The role of dietary fats and oils in human nutrition is one of the most important areas of concern and investigation in the field of nutritional science. The findings of investigations on this subject have wide-ranging implications for consumers, health-care providers and nutrition educators as well as food producers, processors and distributors. New evidence concerning the benefits and risks a...

The nutritional values of the three Caspian Sea macroalgae species, Cladophora glomerata, Enteromorpha intestinalis and Laurencia caspica were evaluated based on proximate and fatty acid composition. The investigated species demonstrated low lipid composition (0.20±0.03- 1.62±0.26 % DW) and high carbohydrate (21.70±0.17-26.1±1.27%DW) and protein contents (13.34±2.41-28.08±0.51%DW). The as...

To study the effect of salicylic acid (SA) on the amount and quality of oil in different regions of sunflower inflorescence, a factorial experiment was conducted based on randomized complete block design with 3 replications at the University of Mohaghegh Ardabili, Ardabil, Iran. Salicylic acid at concentrations of 0, 0.1, and 0.2 g L-1 were sprayed on whole plant at 3 stages (twice before flowe...

Squids belong to the cephalopod family, which composes more than 5% of the total annual fishing volume of southern Iran as by- products; however, these do not have significant usage in Iran. This product was studied to extract the high-value products, i.e. marine oils rich in unsaturated multiple-band fatty acids from 50kg squid (Loligo loligo) obtained from Chabahar fishing port and transferre...

the lowest lipid levels of capoeta erhani observed in winter and vice versa in summer. the fatty acid composition of the fillets was significantly different among seasons ( p <0.05), while the variations among sexes were not at the same degrees ( p >0.05). the ratios of the unsaturated fatty acids (ufas) were higher than half of the total fatty acids among all seasons. the level of pufa was hig...

objective: to modify yeild of milk fat and to improve fatty acids profile of milk fat with supplementation of the diet with fish oil enrich in omega-3 fatty acids, especially, eicosapentaenoic acid (epa) and docosahexaenoic acid (dha). design: clinical trial. animals: ten dairy cows (treatment group, n=5 and control group, n=5). procedure: different amounts of fish oil were fed to the treatment...

this study was conducted to determine the concentrations of metals (zn, cu, pb, cd and hg) in two commercial fish species of the persian gulf (coast of bushehr province in iran), as well as in the sea waters. the concentrations of metals were determined by using differential pulse anodic stripping voltammetry (dpasv). two selected species were narrow-barred spanish mackerel and tiger tooth croa...

in order to investigate the effects of boron, zinc and sulfur on yield and fatty acid composition of rapeseed(hyola 401 cultivar), an experiment was conducted in rasht province in 2011. a field experiment withcompletely randomized block design was performed with eight treatments in three replications.maximum grain yield (4157.6 kg ha-1) and grain oil (1770.2 kg ha-1) was obtained from s+b+zntre...

abstract this experiment was conducted to study the effect of south-west climatic conditions on quantitative and qualitative of fatty acids in dog rose (rosa canina l.) seeds collected from five regions including: semirom (isfahan province), kiar and gerdbishe (charmahal and bakhtiari province), yasuj and meymand (kohgiluye and boyer ahmad province). oil was extracted using soxhlet apparatus; t...

the effect of kaolin on fruit and oil of olive cv. `zard’ was evaluated in a commercial orchard in fasacity, fars province. mature olive trees cv. `zard’ were sprayed with 0, 3 and 6% kaolin after 60 days, 60and 90 days and 60, 90, 120 days after full bloom. results showed that kaolin concentration and sprayingtime had not significant effects on physicochemical parameters but they had significa...
