The Makala from maizecomposite fl our in the present study received an overall acceptabilityscores between 2.8 and 4.2 on a fi ve-point hedonic scale. There<strong>for</strong>e,Makala made from composite fl our containing maize, to a large extent,is satisfactory to the consumers in Northern Cameroon.ConclusionImproved maize cultivars from Cameroon were used to preparecomposite fl ours <strong>for</strong> Makala production and the effects of cultivar andprocessing methods on fl our properties were evaluated. Substitutionlevel affected the product properties more than cultivar differences.
