Hot-smoked rainbow trout (Oncorhynchus mykiss) fillets with vacuum packaging are an important export source and the manufacturers recommend a shelf life of 21 d at 4 °C. This time is very short in terms packaged foods. In this study, nisin lysozyme (0.5 1% w/v, respectively) were used order to prolong hot-smoked by adding them brine (8–10 ˚C, 10 h). Five treatment groups formed, including contr...

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...

effects of catechin for preventing black spots forming in whiteleg shrimp (litopenaeus vannamei) were evaluated. for processing whole shrimp, catechin was used at a concentration of 0.2 and 0.3 % for 15 minutes. sodium metabisulfite was used at a concentration of 3 % for 10 minutes as control samples. without antioxidant shrimp were used as control samples too. treatments quality was evaluated ...

Abstract Rabbit meat is one of the most consumed meats throughout world and extremely susceptible to spoilage due its high protein moisture content. Natural preservatives with antioxidant antibacterial properties are needed maintain quality increase shelf life. This study examined effect 1% chitosan (CH), 0.2% rosemary ( Salvia rosmarinus ) essential oil (REO), their combination on pH, total vo...

The present study aims to utilize the poultry wastes (heads & legs of chicken) in production protein concentrate. chemical contents and functional properties final processed product were evaluated. method had been used concentrate processing which included digestion raw materials with 5 % HCl at pH 4. composition dried refusals 46.38% ( N×6.25), 22.34 fat 8.46 ash, while that for processed....

abstract in this study, big-head carp flesh was processed and fish finger was produced by the formula of 1, 2 and 3 with 70, 80 and 93.5 percent of big head fish flesh respectively. then sensory attributes, biochemical changes and nutritional value such as peroxide value (pv), thiobarbituric acid (tba) and the total volatile nitrogen (tvb-n) changes and microbial load of all three formulas were...

Quality and shelf-life of whole and filleted Coryphaena hippurus, stored with modified atmosphere packaging (MAP) and natural antioxidants from halophytes (HAL), were investigated. Fillets were divided into control, simply sealed in trays; MAP, preserved by modified atmosphere (45% CO2, 50% N2, 5% O2); and MAP-HAL, pretreated with antioxidants and preserved by MAP. Whole and filleted fish were ...
