A twin‐screw extruder for oil extraction: II. Alcohol extraction of oleic sunflower seeds
Journal of the American Oil Chemists' Society - - 1999
Corinne Dufaure, Zéphirin Mouloungui, Luc Rigal
AbstractOur work is about the extraction of sunflower seed oil in a twin‐screw extruder with or without the injection of 2‐ethylhexanol and acidified 2‐ethylhexanol. 2‐Ethylhexanol is mixed with phosphoric acid. The oil recovery is increased to 90% by the co‐injection of acidified alcohol. Mixing phosphoric acid with the alcohol enhances the lability of the oily sp...... hiện toàn bộ

Recent advances in the analytical chemistry of fatty acids and derivatives
Journal of the American Oil Chemists' Society - Tập 56 - Trang 819A-822A - 1979
L. D. Metcalfe
Recent advances in the analysis of industrial fatty acids and their derivatives almost always involve complex instrumentation. One of the most important developments in the analysis of fatty acids and their derivatives was the application of gas chromatography (GC). The result has been so effective that the time-consuming fractional distillation and detailed analysis of fractions previously employ...... hiện toàn bộ

Production of free fatty acids in safflower seeds by fungi
Journal of the American Oil Chemists' Society - Tập 55 - Trang 465-468 - 2013
T. C. Heaton, P. F. Knowles, D. S. Mikkelsen, J. E. Ruckman
In 1975, free fatty acids (FFA) reached 0.50% in hand-sampled seeds (achenes) from the Sacramento Valley but never exceeded 0.10% in samples from the San Joaquin Valley. High levels of FFA in safflower seeds from the Sacramento Valley were attributed to seed-borne fungi, especiallyAlternaria sp., having a lipolytic action on safflower oil. Greenhouse inoculations on representative safflower cultiv...... hiện toàn bộ
Periodate-permanganate oxidations. IV. Determination of the position of double bonds in unsaturated fatty acids and esters
Journal of the American Oil Chemists' Society - Tập 33 - Trang 126-128 - 1956
E. von Rudloff
The reaction of the periodate-permanganate reagent with unsaturated fatty acids, including oleic, elaidic, eicosenoic, 10-undecenoic, and linoleic acids proceeded smoothly to give the expected end-products in quantitative yields. The latter were conveniently isolated and determined by partition chromtography on silicic acid columns in 10 to 100 mgm. quantities. Some compounds, which were unreactiv...... hiện toàn bộ
Isolation of Pure Phospholipid Fraction from Egg Yolk
Journal of the American Oil Chemists' Society - Tập 89 Số 1 - Trang 179-182 - 2012
Witold Gładkowski, Anna Chojnacka, Grzegorz Kiełbowicz, Tadeusz Trziszka, Czesław Wawrzeńczyk
AbstractThe phospholipid (PL) fraction from egg yolk was isolated and purified. In the procedure applied (method 2) the egg yolk was extracted with ethanol, precipitated using acetone chilled to −20 °C and washed using acetone. The purity of the samples was checked by HPLC analysis using a Charged Aerosol Detector (CAD). The results were compared with those obtaine...... hiện toàn bộ
Comparison of High-Pressure Behavior of Physicochemical Properties of the Di- and Triacylglycerols Established by Ultrasonic Methods
Journal of the American Oil Chemists' Society - Tập 94 - Trang 1261-1268 - 2017
A. Balcerzak
Two samples of triacylglycerols i.e., olive oil and triolein, and one sample of diacylglycerol were investigated. In the course of compression, the density of the samples was determined by measurements of the change of piston position in a pressure chamber and volume correction due to chamber expansion under pressure. The speed of sound was evaluated from the time of flight of an ultrasonic impuls...... hiện toàn bộ
Characterization of Turkish Olive Oils by Triacylglycerol Structures and Sterol Profiles
Journal of the American Oil Chemists' Society - Tập 91 - Trang 2077-2090 - 2014
Aslı Yorulmaz, Huseyin Yavuz, Aziz Tekin
A characterization study of Turkish monovarietal olive oils using chemical variables such as fatty acid, sn-2 fatty acid, triacylglycerol, and sterol composition is presented. A total of 101 samples of Olea europaea L. fruits from 18 cultivars were collected for two crop years from west, south, and southeast regions of Turkey. Olives were processed to oil and olive oil samples were evaluated for t...... hiện toàn bộ
