Low Erucic Acid

Brassica junceais a crucial cultivated mustard species and principal oilseed crop of India and Madhya Pradesh, grown for diverse vegetables, condiments, and oilseeds. Somaclonal variation was explored as a probable source of additional variability for the manipulation of fatty acids, especially low erucic acid contents that may be valuable for this commercially important plant species. The plantlets regenerated from tissue cultures (R0), their R1 generation and respective parental lines were compared for morpho-physiological traits and fatty acid profile for the probable existence of somaclonal variations. The first putative somaclone derived from genotype CS54 contained 5.48% and 5.52% erucic acid in R0 and R1 regenerants, respectively, compared to the mother plant (41.36%). In comparison, the second somaclone acquired from PM30 exhibited a complete absence of erucic acid corresponding to its mother plant (1.07%). These putative somaclones present a source of variation for exploitation in the development of future mustard crops with low erucic acid content.

Liquid Chromatographic

Abstract A rapid gas-liquid chromatographic (GLC) procedure was developed for the determination of C22 fatty acids (mostly erucic acid) in rapeseeds containing less than 5% erucic acid. The method involves an oil extraction from a representative sample of rapeseeds, a vigorous boron trifluoride-methanol transesterification of the oil to methyl esters, and analysis by GLC with the aid of an electronic integrator. Six laboratories participated in a monthly check sample program. By adjusting the GLC detector response with 2 synthetic reference standard mixtures containing 1.0 and 3.0% methyl behenate, interlaboratory agreement within 0.3% C22 was consistently obtained.

The effects of including 5 or 15% of high (regular) and low (Span) erucic acid rapeseed oils or soybean oil on productive performance, total lipid and fatty acid content of egg yolk, and distribution of fatty acids in egg yolk fat were studied. Feed intake varied according to the dietary energy content. However, 15% high erucic acid rapeseed oil decreased feed intake and egg production in comparison with 15% low erucic acid rapeseed oil or soybean oil. Hens receiving rations containing soybean oil produced larger eggs in the treatment than in the pre-treatment period. Five percent regular rapeseed oil in the diet led to a small increase in egg weight, whereas inclusion of 15% regular rapeseed oil in the diet led to a decrease in egg weight. Diets containing the Span oil gave intermediate results. Although the total lipid and total fatty acid content in egg yolk remained constant, the fatty acid composition changed significantly with the experimental diets. The concentration of saturated fatty acids in eggs produced by hens fed diets containing the regular rapeseed oil or low erucic acid rapeseed oil (Span oil) decreased only to a small extent and not in proportion to the amount of these fatty acids present in the diets; but the oleic acid concentration in eggs produced by the hens fed diets containing the rapeseed oil was high. Only 0.2% of erucic acid was found in eggs when 15% regular rapeseed oil was fed to laying hens. The laying hen seems to be able to maintain the level of saturated and monounsaturated fatty acids in yolk lipids in a physiological range. The results indicate that in the laying hen, a partial degradation of erucic acid to gadoleic acid and oleic acid takes place.
