BIOPRESERVATION POTENTIALS OF NON-FOOD PLANTS ON SOME EDIBLE FRUITS IN DELTA STATE, NIGERIA

Abstract

The study was carried out to investigate the biopreservation potentials of some non-food plants on some edible fruits in Delta State, Nigeria. Non-food plants such as Emilia sonchifolia, Tridax procumbens and Jatropha curcas were sourced from different
locations in Delta State, Nigeria and the plant materials were extracted. Edible fruits purchased from different locations in Delta State, Nigeria were subjected to preservation using extracts from non-food plant materials. The visual observation using sign of change in colouration, spoilage and rot showed that visibility of rot was observed in the control (0.0) nine days after storage with total rot occurring at day fifteen. 25% concentration treated fruits showed sign of rot at day twelve with complete rot at day fifteen while both 50% and 75% concentrations recorded rot signs 15 days after storage with complete rot at day 18. The extracts coated with 100% treatment concentration recorded rot and spoilage at day 18. One hundred (100%) treatment was more effective compared to other treatment concentrations in the preservation of shelf-life of I. gabonensis. With extract of active components, some refinement, Jatropha curcas may be considered, as a source of medicament in the control of fungal diseases in edible fruits
