- Аннотация: The effect of biol. fractionation of the stable isotopes of oxygen 18O/16O in the intracellular water of apples and pomegranates grown in Russia and Azerbaijan was first studied. The research was carried out using the IRMS/SIRA technique of isotopic equilibration. It has been proved that for five varieties of apples grown in the Russian Federation the level of the δ18OVSMOW in the intracellular water of the processed apples in 2012 season is equal to -5.47 through -0.36‰; that for seven varieties of pomegranates grown and processed in Azerbaijan is equal to -3.93 through +0.26‰. The results obtained coincide with the previously published data of δ18OVSMOW changes in the intracellular water of pomegranates grown and processed in Azerbaijan in 2011. The results of the study can be of practical use for the quality evaluation of the industrially produced fruit juices as well as for the detn. of their geog. origin. The results of the study can also be applied to identification of products supplied at the national, regional, and international markets and labeled as "NfC Apple juice"/"NfC Pomegranate juice". This identification might be held in the area of juices and juice related products according to the known quality evaluation protocols & systems (e.g. IMAS, EQCS) and with the use of such ref. documents as Code of Practice AIJN.
