A thiobarbituric acid (TBA) reaction for measuring lipid peroxidation products was evaluated for interference by several ingredients commonly used in solutions to prepare or analyze tissue homogenates or subcellular organelles. These included sucrose (up to 100 mM final concentration in the assay medium), Tris-maleate (up to 40 mM), imidazole (up to 20 mM), inorganic phosphate (up to 10 mM), an...

AIM The present study was conducted to determine efficacy of edible coating of carrageenan and cinnamon oil to enhance the shelf life of chicken meat stored under refrigeration conditions. MATERIALS AND METHODS Chicken breast was coated with carrageenan and cinnamon oil by three methods of application viz., spraying brushing and dipping. The coated meat was evaluated for drip loss, pH, thioba...

This assay of plasma lipoperoxides involves hydrolysis in dilute H3PO4 at 100 degrees C; complexation of malondialdehyde (MDA), a hydrolysis product, with thiobarbituric acid (TBA); methanol precipitation of plasma proteins; fractionation of the protein-free extract on a C18 column; and spectrophotometric quantification of the MDA-TBA adduct at 532 nm. The detection limit was 0.15 mumol of MDA ...

Pistachio as a strategic product has a particular position among Iranian productions and is one of the most important non-oil exports after carpet. In this study, after primary processing such as dehulling, washing, drying and roasting, pistachio nuts were packed in four different atmospheres including N2, CO2, vacuum and ambient air. Storage temperatures were 20 C and 40 C for a 12 month perio...

AIM To investigate the antioxidant and hepatoprotective effects of Cortex Dictamni aqueous extract (CDAE) in carbon tetrachloride (CCl4)-induced liver damage in rats. METHODS The in vitro antioxidant effect of CDAE was investigated using α,α-diphenyl-β-picrylhydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), β-carotene bleaching, reducing power, and thiobarbituric...

this study was carried out to evaluate how various amounts of nanozeolite decrease the effects of aflatoxins (af) on color and oxidative stability of the broiler thigh meat. three hundred and thirty six one-day-old ross 308 male broiler chickens were divided into six groups including a control group, which received diet without af and nanozeolite, and five treatment groups that received diet wi...

INTRODUCTION Bluetongue (BT) is a non-contagious infectious disease of ruminants. The disease agent bluetongue virus (BTV) is classified in the Reoviridae family Orbivirus. AIMS AND OBJECTIVES The aim of this study was to determine serum malondialdehyde (MDA), total antioxidative stres (TAS), total sialic acid (TSA), ceruloplasmin, triglyceride, alanine aminotransferase (ALT), aspartate amino...

The purpose of this study was to determine the effects of using different amounts of potato puree (PP) (10 or 20%) and 10% bread crumbs (BC) as an extender and also control samples (C) with no added extender on chemical composition, energy values, cooking analyses, colour measurements, water holding capacity (WHC), penetration values, thiobarbituric acid value (TBA) and sensory analyses of meat...

The effect of fennel extract on the quality of silver carp (Hypophthalmicthys molitrix) fillets, and the possible efficacy of liposomal encapsulation in the improvement of its antimicrobial and antioxidant activity during chilled storage (4 + 1°C) of the fillets were examined over a period of 15 days. Silver carp fillets were treated with pure fennel extract (0.3% and 0.5% w/v) and liposomal en...

This study aimed at determining the effect of chitosan coating on shelf life extension of salmon ( Salmo salar ) fillets. The success of edible coatings depends highly on their effective wetting capacity of the surfaces on which they are applied. In this context in a first stage the surface properties of salmon fillets and the wetting capacity of the coatings on fish were evaluated. In terms of...
