The sensory evaluation and processing qualities of cooked maize paste (pap) and cooked cowpea paste(moinmoin) products from treated maize and cowpea grains stored with essential oils of three plant spices (Eugenia aromatica, Piper guineesis and Monodora myristica),were investigated. Essential oils were applied at dosage rate of 0, 5, 10, 15 and 20 ml/kg of stored grains for six months. The products were processed, cooked and evaluated for processing and sensory qualities to access the spices and concentration effects of the essential oils extracted with n-hexane. A 9- point hedonic scale was used to evaluate the sensory parameters of taste, aroma and appearance ranging from dislike extremely to like extremely. Panelists were administered well-structured questionnaires to assess the effect of the essential oils, from spices concentration and interaction between spice and concentration on the parameters assessed on the grains. Sensory evaluation data were subjected to 3x5 factorial arrangements. Pap from maize and moinmoin (cooked cowpea paste) from cowpea grains stored with dosage rate of 5 -10 ml/kg grains, were significantly accepted and preferred by the panelists. Nutmeg spiced products at 5 ml/kg for the grains products was ranked highest among other spices.
