fatty acids play important roles in biological systems and the newborns fatty acids requirements are covered only by the milk. it is of particular interest to qualify the content of the fatty acids in the milk. this study was performed to determine the levels of some fatty acids in the infant formulas and also to describe a method without derivatization for the fatty acids analysis and applying...

Approximately one-third of all food produced for human consumption worldwide is wasted. The current waste management practices are not only costly but also have adverse impact on environment. In this study, black soldier fly (BSF) (Hermetia illucens) larvae were grown on food wastes to produce fat and protein-rich BSF prepupae as a novel strategy for efficient organic waste management. The lipi...

The aim of the present study was to determine and compare the seasonal changes in the proximate composition, fatty acids profile and fat soluble vitamins content in spring and autumn goby (Neogobius melanostomus) caught from the Bulgarian Black Sea waters. The proximate composition (moisture, protein and total lipid) has been determined according to AOAC (1990).  Analysis of fatty acid methyl e...

Fifty-four Holstein bulls were blocked by initial BW (301 +/- 7.4 kg) and randomly assigned to 6 treatments following a 3 x 2 factorial arrangement, with 3 concentrate lipid levels (5, 8, and 11% of DM) and 2 lipid sources (whole canola seed and whole linseed), with the objective of evaluating the possibility of increasing the content of n-3 fatty acids in meat. Concentrates (mostly corn meal) ...

The study was conducted to evaluate the effects of different dietary oil sources supplementation on laying hens’ performance and fatty acids profile of egg yolks. Seventy-two 23-week-old laying hens (Tetra-SL) divided into six experimental diets (four replicates and three birds per replication) in a completely randomized design for nine weeks. Experimental diets were included: 1) control (no oi...

The present work was conducted to investigate the chemical composition (amino acid, mineral content, and lipid profile) of bones from three different Iranian pelagic fish species. The biochemical composition of Sardinella gibbosa, Clupeonella engrauliformis and Stolephorus indicus bones captured from the Iranian Ocean (the Oman Sea and Caspian Sea) were determined. The analysis of amino acids a...

in this research, the quality indices, phenolic compounds (hydroxy tyrosol, tyrosol, cinamic and vanilic acid), fatty acids and pigments from olive oil of cultivars ‘zard’, ‘roghani’, and ‘mari’ (from kazeroon region, located in fars province), were assessed. measurement of phenolic compounds showed that ‘mari’ cultivar oil contained the highest cinamic and vanilic acids with 1.4 and 1.18 milli...

Two protocols were performed to study meal fatty acid metabolism. In protocol 1, 14 patients scheduled for elective intra-abdominal surgery (11 undergoing bariatric surgery for severe obesity) consumed a meal containing [3H]triolein in the evening before surgery. This allowed us to measure adipose tissue lipid specific activity (SA) in mesenteric and omental, deep and superficial abdominal subc...

The proximate composition, amino acids and fatty acids composition in the muscle of wild, inshore and offshore cage-cultured large yellow croaker, Pseudosciaena crocea (Richardson, 1846), were determined to identify nutritional differences. Wild fish groups showed highest content of moisture and crude protein, but the lowest lipid content. Offshore cage-cultured fish showed significantly higher...
