Abstract:
In this research, the effect of plastic coating impregnated with titanium dioxide nanoparticles on the post-harvest quality of seedless white fruit cultivars, Qezel Ozum and RishBaba during cold storage was investigated. For this purpose, healthy, uniform and free from any physical damage and microbial decay grape bunches were packed using polyethylene wrappers impregnated with titanium dioxide nanoparticles and stored for 80 days in a cold store with a temperature of 0±1°C and a relative humidity of 90±5%. The characteristics of total soluble solids, titratable acidity, ripening factor, pH and total phenolic content of grapes were measured at 20-day intervals. The statistical analysis of the results showed that the treatment of titanium dioxide nanoparticles had a significant effect in reducing the titratable acidity, pH, total phenol content and ripening coefficient compared to the control samples. The samples treated with titanium dioxide nanoparticles showed higher soluble solids and titratable acidity. The results showed that all three grape cultivars packed with polyethylene wrappers impregnated with titanium dioxide nanoparticles had higher quality than the control samples at the end of the storage period.
