Winter camelina seeds as a raw material for the production of erucic acid-free oil

Abstract

Camelina oil is increasingly popular as consumption as oil. Erucic acid is an unwanted fatty acid in oil. First studies on several genotypes have shown that this oil contains varying amounts of eriuc acid. The aim of the study was to analyses content of eriuc acid in all genotypes camelina. Hypothesis was that the content of erucic acid in winter forms is lower than in spring ones. A field experiment with 65 spring genotypes and 9 winter genotypes of camelina was conducted in Poland from 2016 to 2018. The analyses based on two chromatographic methods, i.e. UPLC-DAD and GC-MS, showed no differences in the results for the camelina samples. The average percentage content of the erucic acid in the spring genotypes was 3.432%, and in the winter genotypes was 0.1%. Our three-year research shows that some winter varieties can be used as low erucic acid forms.
