Wax composition of sunflower seed oils
Waxes are natural components of sunflower oils, consisting mainly of esters of FA with fatty alcohols, that are partially removed in the winterization process during oil refining. The wax composition of sunflower seed as ...
Effectiveness of natural antioxidants in sunflower oil
The antioxidant activity of ∝- and δ-tocopherol, citric acid, ascorbic acid and ascorbyl palmitate was investigated in sunflower oil containing naturally occurring tocopherol. The effectiveness of natural antioxidants in ...
A simple procedure to evaluate the performance of fats and oils at frying temperatures
(Inst Grasa Sus DerivadosSevilleEspanha, 1997)
Antioxidant effect of poleo and oregano essential oil on roasted sunflower seeds
(Wiley Blackwell Publishing, Inc, 2013-12)
The objective was to evaluate the stability of sensory and chemical parameters in roasted sunflower seedssupplemented with oregano and poleo essential oils; and the consumer acceptability of this product. Four samples ...
Sunflower oil methanolisys and glycerol ketalisation: Stepwise production of biofuels and additives with 3-methylimidazolium hydrogensulphate as catalyst
The ionic liquid 3-methylimidazolium hydrogensulfate is soluble within the glycerol phase that it creates, after catalyzing the transesterification of sunflower oil to fatty acids methyl esters with methanol. Separation ...
Characterization of waxes and residual oil recovered from sunflower oil winterization waste
(Wiley VCH Verlag, 2016-05-17)
Two filter cakes from the sunflower oil winterization process were used to recover, fractionate and characterize their oil and wax fractions. Both samples presented high lipid content (75.35 and 58.21% dry basis) composed ...
Extraction of sunflower oil using ethanol as solvent
The ethanolic extraction of oil from sunflower collets was studied and compared with previous data where hexane was used as extraction solvent. First, the extractive power of ethanol was determined by Soxhlet. It gave a ...
Changes in Composition and Quality of Sunflower Oils during Extraction and Degumming
(Instituto de la Grasa, 2000-04)
The influence of different stages of processing on composition and quality of crude sunflower oil was studied through the determination of fatty acids, metal and phosphorus contents, free fatty acids, peroxide and anisidine ...
Influence of spray-drying operating conditions on sunflower oil powder qualities
(Elsevier Science Sa, 2014-01)
The main aim of the study was to develop a vegetable oil (VO) microencapsulation process using a spray drying technique with the aid of the response surface methodology (RSM). The specific objectives were to evaluate ...
Preferences for sunflower oil produced conventionally, produced with nanotechnology or genetically modified in the Araucanía Region of Chile
(agricultural aconomics, 2013)
In light of the increasing use of nanotechnology in food production, consumer acceptance of sunflower oil produced with nanotechnology or from genetically modified (GM) plants and the conventionally produced raw materials ...
