The higher the yellow intensity of mustard, the higher the amount of turmeric needed. Mustard formulated with turmeric requires proper packaging to compensate for its light sensitivity. Some mustard contains beta-carotene to provide yellow to orange hues. Brown mustard often contains Class III or Class IV caramel colour for acid stability.
