In this paper, we evaluated the effect of certain oils or fats (corn oil, margarine and beef fat) on the physico-chemical, microbiological characteristics and sensory quality of native chicken and rabbit sausages as low fat sausages. The sausages were evaluated by physicochemical analysis of pH, aw, moisture content, protein and fat, TPC and Salmonella as microbiological characteristics, as well as flavor, juiciness and overall acceptability as sensory quality, and with regards to diversification of meat products in Indonesia. Three formulations for native chicken (FA) and rabbit (FB) sausages were prepared: FA1 and FB1 (with 10% corn oil); FA2 and FB2 (with 10% margarine): FA3 and FB3 (with 10% beef fat). Results indicated no significant difference (p<0.05) between the pH and aw values of native chicken and rabbit sausages using different fat sources. The moisture content was significantly different (p<0.05) both between the native chicken and rabbit sausages and the types of fat source (corn oil, margarine and beef fat) added. No effect on protein content was found both in native chicken and rabbit sausages. The lowest fat content was found in rabbit sausages (18.79 + 0.70%) where corn oil was added as a fat source. Lowest TPC was also observed. Salmonella were not detected in any of the sausage groups. There was no significant difference (p<0.05) in various sensory attributes. In conclusion, native chicken and rabbit meat seems to be a suitable alternative for low fat sausages production, particularly with corn oil as fat source.
