The optimization of a gelled oil-in-water emulsion was performed for use as fat replacer in the formulation of ω-3 PUFA-enriched cooked meat products. The linseed oil content, carrageenan concentration and surfactant-oil ratio were properly combined in a surface response design for maximizing the hardness and minimizing the syneresis of the PUFA delivery system. The optimal formulation resulted...

one of the most important aims of aquatic hatcheries is availability to mass produce of daphnia magna as a live food with high nutritional value in the shortest time. in the present study, d. magna fed with two freshwater green algae species, chlorella sp. and scenedesmus obliquus, enriched with different dosages of a mixture b group vitamins (0, 0.5, 1 and 2 ml.l-1) were compared at two stages...

The present study complements recent investigations on the changes in fatty acid content and pattern of liver phospholipids and triglycerides found in 3-depleted rats which, when exposed for 2 weeks to a flaxseed oil-enriched diet, display aggravated liver steatosis, visceral obesity and excess body weight. In the present experiments, the 3depleted rats exposed to the flaxseed oil-enriched diet...

The by-product from tuna processing is a potential source of edible protein. Therefore, it is very important to extract protein from such raw materials for human food. In this study the optimum pH for protein extraction from tuna by-products was optimized by using isoelectric solubilization and precipitation processes. The Response Surface Methodology (RSM) and the single factor model were used...

fish oil is the important fat source in fish nutrition. high demand for fish oil and low global supply arise a need of alternative oils in fish culture. plant oils are a good candidate in this case. the aim of the present study was to compare the efficacy of fish oil and linseed oil on growth and stress resistance of tiger barb ( puntius tetrazona ) larvae. artemia nauplii were enriched by 2.5,...

Tuna processing by-product is estimated at more than 100,000 metric tonnes annually in Iran, which could be a potential source of edible protein in human food. Hence, recovering proteins from tuna by-products is a big achievement in the seafood industry. In this work tuna protein isolates (TPI) were extracted from dark/ red meat using the isoelectric solubilization/ precipitation method. Oxidat...

Gelatinous zooplankton play an important role in marine food webs both as major consumers of metazooplankton and as prey of apex predators (e.g., tuna, sunfish, sea turtles). However, little is known about the effects of crude oil spills on these important components of planktonic communities. We determined the effects of Louisiana light sweet crude oil exposure on survival and bioaccumulation ...

Marine oils are important to human nutrition as the major source of docosahexaenoic acid (DHA), a key omega-3 long-chain (≥C20) polyunsaturated fatty acid (n-3 LC-PUFA) that is low or lacking in terrestrial plant or animal oils. The inclusion of fish oil as main source of n-3 LC-PUFA in aquafeeds is mostly limited by the increasing price and decreasing availability. Fish oil replacement with ch...
