INFLUENCE OF PRODUCTION SYSTEM AND MODIFIED ATMOSPHERE STORAGE ON QUALITY PARAMETERS OF ‘SUNBURST’ CHERRIES DURING STORAGE

In the present study, cherries (‘Sunburst’) from integrated (IP), ecological (EP), and control production (no treatment applied, CP) were stored in X-tend film at +1°C for 20 days and additional 2 days at 10°C. The IP refers to selective use of insecticides and fungicides, in EC only for this production permitted means were applied while no treatments were used in control production.
After harvest, fruits were stored in modified atmosphere and analysed on microbiological decay, weight loss, respiration rate, residues of phytopharmaceutical products, titratable acidity (TA), total soluble solids (TSS) and content of ascorbic acid at harvest and after storage.
Weight loss amounted to 0.4% for control fruits but was lower for IP and EP treatment.
The faster increase of CO₂ and decrease of O₂ was observed for fruits from IP while there were no differences between control and EP. After 22 days of storage, control production resulted in the highest ratio of microbiological spoilage (20%), meanwhile no statistically significant differences were found between IP and EP, i.e., 7.3 and 5.0%, respectively.
Ascorbic acid content was in slight decrease during storage, fruits from EP contained more ascorbic acid as compared to CP and IP. Regarding residues of phytopharmaceutical products in IP treatment after harvest the content of insecticide phosmet and fungicides iprodione and fenhexamide were found to be below regulation limits and their content did not change during storage period.
