Phase Transition of Sunflower Oil as Affected by the Oxidation Level
Journal of the American Oil Chemists' Society - Tập 85 - Trang 591-598 - 2008
The influence of the oxidation level on the phase transition behavior of sunflower oil was evaluated by differential scanning calorimetry (DSC) and synchrotron X-ray diffraction (XRD) at both small and wide angles. The crystallization was monitored at a cooling/heating rate of 2 °C/min from 20 to −80 °C and vice versa applying both techniques. The triacylglycerols organize in two double-chain leng...... hiện toàn bộ
Enrichment of polyunsaturated fatty acids from sardine cannery effluents by enzymatic selective esterification
Journal of the American Oil Chemists' Society - Tập 77 - Trang 329-332 - 2000
The sardine canning industry produces vast quantities of effluents that need expensive reprocessing. Their oily component contains valuable n−3 polyunsaturated fatty acids, namely EPA (5,8,11,14,17-eicosapentaenoic acid) and DHA (7,10,13, 16,19-docosahexaenoic acid), up to 10% each. Our aim was to develop a process allowing the recovery of these fatty acids. After removing solid particles, protein...... hiện toàn bộ

Process conditions affect pigment quality and yield in extracts of purple sunflower hulls
Journal of the American Oil Chemists' Society - Tập 72 - Trang 183-188 - 1995
Extract of purple sunflower hulls is a potential red food colorant; however, suitable process conditions must still be identified. Selected process variables were studied using bench-scale units to prepare, clarify, concentrate and spray dry extracts. Concentration by evaporation at 32°C and addition of maltodextrin to 15% (wt/dry wt) prior to drying largely eliminated pigment degradation during t...... hiện toàn bộ
Characterization of triglycerides isolated from jojoba oil
Journal of the American Oil Chemists' Society - Tập 77 - Trang 1325-1329 - 2000
Triglyceride compounds isolated from jojoba seed oil by column chromatography were composed predominantly of C18′ C20′ C22′ and C24 n−9 fatty acids with minor amounts of saturated C16. Chain length and double-bond positions were determined by gas-liquid chromatography and gas-liquid chromatography-mass spectrometry of the corresponding methyl ester and picolinyl ester derivatives. Triglyceride str...... hiện toàn bộ
Lipids in soil
Journal of the American Oil Chemists' Society - Tập 43 - Trang 203-210 - 1966
As much as 20% of soil humus occurs in the form of lipids. High values are characteristic of Podzol soils and highmoor peats. Lipids of the following types are known to be present: paraffin hydrocarbons, phospholipids, fats, waxes, fatty acids, and terpenoids. A long list of compounds have been reported; the identification of many of them require confirmation using modern analytical techniques. So...... hiện toàn bộ
