Strawberries packaged with Polyvinyl Chloride (PVC) film

摘要

Strawberries cv. Dover with approximately 75% of their surface with red colour was packed in disposable polyethylene terephthalate (PET) container and sealed with PVC film of 15 mm thick. Strawberries without film were used as control. The fruits were stored at 12 degrees C for ten days. The following were determined during storage: titratable acidity, solid soluble and vitamin C [ascorbic acid] contents, colour, respiration rate, texture and weight loss. After 6 days, the strawberries packed without film showed decay while the fruits packed with PVC film were in good condition for consumption and commercialization. After 10 days, all fruits were inappropriate for consumption. Packaging with PVC film extended the shelf life of strawberries, preserving the colour 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..
