Mean oil content for the top grade for oriental, brown and yellow mustard in the 2017 harvest was lower than last year and the 10-year average (Figures 2, 3 and 4) at 40.5, 35.9 and 27.1% while the mean protein for the top grade oriental, brown and yellow mustard was higher at 27.5, 29.3 and 34.5%, respectively. Total glucosinolate content in the top grade mustard was 118 micromoles per gram (µmole/g) for oriental and 108 µmole/g for brown, which is similar to the 10-year average of 120 µmole/g for oriental and 107 µmole/g for brown mustard (Figure 5). Oil, protein and glucosinolates are reported on a dry matter basis.
