Total phospholipids in crude palm oil: Quantitative analysis and correlations with oil quality parameters

Abstract

Phospholipids, selectively extracted from crude palm oil and free of colored carotenoids, can be quantitatively determined by the phospholipid‐molybdenum blue complex in hexane. A study of the phospholipid in crude palm oil in relationship to other components affecting oil quality shows that they have a beneficial effect while any detrimental effect may be of an indirect nature.

The effects of physical refining on the formation of 3-monochloropropane-1,2-diol esters in relation to palm oil minor components

“…This finding suggests that phospholipids might be one of the precursors of 3-MCPD ester formation, but this hypothesis has yet to be verified. The total phosphorus content measures the total phosphatides present in the oil, including phospholipids and some inorganic phosphates (Goh, Tong, & Gee, 1984). In palm oil, inorganic phosphate accounts for most of the total phosphorus content, while phospholipids are present at only 10-30% of the total phosphorus (Gibon et al, 2007).…”

Analytical characteristics of crude and refined palm oil and fractions

“…There are at least three companies in Malaysia producing refined red palm oil. Carotenoids [7] 500-700 Squalene [8] 200-500 Non-terpenoid hydrocarbons [9] 30-50 a-Tocopherol 1 tocotrienols [7] 600-1000 Sterols [10] 362-627 Triterpenic alcohols [11,12] 40-80 Methylsterol [12] 40-80 Dolichols 1 polyprenols [13] 81 Ubiquinones [14] 10-80 Phospholipids [15] 5-130 Glycolipids [16] 1033-3780 hydrocarbon side chain, was first isolated and structurally elucidated by mass spectroscopy and proton nuclear magnetic resonance spectroscopy [22]. a-Tocomonoenol is normally not reported and its significance is unknown.…”

Phospholipids from palm‐pressed fiber

“…Total phospholipids were determined according to Goh et al (8). Modified Zinzade's reagent (4 mL) was added to a sample of the purified phospholipid fraction and shaken for 30 min.…”
