The present work was carried out to study the effect of vacuum packaging and pomegranate peel extract (PE) treatments on the quality of pacific white shrimp (Peneous vannamei) during refrigerated storage. Changes in pH, thiobarbituric acid (TBA), total volatile base nitrogen (TVB-N), trimethylamine (TMA), aerobic plate counts, psychrophilic, lactic acid bacteria and enterobacteriaceae counts, m...

Effect of sodium alginate coating enriched with horsemint essential oil (HEO) on the quality of bighead carp (Aristichthys nobilis) fillets at refrigeration temperature (4 ± 1°C) was studied. Bighead carp fillets were coated with neat sodium alginate (SA) and sodium alginate containing 0.5 and 1% v/v of HEO and their quality changes in terms of total volatile basic nitrogen (TVB-N), peroxide va...

In the present study, methanol and aqueous extracts of Parkinsonia aculeata L. leaves were prepared and analyzed for phytochemical analysis and antioxidant potential in different in vitro assays. Antioxidant activity was studied using DPPH, CUPRAC, reducing power assay, deoxyribose degradation (site and nonsite specific), ferric reducing antioxidant potential (FRAP), ferric thiocyanate (FTC), t...

The radical-scavenging activities of two thiols, eight (thio)barbituric acid derivatives and six chain-breaking phenolic antioxidants were investigated using the induction period method for polymerization of methyl methacrylate (MMA) initiated by thermal decomposition of 2,2’-azobisisobutyronitrile (AIBN) and monitored by differential scanning calorimetry (DSC). The induction period (IP) for th...

The effect of adding 0.05% natural herb extracts obtained from rosemary (Rosmarinus officinalis), thyme (Thymbra spicata), and basil (Ocimum basilicum L.) on mackerel balls during 10 months frozen storage (-18oC) were investigated concerning sensory (raw cooked), biochemical (PV- peroxide value, FFA- free fatty acids, TVB-N -total volatile basic nitrogen, TBA- thiobarbituric acid pH) microbiolo...

It has been proposed that a ring-opened form may be responsible for the toxicity of benzene. The present studies demonstrate that incubation of [14C]benzene with liver microsomes (obtained from male CD-1 mice treated with benzene) in the presence of NADPH results in the formation of a ring-opened product. Evidence for the identity of this product was obtained by derivatizing with 2-thiobarbitur...

The nutritive compositions and oxidative stabilities of processed avocado pastes at ambient (30±1 ̊C, RH80%) and refrigerator (5-6 o C) storage temperatures were evaluated and studied. Avocado pulp was blended with ingredients, chilled, kneaded and shaped. For oxidative studies varying concentrations and combinations of Ascorbyl palmitate (AP) and Propyl gallate (PG) were blended with the pulp. ...

Lipid peroxides were measured in cerebrospinal fluid (CSF) and sera from patients with multiple sclerosis (MS) or other conditions and from control subjects. In serum, visible fluorescence, A240nm, and free and protein-bound thiobarbituric acid (TBA)-reactive substances were significantly greater in MS patients than in control subjects. No such differences were observed in CSF. There was no cor...

The study was aimed to evaluate the antioxidant activity of Cassytha filliformis for the first time. The antioxidant activity of cassytha filiformis extracts in hexane, ethyl acetate and methanol were assessed based on their radical scavenging activity (RSA) using the DPPH assay. Methanolic extract showed good antioxidant activity when compared with standard Butylated hydroytoluene(BHT). Furthe...
