Özet

© by PSPThe objective of this study was to investigate an alternative consumption (dried on the tree) for medlar which is very important functional fruit recently. In the study, phytochemical changes were assessed at different harvest time additionally. For this purpose, the fruits were harvested at 4 different ripening periods in 2017 and 2018; 170, 200, 216 and 280 days (dried on the tree) after the full blooming. Total phenolic content, free radical scavenging capacity (DPPH %), total anthocyanin and total vitamin C of the fruits harvested at different periods were examined. The studied parameters did not show any change over the years; total phenolic content (144.69 mg/100g-106.28 mg/100g 2017; 137 mg/100g-101.86 mg/100g 2018), DPPH% (24.99-18.88% 2017; 22.21-18.79% 2018) and vitamin C (16.22 mg/100g, 12.46mg/100g in 2017; 14.22 mg/100g - 11.96 mg/100g in 2018) contents decreased, while the total anthocyanin (23.75 mg/L-32.27 mg/L, 2017; 23.65 mg/L-29.89mg/L) increased with the maturity in both years. Additionally, a correlation between the total phenolic content and DPPH% has been discovered in 2017 and 2018 respectively (R2=0.75 and R2=0.22). According to the results, dried on the tree-medlar can be recommended as a new consumption.
