Abstract

Texture, or tenderness, may be evaluated by measuring the force necessary to cause rupture of muscle fibers. The aim of this paper was to analyze the texture of muscles fixed and kept in alcohol, throughout a year, by using a texture analyzer. Forty eight poultry breasts were weighted, fixed and kept in a 96º GL ethylic alcohol solution. Analyses were performed at 15, 30, 90, 180 and 360 days of conservation, besides the one of the control group of fresh breasts. Values of shear forces of different groups increased progressively from 3.38 (control group) to 15.31 Kgf (180 days), decreasing to 9.53Kgf after 360 days. It was concluded that when muscles are fixed and kept in ethylic alcohol 96º GL the tenderness is decreased, becoming almost five times harder during the first six months and three times harder after a year. It is suggested that muscle anatomic pieces dissection occurs up to 90 days after fixation and conservation in 96º GL alcohol or around 1 year on this conservation product because there is smaller muscle stiffness in these times. Although the alcohol effect in texture of poultry muscle tissue has being studied in this paper, it is believed that, due this great tissue homogeneity, these data might be taken or being basis to similar studies in other species.
