Oregano essential oil is a natural product that presents antimicrobial and antioxidant properties that can use on the preservation of meat. Thus, the objective of this work was to study the effect of the concentration of oregano essential oil (0.5% and 1%) and storage time (0, 35 and 70 days) at -10 °C, on physicochemical, microbiological and sensory characteristics of guinea pig meat vacuum packed. For this was used guinea pigs of Peru race with 3 months of age-old and weight range between 600 and 700 g. Oregano essent...
