Oils from improved high stearic acid sunflower seeds.
J Agric Food Chem. 2005 Jun 29; 53(13):5326-30.JA

Abstract

Seed oils from new recombinant high-stearic sunflower lines (Helianthus annuus L.) have been characterized. These new lines were generated by crossing high stearic acid lines between themselves or by crossing them with standard and high-oleic sunflower lines. Of the novel lines generated, the lines CAS-29 and CAS-30 are on a standard background and contain up to 34.5% of stearic acid. In contrast, CAS-15 and CAS-33 are on a high oleic acid background and contain only 24.9 and 17.4% of stearic acid, respectively. The stearic acid contents of lines CAS-19 and CAS-20 are 10.0 and 21.5%, respectively, and they have only one of the two genes that control the high stearic acid trait. In accordance with their vegetable origin, these lines have a low percentage of stearic acid in the sn-2 position of the TAGs, from 0.6 to 2.1%. The amount of disaturated TAGs increases with the stearic acid content, from 1.8% in the standard line to between 5.1% in CAS-20 and 38.5% in CAS-29. There was also a concomitant reduction in triunsaturated TAGs, which were reduced to levels as low as 8.4% in CAS-29, as opposed to the 67.9% that they constitute in the standard line RHA-274. The asymmetrical distribution of the saturated fatty acids between the sn-1 and sn-3 TAG positions ranges from 0.26 to 0.36, being lower in those lines with higher oleic acid content.
