Özet

This study was carried out to determine the physical and biochemical changes in fruits harvested at three different maturity stages in pomegranate cultivar 'Hicaznar'. Fruits were harvested at the periods of 1) the time of the beginning of the color change in arils (August 15), 2) the time of the pink color of arils (September 6) and 3) the time of the red color of arils (October 3). In the study, fruit weight, fruit juice, colour (L*, a*, b*), titratable acidity, pH, total soluble solids, total phenolics, phenolic composition (gallic, chlorogenic, ellagic and syringic acids) and organic acids (malic and citric acids) were investigated. Significant increases in fruit weight, total soluble solids, malic acid and colour value of a* were detected with progress of maturity. On the contrary, titratable acidity, total phenolics, gallic, ellagic and sitric acids were significantly decreased with progress of maturity. The changes in chlorogenic and syringic acids were not statistically significant.
