A study was conducted on properties of Anchote (Coccinia abyssinica (Lam.)) flour and its application for cookie production by blending with wheat flour. The experiment was planned with two factors; Anchote blending ratios and baking temperatures. It consisted of nine combinations of treatments executed in a completely randomized design (CRD). The Anchote blending ratios were 10, 15 and 20% and the baking temperatures were 160,180 and 200°C. The functional properties such as water absorption, oil absorption, swelling power, solubility and dispersibility of Anchote flour were 2.44 g/g, 1.92 mL/g, 11.48%, 41.53% and 67.33% while those of the wheat flour was 1.84, 2.18, 9.08, 35.87 and 73.66, respectively with the relevant units indicated. Increasing the blending ratio of Anchote significantly (p<0.05) affected the functional properties of the composite flours. The physical properties of cookies of the composite flours such as spread ratio (6.87 to 10.07), specific volume (1.6 to 1.88 cm³/g) and hardness (6.37 to 17.54 N) were significantly (p<0.05) affected by the blending ratio and baking temperatures. Sensory acceptability data of cookies showed that increasing the blending ratio resulted in reduced scores of all attributes. However, all the scores were above 5.00 on the 7-point hedonic scale indicating positive acceptance. With regard to baking temperature the highest score for each attribute was scored for cookies baked at 180°C. Thus, it can be concluded that Anchote flour can be blended with wheat flour up to 20% to produce cookies of good physical and sensorial acceptable quality.
