          Abstract

          The application of polyvinyl acetate (PVA) was assessed as a potential protective edible coating in round-type tomato fruit (Lycopersicum esculentum Mill, cv. Gabriela) at the green stage of maturity. Coated and uncoated fruits were stored at ambient (20 °C, 40 % relative humidity, RH) and controlled (21 °C, 60 % RH) conditions during seven and 14 days and the effects on color, luminosity, weight loss, firmness, °Brix, vitamin C and respiration rate were studied. The polymeric coating did not significantly affect brightness, weight loss, and RR; however, environmental conditions at which the fruits were maintained had significant effects. Despite the statistically non-significant effects, our results showed that PVA coating was associated with slight protection of the fruit compared to uncoated fruits. This outcome is encouraging but suggests that more research is needed to consider these facts and control others that might be important in fruit ripening, such as molecular weight of the PVA, uniformity and thickness of PVA application.

          El acetato de polivinilo (PVA) fue estudiado como recubrimiento comestible protector y de alto brillo en tomate bola (Lycopersicum esculentum Mill, cv. Gabriela) en la etapa no madura del fruto. Los frutos cubiertos y no cubiertos se almacenaron en condiciones ambientales (20 °C, 40 % de humedad relativa RH) y en condiciones controladas (21 °C, 60 % RH) durante siete y 14 días y fueron estudiados los efectos en brillo, pérdida de peso, firmeza, °Brix, vitamina C y tasa de respiración. La cubierta polimérica no produjo un efecto significativo, sin embargo, las condiciones ambientales en las cuales se mantuvieron los frutos sí afectaron significativamente la respuesta de los tomates. A pesar de la no significancia estadística, nuestros resultados revelan que la cubierta protege levemente los frutos comparado con frutos no cubiertos. Este resultado es alentador pero indica que se requiere de mayor investigación, pues deben considerarse para estudios posteriores otros factores como el peso molecular del PVA, la uniformidad y el grosor de la cubierta aplicada.
