This study aimed to evaluate the postharvest camu-camu by using cooling and modified atmosphere propitiated by the films of polyvinyl chloride (PVC) biaxially oriented polypropylene of 50µm thickness (BOPP50) to evaluate the durability the control (without packaging). The fruits were kept at 5±1°C and 90±2% relative humidity for 25 days and evaluated every four days of storage regarding firmness, pH, soluble solids, titratable acidity, vitamin C, anthocyanins, weight loss and CO2 concentration of the atmosphere inside the package. The BOPP50 film showed not be the best alternative for the conservation of camu-camu, because its low permeability to gases caused the accumulation of CO2 inside the package, allowing the fermentation of fruits after 13 days of refrigerated storage. Characteristics of pH, soluble solids, titrable acidity, vitamin C and anthocyanins were not affected by the types of films used, but through the days of storage. The results showed that the use of PVC film with cooling to postharvest camu-camu, was effective to maintain the firmness and reduction in weight loss by keeping the fruit commercially viable for 21 days, while control coated BOPP50 was unviable with 13 days of storage.
