The colour of flour streams as related to ash and pigment contents
1993
Abstract The behaviours of four white spring wheats on an experimental mill were investigated in terms of how perceived colour was related to the ash and yellow pigment contents of the flour streams. Objective measurements of the perceived colours of streams were obtained in terms of CIELAB colour space parameters. Although particle size differences influenced results, the differences in the CIELAB colour space parameters were related to flour ash contents and flour yellow pigment contents. L * was correlated with flour ash content, b * with flour yellow pigment content and flour colour index ( L * - b * ) with both ash and yellow pigment.
