The aim of this study was to obtain hydroethanolic extract of propolis by extraction, assisted by focused microwave, and to apply it in Tuscan-style sausage. The extract was used at concentrations of 0.5%, 1.0% and 2.0% (w/v) in the manufacture of the sausage, which was then analyzed in cold storage at 4 °C for 56 days. The following analyses were performed: mesophilic and psychotrophic organisms; coliforms at 35 and 45 °C; positive and negative-coagulase Staphylococcus, sulfite-reducing Clostridium, and Salmonella spp. The results were below the limits established by the Brazilian legislation, with some changes at the end of the study. Consequently, propolis extract prolonged the shelf life of the Tuscan-style sausage for 56 days and it is therefore an ingredient that can be potentially used in the preparation of this product.Keywords: sausage; propolis; extraction.Practical Application: The propolis extract provided microbiological stability to the sausage.

Mayonnaise is one of the most consumed sauces in the world and beans have great technological functional properties. As a result, beans can be used in the production of mayonnaise as a partial substitute for egg yolk (EY), reducing cholesterol content, post-harvest losses and adding nutritional value to mayonnaise. This study evaluated the effect of the partial replacement of EY by landrace common bean flour (LCBF) on the parameters of rheology, chemical and physical composition of mayonnaise. Four mayonnaise formulations were developed: T1 (Standard), 100% egg yolk (EY); T2, 75% EY and 25% FFC; T3, 50% EY and 50% LCBF; T4, 25% EY and 75% LCBF. The partial substitution of EY for LCBF increased the protein content, decreased the content of lipids and cholesterol. The obtained mayonnaise continued to exhibit pseudoplastic behaviour, being a characteristic of non-Newtonian fluid. The water activity of the mayonnaise was not changed with the replacement of the partial of the egg yolk and the pH decreased during the storage. The substitution of EY can be carried out in quantities of up to 50% without prejudice to mayonnaise, the formulation with 50% substitution presented the best viscosity and remained stable, similar to the standard mayonnaise.
