The fatty acids and glycerides of an indian sesame oil

The component acids and glycerides in sesame oil (iodine value 114.1) extracted from seed grown in Eastern India have been investigated. The acids included palmitic 9.4, stearic 5.7, arachidic 1.2, oleic 35.0 and linoleic 48.4% (wt.). The glycerides follow the usual seed‐fat distribution: the chief members present are oleodilinoleins (40%), saturated‐oleo‐linoleins (37%) and dioleolinoleins (15%). 43% of the glycerides contain two linoleic groups and 53% contain one linoleic group per triglyceride molecule. The glyceride structure of groundnut, cottonseed, sesame, sunflower seed and soya‐bean oils are compared, with special reference to their respective dilinoleo‐ and monolinoleo‐glycerides.
