Evaluación de films activos de quitosano enriquecidos con Bidens andicola y Rosmarinus officinalis como envase primario para carne fresca de pollo.

Abstract

The objective of this study was to assess the capacity of the conservation of chicken samples treated with Chitosan active films enriched with hydroalcoholic extract of Bidens andicola and essential oil of Rosmarinus officinalis (Romero) in different concentrations and to value which treatment holds the best characteristics to extend the usage time of the chicken. For the experimental design, a factorisal of 3 x 3 was used, in which every film was claborated with varying concentrations of hydro alcoholic extracts of Bidens andicola (0%, 1%, and 2%) and essential oil of Rosmarinus officianalis (0%, 1%, and 2%). To study these films microbiological tests were performed for the recount of total coliforms and mesophilic acrobes based on the 3M Company Petri Film plate counting method, in addition to Salmonella detection tests. PH measurements, color parameters, and sensory analysis were also performed during days 0, 3, 6, 10 of refrigerated storage at 4 degrees Celsius plus-minus 2 degrees Celsius, being the treatment of concentrations of Bidens andicola 0% and Rosmarinus officinalis 2 % the best package to increase the shelf life of the chicken, it was also determined that the chicken without packaging until the third day of storage in refrigeration had the quality characteristics as established in the NTE INEN2346 technical standard norm.
