Bioactive food packaging is a trend in food packaging science and technology, which is focused on the consumer's health benefits provided by the edible polymeric packaging and the inclusion of bioactive molecules of natural origin, probiotic microorganism and/or prebiotic molecules. Several types of edible films and bioactive molecules have been used in order to create bioactive molecules. In some cases, mechanical and barrier properties of the edible film are enhanced by the bioactive molecule. Likewise, inclusion of probiotics could also lead to enhanced properties of the film. This review will be useful to understand the different components and characteristics of the different types of bioactive films.
Background: Aspergillus niger is one of the most common fungal contaminants of food products, leading to several economic losses on fruit, vegetables and other food products during storage. Over the years, several new techniques have been developed to control fungal growth, including photodynamic inactivation, in which excitation of a photosensitizer in the right wavelength leads to ROS production and microbial death.Results: On this paper, curcumin was used as a natural photosentitizer against A. niger spores. Nanoemulsions were used in order to encapsulated curcumin and increase its water solubility. Results showed that spores inhibition could reach up to 80% after 3 min of irradiation while values for un-encapsulated curcumin were around 30%. Conclusion:Results presented show that nanoemulsions could be use to enhance the photoinactivation properties of curcumin, against fungal spores from A. niger. This type of process can be use for food decontamination and preservation.
En este trabajo se realizó la caracterización del almidón de plátano pompo rayado extraído a través del método húmedo. El material obtenido se caracterizó de acuerdo con sus propiedades fisicoquímicas como contenido de humedad, fibra cruda y relación amilosa/amilopectina y adicionalmente se estudiaron sus propiedades funcionales: índice de Blancura (IB), índice de absorción de agua (IAA), índice de solubilidad en agua (ISA) y el poder de hinchamiento (PH). Los resultados indican que porcentaje de amilosa fue aproximadamente del 30,2 %, porcentaje dentro de encontrado para musáceas, pues, el contenido de amilosa depende del origen botánico. Por su parte, presenta un contenido de fibra alto encontrándose en 6,68%, superior a lo encontrado para otras variedades de plátano, las cuales se encuentran entre 2.5 – 4,0%. El estudio de las propiedades funcionales del material obtenido evidencia un índice de blancura mayor en comparación con las otras musáceas. Los valores para IAA que son aceptados por la FAO oscilan entre 0,82 y 15,52. Sin embargo, para los ISA se encontraron índices bajos cercanos a 0.333. El PH es un parámetro que va de la mano con el IAA en consecuencia, presenta el mismo comportamiento, con lo cual se pudo establecer que el almidón a tratar se encontró dentro de los rangos considerándose de buena calidad.
