The Effects of Different Package Openings on Storage of ‘Red Globe’ Grape Variety
Abstract
Objective: In this study, it was aimed to determine the effects of different openings onto the polyethylene (PE) packages used in storage of ‘Red Globe’ grape variety on sulfur dioxide (SO2) damage and quality of grapes.
Material and Methods: The grapes placed in PE bags with ‰0 (control), ‰0.5, ‰1 and ‰2 openings. After pre-cooling grapes in the case of SO2 generators were placed after the mouth of the bags were closed with clips. Grape fruits were stored at 0±0.5°C and 90-95% relative humidity for 4 months. SO2 concentrations in packages and some quality parameters monitored and analysed during the storage.
Results: SO2 concentrations detected at the end of storage in PE packages with ‰0, ‰0.5, ‰1 and ‰2 openings were 33.50, 22.00, 5.00 and 2.33 mg/kg respectively. It has been found that grapes in packages without opening had significant color changes, softening due to the SO2 damage. However, grapes in packages with ‰2 openings had high browning scores in stems.
Conclusion: The results showed that ‘Red Globe’ grapes could be stored more successfully in PE packages with ‰1 openings.
