in this study, antioxidant activity of kolkhung skin oil, baneh skin oil and seasame oil were compared. the ratio between polyunsaturated to saturated fatty acids (pufa/sfa) of kolkhung skin oil, bane skin oil and seasame seed oil were 0.52, 0.26 and 3.06, respectively. total phenolic contents of kolkhung skin oil, bane skin oil and seasame seed oil were 99.67, 645.73 and 81.72 mg/kg, respectiv...

Palm oil and soybean oil are the 2 most widely used cooking oils in the world. Palm oil is consumed mainly in developing countries, where morbidity and mortality due to cardiovascular disease (CVD) are on the rise. Although claims about adverse or protective effects of these oils are commonly made, there are no epidemiologic studies assessing the association between these oils and cardiovascula...

This study evaluated the suitability of canola and flaxseed oils as source of supplemental dietary lipid for fingerlings of rainbow trout. Triplicate groups of the 30 fingerlings were fed twice daily by iso-nitrogenous, and iso-calorific diets for 8 weeks. Experimental diets consisted of 30.2% protein, 18.6 kJ/g energy and 16.6% lipid from fish oil, canola oil, flaxseed oil, 1:1 blends of fish ...

The addition of vegetable oils to the diets of dairy goats is an alternative to supplemental feeding during the dry period and improves the lipid profile of milk and by-products. Cheeses were produced using milk from cross bred goats (Saanen×Alpina) fed diets enriched with 4% vegetable oil (faveleira, sesame or castor), the fatty acid profile of cheeses was studied. Supplementation with vegetab...

The oils of some unconventional oilseeds (hemp, radish, terebinth, stinging nettle, laurel) were obtained by a cold-press method in which the total oil content, fatty acids, tocopherol isomers, some metal contents (Ca, Mg, Fe, Cu), antioxidant activity and oxidative stability were determined. The total oil content was determined ranging between 30.68 and 43.12%, and the oil samples had large am...

olive oil is one of the oldest known vegetable oils, ranking sixth in world production. since it is extractedfrom fresh fruit and used without aging, the conditions of oil production are very important. during theextraction of virgin olive oil, the milling and malaxation steps are vital for increasing oil yield and quality.in this study, the effect of milling (single or double), temperature of ...

The purpose of this project is to propose a quick and environmentally friendly alternative to measure the quality of oils used in food industry. There is evidence that repeated and indiscriminate use of oils in food processing cause physicochemical changes with formation of potentially toxic compounds that can affect the health of consumers and cause organoleptic changes. In order to assess the...

Conjugated linoleic acid (CLA) is found in small quantities in dairy and beef products. Obtaining optimum dietary CLA levels from these sources requires an increased intake of saturated fat. A 20% CLA soy oil was produced by UV photoisomerization of soy oil linoleic acid (LA), which is naturally low in saturated fat, but no other high-LA vegetable oils have been studied for their potential as C...

this study was conducted in order to evaluate the effect of thyme (thymus vulgaris l.) and oregano (oreganum vulgare l.) essential oils on performance, carcass characteristics, antioxidant status and blood biochemical parameters in broiler chickens. a total of 216 as-hatched broilers (ross-308) were divided into 6 treatments with 3 replications of 12 birds per each. experimental treatments were...
