Abstract
This study was conducted to test the possibility of improving the storability of Alba squash fruits with the applications of modified atmosphere packaging (MAP) alone or in combination with essential oils of Origanum syriacum. Studies were conducted with four treatments and 15 replications that were used for each treatment.
All fruits were washed with pure water for 1 min and then air-dried for 30 min before the experiments.
The treatments of this study are i) MAP, ii) MAP + EO (0.1 mL O. syriacum bag‑1), iii) MAP + EO2 (0.5 mL O. syriacum bag‑1), and iv) control (no additional application except washing). After the application of the treatments, fruits were stored at 8±1°C and 95% relative humidity for 15 days.
Quality parameters were measured with 5-days interval.
Five fruits were taken out at each measurement day and the parameters were measured.
Results showed that the modified atmosphere packaging is very beneficial in preserving the storage quality of squash fruits.
It was noted that the weight loss of control fruits reached 19.6% in 15 days, while at the same time, the weight loss of the fruits treated with MAP, MAP+EO and MAP+EO2 were only 9.7, 7.9 and 9.7%, respectively.
These results suggested that the incorporation of essential oil of O. syriacum into the MAP bags is a better way for storing the squash fruits.
Similar results were noted for other quality parameters, such as fruit firmness, soluble solids concentration, titeratable acidity, chlorophyll content and carotenoid content.
Overall, results suggest that the modified atmosphere packaging is an important application for the improvement of the storage quality of squash fruits, while the incorporation of O. syriacum oil into the bags could improve the benefits of MAP bags.
