Vacuum packaged guinea pig (Cavia porcellus) meat, even though is already commercialized, does not have enough information on their technological properties and the effect of vacuum packaging on them. The aim of this study was to determine the behavior of these properties in vacuum packed guinea pig meat at different storage times and evaluate any effect. Guinea pigs were slaughtered at 90 days old (commercial age), previously stunned by electro narcosis, then bled, scalded, depilated, eviscerated, chilled and stored at 2° to 4° C. Hind legs of 90 guinea pigs were used for analysis, samples were taken of the muscles and studied the variables described below: Biceps femoris (water holding capacity and color), Gracilis (pH) and Rectus femoris (tenderness). The day after slaughter, a hind leg was evaluated and its pair was vacuum packaged for evaluation on the treatment assigned (7, 14, 21- or 28-days post slaughter). Vacuum packaged guinea pig meat showed a significant increase in pH, but acceptable, with an initial pH of 5.99 and a final of 6.22. Water holding capacity did not change over time. Whereas, tenderness improved significantly between days 14 to 21. Vacuum packaging served to avoid guinea pig meat discoloration, L* remained constant but a* and b* increased significantly. The best results were found between day 14 and 21 post slaughter. Vacuum packaging does have an influence on guinea pig meat.
