This report presents information on the oil, protein and total glucosinolate content and the fatty acid composition of oriental (Brassica juncea), brown (Brassica juncea) and yellow (Sinapis alba) mustard grown in western Canada in 2015. The data was obtained from analyses of harvest samples collected by the Canadian Grain Commission.
Mean fixed oil content for the top grade for oriental mustard in the 2015 harvest was higher than the 10-year average (43.2% versus 42.3%); while for brown and yellow mustard it was lower: brown (37.4% versus 38.8%); yellow (29.5% versus 30.5%) (Figures 2, 3 and 4). Conversely the mean crude protein for the top grade oriental mustard was lower than the 10-year average (25.3 versus 26.2%) while for brown and yellow it was higher: brown (27.7% versus 26.9%), yellow (32.3% versus 31.3%). Total glucosinolate content in the top grade mustard was 127 micromoles for oriental and 112 micromoles per gram for brown, which was higher than the 10-year average of 122 micromoles per gram for oriental and 107 micromoles per gram for brown mustard.
