Abstract

This study aimed to investigate the effects of synthesized silver nanoparticles (AgNPs), Azadirachta indica (neem), and Moringa oleifera (moringa) leaf extracts on the shelf life and quality retention of tomato (Solanum lycopersicum L.) fruits during storage. Thirty-five (35) red, matured tomato fruits were collected, rinsed and grouped for each treatment with AgNPs, neem and moringa coating: Control (n=5), moringa aqueous leaf extract (MALE) (n=5), neem aqueous leaf extract (NALE) (n=5), 1:9 and 6:4 moringa aqueous leaf extract synthesized silver nanoparticles (MALE-AgNPs) (n=5), 1:9 and 6:4 neem aqueous leaf extract synthesized silver nanoparticles (NALE-AgNPs) (n=5), respectively. The firmness, shelf life, and postharvest decay percentage of the tomato fruits were determined. Additionally, fungi associated with the postharvest deterioration of the fruits were isolated and identified using standard procedures. From the results of this study, tomato fruits coated with either neem or moringa crude extract showed the longest shelf life, as compared to the coating with AgNPs. Additionally, two fungi, namely Aspergillus niger and Aspergillus flavus, were isolated from the decayed tomato fruits. In conclusion, the neem and moringa leaf extracts are effective in the extension of the shelf life and retention of the quality of tomato fruits.
