Quality of western Canadian mustard 2014

Quality of domestic mustard seed: Yellow

Oil and protein content for yellow mustard is summarized by grade in Table 5. Comparisons to previous years' data are in Figures 5 and 6.

Yellow mustard has characteristically lower oil content and higher protein content than oriental and brown mustard (Table 5). Mean fixed oil content (30.7%) in Yellow Mustard, No. 1 Canada was lower than the mean in 2013 (32.3%). Meanwhile, mean crude protein content (30.9%) was higher than the 2013 mean (29.5%) (Figure 6). Fixed oil content in samples of Yellow Mustard, No. 1 Canada from producers ranged from 25.1 to 34.7% while crude protein ranged from 26.3 to 37.7%.

Fatty acid composition for yellow mustard composites is provided in Table 6. 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 34.3%, compared to 34.7% in 2013. Total saturated fatty acids (5.1%) and iodine values (101 units) were slightly lower than 2013 values.

Chlorophyll content of yellow mustard composites is provided in Table 7. Chlorophyll content in Yellow Mustard, No. 1 Canada was 0.9 milligrams per kilogram (Figure 5), which corresponds to the low distinctly green seed count (% DGR). The lower grades had slightly increased levels of chlorophyll, as high as 4.1 milligrams per kilogram for No. 4 Canada. Chlorophyll content for No. 1 Canada was similar to the 5-year mean of 0.8 milligrams per kilogram.

Distinctly green tolerances are applied to crushed seeds which are a distinct green throughout. Pale green or immature seeds are taken into account in the evaluation of colour. The % DGR results are the averages of the individual samples included in the composite.
