one of the simplest methods for short-term handling and storage of fish is the refrigeration in combination with dip treatments. this study was conducted to determine the effect of pre-storage α-tocopherol acetate dipping treatments on lipid stability of refrigerated rainbow trout fillets. trout fillets were dipped in α-tocopherol acetate solutions (200 and 500 mg kg-1 flesh) and subsequently s...

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...

two batches of frankfurters containing about 55% chicken meat with two different oils (including canola and soybean) were manufactured. batch 1 included canola oil and batch 2 included soybean oil in the products. various analyses were performed to detect the lipid changes of both batches during storage. fatty acid composition analysis using gas chromatography showed little change in the fatty ...

A fully randomized experimental design, with three hundred and fifty-one days-old Japanese quails located into the seven treatment groups five replicates ten quail each were used in current study. The treatments whereas basal diet basis corn soybean meal (100 200 and) of vitamin E, sesamine thymoquinone. At end study (35 days old) two from pen selected, weighted, slaughtered. carcass percentage...

Edible films and coatings offer great potential to support sustainable food production by lowering packaging waste, extending product shelf life, actively preserving quality. Using edible containing plant extracts with antioxidant antibacterial characteristics could help enhance the quality life of fish products. In this study, combination effect chitosan beetroot, curcumin, garlic on biogenic ...

background: due to high content of unsaturated fatty acids, trout is susceptible to oxidative spoilage. in this study, the effects of thymus vulgaris essential oil (eo) and extract on oxidative stability of cooked rainbow trout fillet during four months frozen storage period were investigated. methods: three groups of fish fillets were treated with thyme eo and three other groups were treated w...

The scarcity of conventional feed resources and their high price has necessitated exploring cost effective non-conventional ingredients to be utilized to replace the conventional ones like hatchery waste (HW). The chemical composition of HW has revealed its nutrient composition especially higher level of fat (1821%), which pose threat to spoil the quality of of product through rancidity. Hatche...

Considering the importance of cutaneous tissue investigation and need for development new protocols to non-invasively establish safety efficacy dermocosmetics topical products, we aimed at developing an HPLC-TBARS-EVSC (high performance liquid chromatography–thiobarbituric acid reactive species–ex vivo stratum corneum) assay lipid peroxidation measurement on subjects’ corneum (SC) obtained by t...
