Candéo,Manuella; Canteri,Maria Helene G; Macedo,Dayana Carla de; Kubaski,Evaldo T; Tebcherani,Sergio M.
ABSTRACT Plastic packaging from petroleum derives used in the food industry represents serious environmental problems. Alternative solutions to these problems consist of the development of biodegradable packaging, such as films and edible coatings including the polyvinyl alcohol (PVA). In this research we evaluated the effect of the PVA application by two different techniques aiming to increase shelf life of ripe tomatoes, cultivar Carmen. The methodology of this study consisted in covering tomatoes with a PVA solution and also with PVA impregnated tracing paper. The different fruit lots were kept in polystyrene trays for 19 days on a laboratory bench at a controlled temperature of 25±3ºC. The fruit analyzes were compared to the control fruits without any...

Effect of calcium chloride and refrigeration on the quality and organoleptic characteristics of cape gooseberry (Physalis peruviana L.) Acta Agron. (Palmira)
Reyes-Medina,Andrea Johana; Pinzón,Elberth Hernando; Álvarez-Herrera,Javier Giovanni.
Abstract The gooseberry is one of the exotic fruit species most important in Colombia. Calcium has been shown to be important for quality maintenance in fruits and vegetables, as it prevents a number of physiological disorders reinforce the cell walls and stabilize cellular membranes. With the aim to increase the fruit calcium concentration, a completely randomized design with four treatments was performed: a control and three applications of CaCl2 (0.5%, 1% and 2%), with four replicates, for a total of 16 experimental units (EU). The fruit was collected at maturity stage 6 according to the standard Icontec NTC 4580, completely healthy and homogeneous. The fruit was subsequently stored at 21 ± 1 ° C (RH 45%). The application of calcium in the gooseberry...
