Two approaches were used to explore altematives to chlorination of cake flours. The first was aimed at identifying the flour component (s) responsible for the improving action of chlorine, using separation and reconstitution techniques. The second approach investigated the potential of ozone as a chlorine replacer.
Cake volume was used as the main quality parameter. Chlorinated and unchlorinated flours were separated into three fractions-gluten, starch and solubles, and lipids. The initial aim was to interchange the three fractions between the two flours in order to pinpoint the fraction contributing to the improvement by chlorination. However , on
