Chicken meat coated with polyphenol-added hydrocolloid films

Se elaboraron películas comestibles (PC) a base de alginato de sodio (AS) disuelto en caldo de pollo (CP) reducido en grasa y sodio. Como aditivo antioxidante, se incorporaron polifenoles (PF) extraídos de cáscaras de manzana Malus domestica (variedad Red Delicious), previamente sometidas a estrés durante 14 días para incrementar su contenido de PF. Las PC se obtuvieron mediante tratamiento térmico y se aplicaron como recubrimiento en bocadillos de pollo triturado. Adicionalmente, se caracterizaron las películas mediante análisis fisicoquímicos y mecánicos para evaluar su estructura y calidad. Finalmente, se realizó una evaluación sensorial de los bocadillos horneados. Este estudio establece las bases para desarrollar alternativas más saludables a la piel de pollo tradicional, reduciendo componentes nocivos como grasas (incluyendo colesterol) y compuestos potencialmente cancerígenos, sin comprometer la intensidad del sabor.

  • Abstract:

    Edible films (CP) were prepared based on sodium alginate (AS) dissolved in chicken broth (CP) reduced in fat and sodium. As an antioxidant additive, polyphenols (PF) extracted from Malus domestica apple peels (Red Delicious variety), previously stressed for 14 days to increase their PF content, were incorporated. The CPs were obtained by heat treatment and applied as coatings on shredded chicken snacks. Additionally, the films were characterized by physicochemical and mechanical analysis to evaluate their structure and quality. Finally, a sensory evaluation of the baked snacks was performed. This study establishes the basis for developing healthier alternatives to traditional chicken skin, reducing harmful components such as fats (including cholesterol) and potentially carcinogenic compounds, without compromising flavor intensity.
