Food Technol. [online]. 2011, vol.14, n.4, pp. 267-274. ISSN 1981-6723. http://dx.doi.org/10.4260/BJFT2011140400032.
This work aimed at elaborating and evaluating cookies formulated with different concentrations of wheat or rice brans. The cookies were produced substituting 10, 20 and 30% of the wheat flour with rice bran or 15, 30 and 45% of the wheat flour with wheat bran, as well as standard cookies containing no bran. The cookies were evaluated in relation to their physical characteristics (weight, apparent volume, specific volume, diameter, thickness and spread factor), sensory acceptability (color, appearance, flavor, crispiness, softness, chewiness and taste), and purchase attitude. The physical characteristics of the cookies formulated with different brans were similar to the respective standard cookies. As for the sensory attributes, the 20% rice bran cookie presented all the attributes equal or better than the standard cookies, except for chewiness. The cookies elaborated with wheat bran did not differ from each other in four of the seven attributes studied, besides showing a better appearance and color than the standard cookies. The 15% wheat bran cookie was the crispiest. In relation to purchase intention, from 32 to 43% and from 31 to 46% of the panelists would buy the cookies elaborated with wheat bran and rice wheat, respectively. Therefore, the brans studied can be added to cookies (15% of wheat bran and up to 20% of rice bran) without altering their physical and sensory characteristics, with a potential consumer market.
