Evaluación del efecto anitimicrobiano de la reuterina en cubiertas comestibles en fresas

Abstract

Resumen del reporte técnico en inglés Strawberries has a very short shelf life about 3-7 days, due to that spoilage during traspontation is frequent, that result in important economic losses. With the finality of preserve stawberries some strategies has been developed such as the chemical preservatives, however, utilization of chemicals in food has been lose popularity and actually people wants more natural foods, healthy and with extended shelf life. The aim of this proyect was to evaluate shelf life of stawberries with edible films added with reuterin and lemmon oil in comparison with stawberrries without edible films. Futhermore, stawberries were inoculated with spores of an important spoilage microorganism called Penicillium spp. to make possible the evaluation of reuterin efectivity as antimicrobial in 3 edible films. The development of this proyect includes the pectin extraction from orange peel, with a pectin yield of 15.33 %. Edible films with reuterin does not significantly affect quality of the fruit, in contrast, strawberries were observed more attractive. Finally, edible films with reuterin achieve the inhibition of Penicillium spp. growth up to 2 logarithmic cycles in comparison with control, although when spores were present never germinated and extended shelf life of strawberries up to 27 days.
