Efecto de las películas sobre la vida útil de frutas frescas empacadas

Abstract

Abstract: This project evaluated the shelf life of three short-life fruits: strawberries, cherry tomatoes, and tree tomatoes, using three types of packaging: cling film, nylon packaging, and commercial polypropylene bags. Fruits purchased from shopping centers without prior storage were disinfected, dried, packaged, and stored in a refrigerated container at 4°C. Triplicate analyses of pH, °Brix, acidity, color, and texture were performed in five measurements. The results highlighted °Brix and texture as the parameters with the most significant changes, becoming determining factors for the shelf life of the fruits studied. In the case of strawberries and tree tomatoes, texture was the key indicator, while in cherry tomatoes, Brix degrees were the most important. For strawberries and cherry tomatoes, nylon packaging proved to be the most effective, extending shelf life up to 15 and 14 days, respectively. On the other hand, for tree tomatoes, polypropylene packaging proved to be the most effective in preserving texture, lasting up to 18 days.
