ABSTRACT: The use of byproducts generated by the food industry is a strategy that can have advantages in economic, technological, nutritional, and environmental terms. The aim of this study was to evaluate the influence of the addition of byproducts of chicken slaughter (skin and abdominal fat) on the quality of fresh sausage stored under freezing. Partial chemical characterization of the byproducts was performed. Three batches of chicken sausage were prepared with skin, abdominal fat, and with skin and abdominal fat added; thereafter were stored for 135 d in freezer. Partial chemical composition, physical characteristics, microbiological quality, and product acceptance were determined. Skin and abdominal fat are rich sources of fat. However, the addition of skin provided to sausage higher protein content, hardness, water retention capacity, and less cooking loss compared to added abdominal fat treatments. In contrast, the addition of abdominal fat provided higher lipid content to the sausages and displaying higher acceptability. The addition of byproducts in fresh sausage manufacture would be a great strategy to increase the chicken sausage value, with physicochemical quality improvement, and without sensory acceptability issues.
