The article presents the possibility of using waste oil obtained by repeatedly frying fish, and it in process fattening karakul. main properties purified were determined an IR spectroscopic analysis was carried out. Bleached is used emulsion greasing karakul with soft, smooth elastic leather tissue. KEY WORDS: karakul, fatliquoring, oil, emulsifier, material, acid number, vegetable oils.

There is a mounting concern about the intake of foods containing trans fatty acids (TFA) due to their deleterious effects on human health, mainly on the cardiovascular system. In this way, it is important to consider the processes that form TFA in foods, and the alternatives to minimize them. Among the processes that result in the formation of TFA, the hydrogenation of vegetable oils stands out...

Background & Aims of the Study: The quality of the edible oils is made with chemical compositions and percentage of  the degree of unsaturation fatty acids. The peroxide value (PV) always measures the extent of primary oxidation (rancidification) of oils. Oils Rancidity can produce potentially toxic compounds associated with health effects such as heart and neurological disorde...

Over the past three decades, biodiesel has experienced remarkable development. This fuel, obtained from vegetable oils or animal fat, advantage of being renewable, less polluting, and reduces energy dependence oil-importing countries.In this article, we are interested in production a biofuel based on non-food used frying oil. The physico-chemical characteristics for Oleor oil found to comply wi...

The study aimed to investigate the influence of repeated frying processes potatoes in a fryer on acrylamide content French fries. For deep-frying, Asinaria variety, sunflower and palm oils were used. each oil type, five cycles at 170°C, for 6 min performed final product was analyzed using solid phase extraction (SPE) technique GC-MS/MS method. increased case first three cycles, while it fourth ...

Fatty acid methyl ester (FAME) or biodiesel is a biofuel conventionally produced from edible oil and methanol, using an alkaline catalyst, through a transesterification reaction. As FAME is mostly produced from edible vegetable oils, crop soils are used for its production, increasing deforestation and producing a fuel more expensive than diesel. In addition, between 70 and 80% of the total FAME...
