Flour properties are summarised in Table 1. The ash content of defatted flours was lower than the control, which might be caused by the removal of mineral elements when the samples were treated with chloroform to remove lipid from the flours. The colour parameters, L*, a* and b* of defatted flours were higher than those of the control which illustrated that pigments were removed together with lipids by chloroform, resulting in brighter and less yellow flours.
