Potato manufacturers demand just the right hue of golden brown for their customers, whether the processing is frying or baking. A consumer will see some intentional colour variation instead of a uniform, bland appearance. Different processed potato products require different colour solubility solutions.
Regulatory guidelines have a significant impact on which potato colouring is selected. French fry manufacturers have multiple tools to achieve a yellow to brown hue, depending on the country and the process. DDW formulates naturally coloured potato chips by adding colouring to the structure — not just the surface.
