Abstract: To enhance the cool storage effects by package with proper film, fruits of Pumelo (Citrus grandis (L.) Osbeck.cv.Miyou) were individually packed with micro-perforation film and common PE (polyethylene) films with different thickness, and stored at 5–6℃ for 4 months and then 15-days shelf-life at room temperature. O2 and CO2 composition in headspace of different bags were checked, and fruit weight loss, content of chemical quality attributes (total soluble solid, titratable acid and vitamin C), firmness and ethanol content of flesh were measured. There were higher O2 and lower CO2 content in headspace of packaging with micro perforations film. During the experimental period, pumelo packed with micro perforations film were characterized with highest weight losses, but contained highest chemical quality attributes, lowest firmness of flesh, the least ethanol content, and enjoyed best flavor among all treatments. After 15-day shelf-life, the weight losses and ethanol content of fruit in all treatment increased sharply, meanwhile the TSS and TA decreased rapidly. Packaging with micro-perforation film is a good choice to keep better storage and shelf-life quality of pumelo.
