Lipid (oil and fat) is one of the basic and important components used in the production of cookies. It plays several roles in their composition and a judicious choice of this ingredient makes it possible to have cheap, delicious and very nutritious cookies. This study aimed to evaluate the effect of refined cottonseeds oil (RCO), refined palm oil (RPO) and red (or crude) palm oil (CPO) on sorghum (Sorghum bicolour var. Gampela) cookies. Oils were incorporated at levels of 16%, 20% and 24%. Cookies quality were evaluated based on quantitative sensory profile, sensory acceptability, preference classification and paired-comparison test. The results of sensory profile tests showed that the sensory descriptors ranged from very low to medium intensity (1.33 to 3.83 on a scale of 5). Both acceptability and classification tests showed that cookies produced with 20% of refined oil (RCO and RPO) and those with 16% of CPO were the most preferred and RCO and RPO with 20% of the oil were appreciated as control cookies produced with 20% of margarine. The colour, texture and fat impression had most influenced the consumers’ preferences. RCO, RPO and CPO exhibit the potential to be used as substitutes to margarine to produce sorghum cookies.
