Background: Tissue texture, or tenderness, may be checked-out by analyzing the force necessary to cause muscle fibers rupture (shearing force) and the result is expressed in kilogram-force (kgf). The aim of this paper was to analyze the texture of broiler chicken breast muscles fi xed in a 10% formaldehyde solution and kept in a 0.5% sodium benzoate and 0.5% acetic acid solution up to 180 days so any alteration regarding resistance and the best moment for dissection could be described.Materials, Methods & Results: Forty chicken breasts were used and muscle texture was analyzed by the shearing force whose values were correspondent to the maximum force necessary to chisel the samples. Eight of 40 breasts were taken as a control group (fresh muscles). The remaining breast muscles were fi xed in a 4% formaldehyde solution and kept in plastic containers with this solution during seven days and, then, eight breasts went through texture analysis. The 24 remaining breasts were set in plastic containers with 0.5% sodium benzoate and 0.5% acetic acid solution. The texture analyses were taken out at 30, 90 and 180 days of conservation, and eight breasts were used in each time. The shearing force was
