Abstract

DIAS, Argélia Maria Araújo et al. Inclusion of coarse wheat bran in the diet and its effect on physical and sensorial properties of goat meat. Ciênc. Tecnol. Aliment. [online]. 2008, vol.28, n.3, pp.527-533. ISSN 0101-2061.  http://dx.doi.org/10.1590/S0101-20612008000300004.

The effect of inclusion levels of Coarse Wheat Bran (CWB) (0; 8.9; 19.8 and 31.7%) in the animal diet on sensorial attributes (goat aroma, strange aroma, color, texture, tenderness, goat flavor, juiciness and general appearance) and physical-chemical characteristics (pH, losses during cooking and color of the meat operating in the CIE (L*, a* e b*) system of goat loins were evaluated. A statistical design of four treatments and four replications was used. The inclusion of CWB did not significantly affect goat meat aroma. However, there was a quadratic effect on color and on the characteristic taste of the meat. Texture, tenderness and general appearance decreased linearly. For pH, the behavior was quadratic, with a maximum of 18.53% and the average percentage of losses during cooking was 25.5%. There was a decreasing linear effect on brightness (L*), which varied from 30.2 to 32.2; red color (a*) was intensified with the increase of CWB levels, and varied from 7.56 to 8.47, while yellow color (b*) showed a quadratic behavior (maximum of 14.53%). The increasing inclusion of CWB in the animal diet affected all sensorial attributes, except for aroma. According to the chromatic evaluation, goat meat color was darker with increasing CWB levels.

Keywords : by-products; tenderness; taste; texture.
