Abstract : Two polymeric films were used with and without perforations for the individual packaging of mangoes and apples for short-term storage at an ambient air temperature of 21-24°C. The films used were Nylon/EVOH/PE (Cryovac) and Nylon/PE (E50), a high and a low barrier to oxygen, respectively. Perforation of the bags was necessary due to the products' high respiration rates, which would lead to bursting of sealed bags. The storage quality of apples stored in perforated E50 film bags was higher than those packaged in the Cryovac bags, with a storage life of approx. 1?month. Mature-yellow mangoes packaged in perforated Cryovac bags were found to be of a higher quality than those in E50 bags; storage was limited to 10?d. In all cases, packaging improved the quality of the product when compared to unpackaged product.
