Abstract
The present study evaluated chemical composition, water activity, instrumental color (L∗, a∗, and b∗) and TBARs values of fresh pork sausage prepared with fruit aqueous extract of the Brazilian pepper tree (AESt). Four formulations were prepared: a control formulation with sodium erythorbate (T1), and three formulations without sodium erythorbate and with 0.25% AESt (T2), 0.5% AESt (T3), and 1.0% AESt (T4). Values of color differed significantly (p < 0.05) from the others throughout the experimental time, when T1 and T2 had the lowest and highest L∗ and a∗, respectively. Also, T4 had the lowest b∗ averages and the best stability score, with the least variation. The treatment with 1% of AESt (T4), presented the best results in retarding lipid oxidation, which causes a longer shelf life to fresh sausage.
