dc.description.abstractThis study was conducted to examine effects of chitosan (1 % or 1.5%), cinnamic acid (lmM or 5mM) or a combination of chitosan (1.5%) and cinnamic acid (5mM) on shelf life of tomato fruits (Lycopersicon esculentum) stored at ambient temperature (28 °c) for 12 days. The effectiveness of the treatments in extending fruit shelf-life was evaluated by determining overall postharvest quality and postharvest disease of fruits. Coated fruits had a greater visual acceptability than those of untreated fruits. However, coated fruits had no effect in weight loss, total soluble solid content, and fruits firmness. The chitosan coating delayed ripening and the progress of fruit decay due to senescence. Tomato coated with 1.5% chitosan delayed the senescence associated with external colour changes. No sign of fungal decay was observed during the storage period for fruit coated with 5mM cinnamic acid or 1.5% chitosan + 5mM cinnamic acid. By contrast, approximately 9% of tomato fruits coated with 1.5% chitosan without cinnamic acid were infected after six days of storage. The addition of cinnamic acid to the chitosan coating (combined treatment) had a strong inhibitory effect against pathogenic microorganism and decay caused by fungi, thus maintaining the quality attribute and extending the storage life of tomato fruits.en_US
