Quality of western Canadian mustard 2016 - Quality of domestic mustard seed: Yellow

Quality of domestic mustard seed: Yellow

Oil and protein content for yellow mustard is summarized by grade in Table 2. Comparisons to previous years’ data are in Figures 4 and 6.

Yellow mustard has characteristically lower oil content and higher protein content than oriental and brown mustard (Table 2). Mean fixed oil content (30.4%) in Yellow Mustard, No. 1 Canada was higher than the mean in 2015 (29.5%). Meanwhile, mean crude protein content (30.5%) was lower than the 2015 mean (32.3%) (Figure 4). Fixed oil content in samples of Yellow Mustard, No. 1 Canada from producers ranged from 25.9 to 34.4% while crude protein ranged from 26.3 to 37.6%.

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 33.9%, compared to 34.8% in 2015. Total saturated fatty acids (5.2%) and iodine values (102 units) were similar to the 2015 values.

Chlorophyll content of yellow mustard composites is provided in Table 4. Chlorophyll content in Yellow Mustard, No. 1 Canada was 1.2 mg/kg (Figure 6), which corresponds to the low distinctly green seed count (%DGR). The lower grades had slightly increased levels of chlorophyll, as high as 3.1 mg/kg for Sample grade. Chlorophyll content for No. 1 Canada was slightly higher than the 7-year mean of 0.8 mg/kg.
