Characteristics and Fatty Acid Composition of Almond Tegument Oil — Comparison with Almond Kernel Oil

The total crude fat on dry basis of almond tegumet was about 14% by weight. Chemical and physical characteristics of this oil were determined. The content of unsaponifiable matter, 3.75%, was high. The percentage of saturated acids was 10.32%. The high content of essential fatty acids, 40.34% of linoleic and 1.28% of linolenic should be pointed out. Experimental results corresponding to tegument and kernel oils were compared. Gas chromatographic retention indices of fatty acids methyl esters on Carbowax 20-M, DEGS and SE-30 were determined with analitical purposes.
