Vidrih R., Vidakovič S., Abramovič H. (2010): Biochemical parameters and oxidative resistance to thermal treatment of refined and unrefined vegetable edible oils. Czech J. Food Sci., 28: 376–384. In human nutrition fats are physiologically important food constituents but also the components most liable to oxidative degradation. The oils included in the study were refined (sunflower, extra-sunfl...

BACKGROUND The objective was to determine the effect of prepartum diets supplemented with rolled canola seed (high in oleic acid) or sunflower seed (high in linoleic acid) on luteinizing hormone (LH) pulsatility and gonadotropin releasing hormone (GnRH)-induced LH release during early postpartum. METHODS Thirty-one pregnant Holstein cows, blocked by body condition score, parity and expected c...

The fatty acids, cholesterol compositions and the ratio between unsaturated saturated acids are important parameters for determination of nutritional value certain oils. Most oils sold in our markets claimed they cholesterol- free their acid profile is unknown. To determine commercially vegetable three places, twelve oil samples were analyzed compositions. Cholesterol was detected most sample e...

The impact of chemical desiccation on yield showed contrasting results depending on seedmoisture content at the time of application. Its effects on seed deterioration are still unknownand could be modified by seed composition. Objectives were to evaluate the impact of chemicaldesiccation on: i) hybrid sunflower seed yield and composition at harvest time, ii) seeddeterioration during long-term s...

Argentina is the world's leading exporter of confectionery sunflower. This work characterized morphometric and nutritional composition sunflower seeds from new genotypes. Average variables per seed were: weight 0.11 0.06 g with without achene, respectively; length 15.2 mm; width 8.50 mm, most calibers greater than 9.51 mm. Proximate analysis indicated that shell were an important source lipids ...

The core objective of this study was to investigate the physicochemical characteristics and fatty acid composition oils sunflower, olive, virgin coconut ginger oils, as well separation their unsaturated acids. data indicated a significant variation in properties (acid, saponification, ester, iodine values) among oils. Transesterification process carried out at molar ratio 1:7:0.1 oil: methanol:...
