TECHNOLOGY OF USE IN FOODS: Treatment of flour with chlorine dioxide is normally carried out at the mill. The chlorine dioxide, in the<br />

form of dyox gas (maximum 4% chlorine dioxide) must be generated on site, usually by the reaction of<br />

sodium chlorite solution and chlorine gas in a stream of air. Flour treated with chlorine dioxide is<br />
