4)(2)SO4 precipitation and dialysis. A diphenolase from Thymbra plant, active against 4-methylcatechol, catechol and pyrogallol was ...
Surface properties of poly(vinylimidazole)-adsorbed expanded perlite
(Elsevier Science Bv, 2006)
Adsorption, electrokinetic properties and the interactions between polymer and clay minerals have recently received much attention, owing to the physicochemical properties of these materials. In this study, surface properties ...
Electrokinetic and adsorption properties of sepiolite modified by 3-aminopropyltriethoxysilane
(Elsevier Science Bv, 2007)
Surface modification of clay minerals has become increasingly important for improving the practical applications of clays such as fillers and adsorbents. An investigation was carried out on the surface modification of ...
