Fatty acids of triglycerides from Citrus juice sacs

Abstract

The fatty acid composition of trigylcerides from oranges, grapefruit, lemons and limes, was determined by GLC. Each species possessed its own intrinsic fatty acid pattern which might be used to differentiate it from the other species. The five major acids in all species were palmitic, palmitoleic, oleic, linoleic and linolenic. Collectively these acids comprised greater than 92% of the total acid content. Lemons were distinguished from all other species by their higher 16/16:1 ratios while grapefruit showed the highest total percentage of 16 and 16:1 acids. Lemons and limes contained higher percentages of branched-chain acids than oranges and grapefruit. © 1974.
