Summary

The mean oil content for the top grade for oriental, brown and yellow mustard in the 2020 harvest was lower than the 10-year average (Figures 2, 3, and 4) at 40.0%, 35.5%, and 27.6%, respectively. In contrast, the mean protein for the top grade oriental (27.6%), brown (29.3%), and yellow (33.1%) mustard was higher. Total glucosinolate content in the top grade mustard was 126 micromoles per gram (µmole/g) for oriental and 107 µmole/g for brown, which is higher than the 10-year average of 117 µmole/g (oriental) and 105 µmole/g (brown; Figure 5). Oil, protein and glucosinolates are reported here on a dry matter basis.
