The fatty acids of menhaden oil

II. The separation of the methyl esters of menhaden oil into saturated, monoethylenic, and polyethylenic fractions by low temperature crystallization. The composition of the saturated and monoethylenic fractions

  • Published:

Summary

The methyl esters of menhaden oil have been separated into three fractions by low temperature crystallization; saturated esters, monoethylenic esters, and polyethylenic esters, the contents of the fractions being roughly 30.9, 15.1 and 54.0%, respectively. The saturated fraction was contaminated with about 5% of the ME esters. The ME fraction, in turn, contained small amounts of methyl myristate and PE esters; further, the recovery of ME esters by the procedure was incomplete.

The saturated and ME fractions were separately distilled, and observations were made on the nature and amounts of the acids in the resulting fractions. The low temperature crystallization technic was shown to be useful in the separation of the complex mixtures of esters found in fish oils.
