Evaluation of fruit physicochemical properties in some peach cultivars

Abstract

Detailed information about fruit chemical properties is very important forunderstanding the product behavior during the delivery chain. The present study wascarried for determining some chemical and physical properties of fruit such as titratableacidity, pH, total soluble solid (ºBrix), Vitamin C, dry matter (%), fruit water content (%),ash (%) and fruit mass in 8 peach cultivars: ’Zoodras’, ‘Khouni-haste-joda’, ‘Kosari’,‘Anjiri-ye-tabestane’, ‘Anjiri-ye-maleki’, ‘Anjiri-ye-khouni’, ‘Haj-kazemi’, ‘Haste-joda’.Results showed significant differences between studied cultivars, in all of propertiesexcept ash (%). The highest Brix and dry matter and the lowest fruit water contentbetween studied cultivars were corresponded to ‘Anjiri-ye-khouni’. In general, ’Zoodras’had the lowest Total soluble solids (TSS) and the highest fruit water content. Totalsoluble solid content of these eight cultivars are ranged from 11.50 to 17.33 ºBrix. Thehighest vitamin C and titratable acidity and the lowest pH were corresponded to ‘Khounihaste-joda’. ‘Anjiri-ye maleki’ had the highest TSS/Ta ratio and the lowest acidity andvitamin C content.
