Yellow mustard has characteristically lower oil content and higher protein content than oriental and brown mustard (Table 2). Mean fixed oil content (32.3%) in Yellow Mustard, No. 1 Canada was higher than the mean in 2012 (29.3%). Meanwhile, mean crude protein content (29.5%) was lower than the 2012 mean (31.9%) (Figure 4). Fixed oil content in samples of Yellow Mustard, No. 1 Canada from producers ranged from 27.7 to 36.1% (Table 2). Crude protein content in samples of Yellow Mustard, No. 1 Canada from producers ranged from 25.2 to 34.7% (Table 2).

Fatty acid composition for yellow mustard composites is provided in Table 3. 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 34.7%, compared to 35.1% in 2012. Total saturated fatty acids (5.1%) and iodine values (103%) were similar to 2012 values.

Chlorophyll content of yellow mustard composites is provided in Table 4. Chlorophyll content in Yellow Mustard, No. 1 Canada was 0.6 milligrams per kilogram (Figure 6), which corresponds to the low distinctly green seed. The lower grades had slightly increased levels of chlorophyll, as high as 1.6 milligrams per kilogram for No. 4 Canada. Chlorophyll content for No. 1 Canada was similar to the 4-year mean of 0.9 milligrams per kilogram.
