Quality Evaluation of Strawberries Packed with Perforated Film

Strawberries were stored in perforated film packages with different number and diameter of perforation for 5 days at 18°C simulating the ordinary logistics in Hefei. The non-perforated film packages were used as the control. Several quality parameters of strawberries were determined and analyzed everyday during storage. The principal component analysis was applied to the comprehensive assessment of strawberry quality. The results showed that suitable diameter and number of perforation could maintain strawberry quality. The comprehensive quality of strawberries packed in perforated film with 36 perforations of diameter 0.5mm was the best, followed by the ones packed in non-perforated film with internal atmosphere of low oxygen and high carbon dioxide concentration.
