Abstract
Pitaya or dragon fruit (Hylocereus spp.) has been gaining an important demand and popularity in tropical and sub-tropical regions of the world, mainly because of its high antioxidant activity and diverse nutrients.
However, dragon fruits have a thin rind which makes them very prone to water and quality loss during storage.
Therefore, this research was carried out to determine the impacts of potassium sorbate (PS) and edible coating (EC) treatments separately and in combination with the modified atmosphere packaging (MAP). A total of 6 treatments were tested in current research, namely: 1) control, 2) EC, 3) PS, 4) MAP, 5) MAP + EC, and 6) MAP + PS. Fruits were stored at 10-11°C and 90-95% relative humidity.
According to the results obtained, fruits with no treatment had a total of 22.9% weight loss in 35 days, which was maximally reduced to 11.6% with the combination of MAP and PS treatments.
The same treatment was noted to have the highest influence on the preservation of the loss in soluble solids concentration and to have the highest impact on the prevention of fruit decay.
In conclusion, results revealed the highest impact of MAP on the preservation of the fruit quality during storage and highlighted that the combination of MAP with PS or EC produces better results in the prevention of postharvest losses.
