Fatty acid composition of oriental and brown mustard composites is provided in Table 3. Erucic acid (C22:1) levels for Oriental Mustard, No.1 Canada (22.6%) and Brown Mustard, No.1 Canada (23.9%) were similar to the 2016 values of 21.9% and 23.8% respectively. These values for oriental and brown mustard are typical of Brassica juncea condiment mustards.

Total saturated fatty acids for Oriental and Brown Mustard, No.1 Canada composites were 6.1 and 5.9% which was similar to last year’s values for both types at 6.0 and 5.9%, respectively. There were slight changes in the levels of oleic, linoleic and linolenic acid, as a result, the iodine value (an indicator of oil unsaturation) was slightly lower than the 2016 values for both oriental and brown mustard at 116 and 119 units, respectively.

Chlorophyll content of Oriental and Brown mustard composites is provided in Table 4. Chlorophyll content was 1.2 and 1.7 mg/kg for Oriental and Brown Mustard, No. 1 Canada, respectively (Figure 6) which is significantly lower than the 8-year average of 2.0 and 3.8 mg/kg, respectively. Low chlorophyll is an indicator of well matured seeds. The lower grades in both types had higher levels of chlorophyll.
