The present research had the purpose of investigating the percentages of fats and cholesterol on chicken sausages processed under the form "light" and "traditional", when submitted to conditions of stockpiling of cooling and freezing. In the elaboration of sausages was used white and dark chicken meat and skin, added of natural, commercial antioxidant seasonings and ascorbic acid. Six treatments and twelve formulations were developed, and six formulations were of "traditional" sausages and six of "light" sausages. The treatment number 1 consisted of products without antioxidant addition, denominated control; the treatment number 2 was formulated with 0.25% of ascorbic acid as antioxidant; treatments numbers 3, 4 and 5 were formulated with commercial antioxidants, in a concentration recommended by the manufacturers' specifications; and finally the treatment number 6 that it consisted of same formulation of the treatment number 5 added with liquid smoking. The sausages were stocked to the temperature of cooling (5-10°C) for 22 days, and freezing (-20°C) for 90 days. Concentrations of fats and cholesterol were determined in the raw material (chicken meat and skin) and in the stored sausages. The results showed that the cholesterol percentages varied in function of the formulation of the sausages "traditional" and "light", presenting these, in relation to the "traditional", a significant reduction of these components. The refrigerated stockpiling and frozen treatment influenced significantly (P <0,05) the concentration of cholesterol in the sausages "light". The effective action of the commercial antioxidants used in the treatments 5 and 6 was clearly observed, where there was not significant variation of the cholesterol tenor along the period of refrigerated stockpiling and/or frozen.
