Quality of tomato fruits (Solanum lycopersicum) coated with tomato seed oil during storage was evaluated.Oil was extracted using solvent extraction method (n-hexane) from dried seeds of two varieties of tomato fruits, of Roma VF (Ra) and Riogrande (Rg).Healthy fruits of the two varieties of tomato were harvested at breaker stage by hand picking from the experimental farm and coated with the tomato seed oil (TSO) and stored at room temperature ranging from 25.9 -35.0 ˚C.The oil yield for both Riogrande and Roma VF is at 35 % and 38 % ( w /w) on a dry weight basis.Other results indicated that the shelf life, vitamin C content, Beta carotene and lycopene content of the treated tomato fruits for both varieties increased from days 0 to 20 while the controls increased from days 0 to 12.The treated fruits showed a statistical difference (p< 0.05) in firmness when compared to untreated (control) fruits on Days 12 (Rg 0.35,Ra 0.15) and 16 ( Rg 0.45, Ra 0.15) while the other days of storage showed no significant differences at ambient conditions.The results of this study established that both oil extracted from the seeds of Riogrande and Roma VF varieties of tomato fruits possess natural preservative that increase the shelf life and maintain the physicochemical quality of tomato fruits during storage.
