In this study, the use of chitosan prepared in different solvents (acetic acid, lactic acid) as a coating material was researched. The lowest mean pH, TBARS and TVB-N values among the treatment groups were observed in the acetic acid group. Similarly, the lowest growth of aerobic, lactic acid and Pseudomonas bacteria was recorded in this group. The growth of aerobic bacteria in the fillets that...

Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) was used to identify species-specific water soluble proteins and salt soluble proteins bands of raw fillets, surimi, sausage and different combinations (1:1; 3:1; 1:3; and 4:1) of surimi mixtures; sausage mixtures from the two species of fish, threadfin bream (Nemipterus japonicus), and bulls-eye (Priacanthus hamrur). 7.5% SD...

Multispectral imaging has been evaluated for characterization of the concentration of a specific cartenoid pigment; astaxanthin. 59 fillets of rainbow trout, Oncorhynchus mykiss, were filleted and imaged using a rapid multispectral imaging device for quantitative analysis. The multispectral imaging device captures reflection properties in 19 distinct wavelength bands, prior to determination of ...

The authors consider the possibility of using low-value pelagic fish species in diet people with restrictions on consumption nitrogenous extractive substances including nucleic acids which are sources purine base metabolism. objects study were chopped mackerel fillets from boiled and raw fish, quick-frozen minced horse industrial processing a form. studies carried out accordance experimental pl...

Sustainable freshwater aquaculture has been recently gaining attention owing to the potential of nourishing world. The study aimed evaluate influence finishing diets on activity 21 genes involved in hepatic lipid metabolism and intestinal homeostasis, liver intestine histology, level eicosapentaenoic (EPA) docosahexaenoic (DHA) acids common carp fillets. We compared two experimental diets: cont...

Different modified atmosphere conditions with various CO2 concentrations on microbial load (psychrophile, mesophile aerobic and anaerobic bacteria) and physico-chemical properties of barramundi (Lates  calcarifer Bloch) fillets stored at 8°C were compared to determine the best packaging conditions. The gas conditions evaluated were 100% CO2 (M1), 75% CO2/25% N2 (M2), 50% CO2/50% N2 (M3), 25% CO...

Monola oil, a high oleic acid canola cultivar, and canola oil were evaluated as replacers of fish oil at three levels of inclusion (60%, 75% and 90%) in rainbow trout diets. After a 27-week grow-out cycle, the diet-induced effects on growth, fatty acid metabolism and final eating quality were assessed. Overall, no effects were noted for growth, feed utilisation or fish biometry, and the fatty a...

Polycyclic aromatic hydrocarbons (16 EPA list) were determined in oils, fish feed, and fillets from gilthead sea bream fed through a full production cycle (14 months) with feed containing different proportions of fish oil replaced by vegetable oils, followed by a finishing phase with fish oil. At the beginning of the study, fish presented 46.6 microg/kg fresh weight of the sum of PAHs in fillet...

In recent years, there has been an increasing interest in using food additives from natural sources to improve taste and also extend the shelf-life of semi-preserved foodstuffs. The aim of this study was to examine the chemical and microbiological changes promoted by a local marinating process in rainbow trout fillets during chilled storage. Fish fillets were immersed in marinades and stored at...

For it, horse mackerel (Trachurus trachurus) fillets were soaked in water (Water Control) and two RP concentrations (0.333%, RP-1; 1.333%, RP-2) and compared to untreated fillets (Blank Control). Fluorescence detection and thiobarbitu...
