Quality of western Canadian mustard 2015

Quality of domestic mustard seed: Yellow

Yellow mustard has characteristically lower oil content and higher protein content than oriental and brown mustard. Mean fixed oil content (29.5%) in Yellow Mustard, No. 1 Canada was lower than the mean in 2014 (30.7%). Meanwhile, mean crude protein content (32.3%) was higher than the 2014 mean (30.9%). Fixed oil content in samples of Yellow Mustard, No. 1 Canada from producers ranged from 23.9 to 34.9% while crude protein ranged from 25.6 to 37.2%.

The fixed oil in yellow mustard contained higher amounts of oleic (C18:1) and erucic acid (C22:1) but lower amounts of linoleic (C18:2) and linolenic acid (C18:3), compared to the oil in oriental and brown mustard. Mean erucic acid content in Yellow Mustard, No.1 Canada was 34.8%, compared to 34.3% in 2014. Total saturated fatty acids (5.2%) and iodine values (103 units) were slightly higher than 2014 values.

Chlorophyll content in Yellow Mustard, No. 1 Canada was 0.8 milligrams per kilogram, which corresponds to the low distinctly green seed count (% DGR). The lower grades had slightly increased levels of chlorophyll, as high as 3.6 milligrams per kilogram for Sample grade. Chlorophyll content for No. 1 Canada was the same as the 6-year mean of 0.8 milligrams per kilogram.
