The aim of this thesis was to determine the effect of three extracts (1, 3 and 5%) of the floral branch of blackberry, Rubus robustus C. Presl, on the count of viable mesophiles, pH, color, texture, and odor of the fillet of turkey breast, Meleagris gallipavo. The lowest mesophil count was obtained with the 5% extract; the increase in the concentration of the extract decreased the pH value of the fillet. The modified Levene test was applied to determine the homogeneity of variances (P > 0,05); then, the analysis of variance to determine the significant effect of the concentration of the extract on the count of mesophiles, pH, color, texture and odor; and finally, the Duncan test to determine the best treatment and Dunnet test to compare each of the treatments with the control. All treatments had a significant effect on viable mesophiles, pH, color, texture, and odor. For color, it was measured in luminosity (L *) and chromaticity (a * and b *); in all treatments the fillets were opaque and dyed green and yellow, unlike the control that conserved its brightness and pinkish color characteristic of the turkey breast. The measurement of the instrumental texture was carried out with the extract at 3%, which indicated greater hardness and lower elasticity in the fillets; whereas, the semitrainned judges determined the greater juiciness in the fillets with the 5% extract. For the sensory evaluation of the odor with treatments, the semitrainned judges indicated that they ““disliked a lot““ in front of the control. The best treatment was attributed to the use of 5% blackberry extract; because it produced the lowest count of viable mesophiles and the lowest pH variability.
