Nanocomposite film can be used to prolong the shelf-life of fruits and vegetables. This research was undertaken to investigate the effects of packaging period and temperature on the quality and self-lives of cucumber and garden-eggs packaged using cassava starch-zinc nanocomposite film. Hundred grams each of cucumber and garden-eggs were wrapped in a 200× 350 mm size nanocomposite film and low density polyethylene (LDPE) of 2.240± 1.076 × 10-10 gm-1Pa-1s-1 water vapor and 1.568± 0.084× 10-10 gm-1Pa-1s-1 oxygen gas permeability. The products were stored at 10−27oC temperatures and 0−9 day periods, and their quality attributes including β-carotene and ascorbic acid were determined. The results showed a high positive correlation for β-carotene and ascorbic acid contents of the cucumber and the garden eggs packaged in the nanocomposite film and the LDPE (p< 0.05). Also, the percentage increase in shelf-life of the packaged products in the cassava starch-zinc nanocomposite films was higher than those packaged in the LDPE materials. This indicates a small quality loss in the products packaged using the nanocomposite film compared with that packaged using the conventional LDPE. Hence, cassava starch-zinc nanocomposite film can be used to extend the shelf-life of the products.
