by Adetunji C. O. , Fadiji A.E, and Aboyeji O.O

Abstract:
Edible films and coatings are an environmentally-friendly alternative method to extend the postharvest life of fresh and minimally processed fruits and vegetables.Edible coatings based on chitosan (CH),Aloe veragel (AL)and its combination with Aloe veragel (CHAL), were developed and applied to cucumber, in order to improve its quality and shelf life during storage. Weight loss, changes in soluble solids, ascorbic acid content, firmness, pH and the percentage of fungal infection of uncoated and coated samples were determined throughout ambient storage for period of 7 weeks cucumberstored at ambient temperature of 25oC, 95-98% RH for seven weeks. The above parameters which are related to post- harvest quality loss were however significantly controlled in the cucumber coated in the following order CHAL>AL> CH>Control. The storability of cucumber fruits was extended by seven weeks. It was concluded that used chitosan mixed with Aloe vera gel could be used as a coating for cucumber could serve as an alternative to post-harvest chemical treatments.
