Effect of Incorporation of Oats and Malted Barley Flours on the Quality of Cookies

The study aimed to determine the potential of oats and malted barley flours incorporation on cookie making. D-optimal mixture design was employed for formulating the recipe of cookies. Seven different formulations of recipe containing oats flour: malted barley flour: wheat flour in the ratio of 20:25:55, 15:30:55, 13:32:55, 10:35:55, 7:38:55, 5:40:55 and 100:0:0 was prepared. The prepared cookies were subjected to sensory evaluation for consumer acceptability and the data obtained were statistically analyzed using two-way ANOVA (no blocking) at a 5% level of significance. From the mean sensory scores, the formulation 10:35:55 was selected as the optimized formulation and subjected to proximate analysis. The optimized cookies were significantly (p<0.05) superior in the case of protein (7.50%), fat (22.93%), fiber (2.90%), and ash content (0.97%) to wheat cookies (6.43%, 18.83% 0.83% and 0.41% respectively) as seen higher in oats and malted barley flours than wheat flour. The calcium content was found to be significantly (p<0.05) higher in optimized cookies (35.3 mg/100g) than wheat cookies (18.40 mg/).
