In this study, cytotoxicity of ethanol extract of propolis (EEP) originating from Sivas, Turkey was screened against several cancer cell lines, namely PC-3, U87MG, A-549, mPANC96, CaCo-2, MCF-7, HeLa, MDA-MB-231 and a non-tumor cell line HEK293 by MTT assay. The inhibition levels of inducible nitric oxide synthase (iNOS) were also determined by using RAW 264.7 macrophage cells following lipopolysaccharide (LPS) treatment. EEP exhibited significant cytotoxic nitric oxide inhibition activities with an IC50 value of 0.1 ± 0.1 μg/ml indicating a high potential as an anti-inflammatory agent. In spite of these promising results and the fact that propolis is a highly nutritive substance, its low solubility and bitter taste limit the applications as a natural supplement. Encapsulation might serve as a good strategy in order to overcome these problems. Complex coacervation was applied where the main focus was on surfactant type, polymer ratio (alginate:gelatin), stirring rate and concentration of core material. The mean particle size of unloaded microparticles were 22.62 μm obtained with gelatin:alginate ratio of 1:1 at a stirring rate of 1400 rpm with 2 ml of 1 % (w/v) sodium carboxymethyl cellulose (Na-CMC), whereas addition of EEP at a concentration of 100 mg/ml increased the mean particle size to 36.44 μm and yielded an encapsulation efficiency of 98.77 %. The cytotoxicities of EEP loaded microparticles were also assessed both on MCF-7 and MDA-MB-231 where similar results were achieved as free EEP which can enhance the possible use of propolis extract in the industry as a natural supplement.

“…The use of antimicrobial packaging increases food safety (Rizzolo et al, 2016) and minimize the addition of synthetic additives directly to food (Moradi et al, 2016). Besides, some antimicrobial agents confer unpleasant sensory characteristics to food products and additives incorporation into packaging avoids this issue (da Silva Dannenberg et al, 2016).…”

Biodegradable films based on thermoplastic corn starch (TPS) and copper particles with antimicrobial capacity were developed. Copper nanoparticles (Cu) and silica coated copper microparticles (Si-Cu) in the range of 0.25 to 5 % were used. Composite films were obtained by melt-mixing and subsequent thermo-compression. Particles distribution within TPS matrix and the presence of some pores and cracks, induced by Si-Cu particles, was evaluated by SEM. The presence of both fillers gave composite films a brown pigmentation and decreased their transparency; these effects were more pronounced at higher particles concentrations. Regarding mechanical properties, copper particles at 1 and 5 % acted as reinforcing agents increasing the maximum tensile strength but their presence lead to a decrease in elongation at break, affecting films ductility. Composites inhibited the growth of Gram+ and Gram- bacteria, demonstrating their antimicrobial capacity. Copper effectively migrated to a simulant of aqueous foods and naked particles concentration in the simulant medium resulted higher than the minimum inhibitory concentration for bacteria. The characteristics and properties of developed composite films make them an interesting material for food primary packaging, mainly for meat fresh products.

“…Por otro lado, Rizzolo et al (2016) estudiaron la posibilidad de aplicación de propóleos en jamón cocido almacenado por cuatro días a 4 °C, donde se hizo una comparación entre el jamón envasado en papel activo incorporado con propóleo al 0,4% (API) y el jamón envasado solo en papel activo (APP), obteniéndose que el efecto antioxidante permitía que no exista influencia en las propiedades sensoriales, mientras que el jamón envasado solo en papel activo presentó cambios en su composición química, oxidación lipídica y no lipídica y por ende generó las características sensoriales del jamón cocido. Vargas-Sánchez et al (2015) estudiaron las propiedades de estructura antirradical de flavonoides (crisina, galangina, pinocembrina y pinostrobin) y ácido fenólico (éster de ácido cafeico fenetil) se encuentra comúnmente en propóleo, para lo cual se tuvo en cuenta e mecanismo de inhibición de transferencia H-átomo (HAT), la transferencia de electrones-etapas de transferencia de protones (Splet) y la la transferencia secuencial de la pérdida de protones de electrones (SET-PT).…”

RESUMENLas investigaciones relacionadas con el envasado activo están encaminados hacia la caracterización de nuevas películas basadas en hidrocoloides de fuentes no convencionales y la adición de agentes que proporcionen funcionalidad al envase. A los propóleos se les atribuyen diferentes propiedades biológicas, tales como: antitumorales, antiprotozoarias, antivirales, antioxidantes, antiinflamatorias, antibacteriales y antifúngicas; en particular, se ha encontrado que esta sustancia inhibe el desarrollo de patógenos de poscosecha como Botrytis cinerea y Penicillium expansum. El efecto de la incorporación de propóleo en propiedades funcionales de películas de quitosano, dentro de las propiedades estudiadas se determinó que la adición de propóleo redujo la permeabilidad de vapor de agua en las películas. Por otro lado, la incorporación de propóleo en películas a base de hidroxipropilmetilcelulosa, dieron lugar a una ligera disminución en la densidad y el pH. Respecto a las propiedades mecánicas, las películas de propóleo mostraron mayor alargamiento a la rotura (%) y los valores más bajos de resistencia a la tracción y módulos elásticos. El estudio permitió demostrar el efecto antibacteriano de ambos extractos de propóleo (los extractos etanólicos de propóleo fueron más efectivos que los extractos acuosos), además de que la actividad antibacteriana depende del lugar del que se extrae el propóleo y de la resistencia de estos microorganismos, siendo que las bacterias Gram-positivas son más susceptibles que las bacterias Gram-negativas. Las películas que contienen propóleos mostraron una notable actividad antifúngica contra los hongos ensayados, que fue más intensa frente a A. nigerthan contra Penicillium specie y componentes del propóleo tales como la rutina, quercetina y naringenina fueron los principales compuestos fenólicos del propóleo por lo que a la vez fueron los principales contribuyentes a la actividad antioxidante.Palabras clave: Envase activo, propóleo, propiedades mecánicas, antibacterial, antifúngico, antioxidante. ABSTRACTThe researches related to active packaging are directed towards the characterization of new films based on hydrocolloids from unconventional sources and the addition of agents to provide functionality to the package. A propolis are attributed different biological properties such as: anti-tumor, antiprotozoal, antiviral, antioxidant, antiinflammatory, antibacterial and antifungal; in particular, it has been found that this substance inhibits the development of postharvest pathogens such as Botrytis cinerea and Penicillium expansum. The effect of incorporating propolis into functional properties of chitosan films within the properties studied determined that the addition of propolis reduced the permeability of water vapor in the movies. Otherwise propolis addition in films to hydroxypropyl methylcellulose base, gave in a slight decrease in the density and pH. Regarding the mechanical properties, the films of propolis showed higher elongation at break (%) and the lowest values of tensil...
