Abstract


Strawberries cv. Dover with approximately 75% of their surface with red color was packaged in disposable polyethylene terephthalate (PET) container and sealed with PVC film of 15mm thick. Strawberries without film serves as control. The fruits were stored at 12°C for ten days and there were determined during storage time the titratable acidity, solid soluble and vitamin C contents, color, respiration rate, texture and weight loss. After 6 days the strawberries packaged without film had decayed while the fruits packaged with PVC film were in conditions of consumption and commercialization. After 10 days all fruits were inappropriate to consumption. Packages with PVC film extended the shelf life of strawberries preserving the color characteristic of the product and vitamin C content, reducing the respiration rate and weight loss, characterizing this packaging as being adequate to this kind of product.
