Comparative fatty acid composition of linseed oil produced in northern and southern Queensland

Abstract

Oil from 8 oil-seed flax cv. grown in Queensland at Walkamin (lat. 17°S.) and Hermitage (lat. 23°21'S.) was examined for iodine value (Wijs) and fatty-acid composition during 1965. Palmitic, stearic, oleic and linolenic acids were produced in larger percentages by cv. grown at Hermitage, while more linolenic acid was produced by all cv. grown at Walkamin. There was a significant positive correlation (r = + 0.97) between % linolenic acid and iodine value, and a significant negative correlation (r = -0.91) between oleic and linolenic acids.-F.A.S.
