Direct extraction methods for the quantitation of sterols and steryl esters (SE) in foods, beverages and concentrates as free sterols (trimethylsilane ether derivatives) by gas chromatography with flame ionization detection (GC/FID) are introduced. T

A common detector for the analysis of sterols and sterol concentrates by gas chromatography is the flame ionization detector (FID). The detector measures the response of ions from a molecule as it is pyrolyzed in a hydrogen flame. The response is rel

Supercritical fluid extraction (SFE) was used as a primary method to determine the oil content of copra and its meal. Determination of the oil content of copra takes 9 h, and for meal 6 h are necessary with Soxhlet extraction, whereas SFE determined

An improved reversed-phase (RP) method has been developed for the analysis of triacylglycerols (TAG) in fats and oils. This method has shown superior performance over traditional reversed-phase liquid chromatographic (LC) methods in speed and resolut

Oleic acid esterified propoxylated glycerol (EPG-08 oleate) and trioleylglycerol were heated separately (192 ± 8 °C for 12 h/day) until the polymer content was ≥20% and examined. Supercritical fluid fractionation (SFF) produced a monomer fraction
