The study was carried out in 2014 and 2015, and aimed to determine some important biochemical and antioxidant characteristics of the fruits of mulberry (Morus spp.) cultivars and genotypes found in Malatya (Turkey). Phenolic compounds (protocatechuic acid, vanillic acid, ellagic acid, rutin, quercetin, gallic acid, catechin, chlorogenic acid, caffeic acid, syringic acid, p-coumaric acid, o-coumaric acid, phloridzin and ferulic acid), organic acids, sugars, vitamin C and antioxidant capacity were analyzed in sampled fruits. The results showed that most of the biochemical content and antioxidant capacities of the cultivars and genotypes were significantly different from one another (p < 0.05). Among the phenolic compounds, rutin (118.23 mg 100 g ) were determined to have the highest values for most of the fruit samples. Malic acid and citric acid were dominant among the organic acids for all the cultivars and genotypes except 44-Nrk-05. Glucose was measured as a more abundant sugar than fructose and sucrose in all samples. Antioxidant capacity, on the other hand, varied between 6.17 and 21.13 µmol TE g -1 among the cultivars and genotypes analyzed.Ke y wor d s: cultivar, genotype, mulberry, phytochemicals

“…The arils are comprised of approximately 80% juice and 20% seed. The juice of arils contain 85% water, 10% total sugars (glucose, sucrose, and fructose) (Melgarejo & Artes, 2000), and 1.5% pectin, organic acids (citric, malic, tartaric, succinic, fumaric, ascorbic acid) (Tezcan et al, 2009), fatty acids (i.e. conjugated linoleic acid, linoleic acid, punicic acid and eleostearic acid) (Fadavi et al, 2006) and amino acids (i.e.…”

“…Pomegranates have been classified into three varietal groups (sweet, sour-sweet, and sour) based on sensory characteristics and sugar and acid compositions (Cemeroglu, Artik, & Erbas, 1992;Melgarejo, Salazar, & Artes, 2000). In the Southeast region of Turkey, the sour and sour-sweet varieties are mainly utilized in concentrated form.…”

“…In the Southeast region of Turkey, the sour and sour-sweet varieties are mainly utilized in concentrated form. The chemical composition of pomegranates has shown significant variation based on cultivar, growing region, maturity, environmental conditions, and storage and handling practices (Cemeroglu et al, 1992;Cemeroglu, Artik, & Yunculer, 1988;Melgarejo et al, 2000;Mirdehghan & Rahemi, 2007;Unal, Velioglu, & Cemeroglu, 1995 the adulteration of pomegranate juice and pomegranate juice concentrate (PJC) with the less expensive grape juice concentrate (GJC) has become a concern. Therefore, analytical techniques are needed that are able to detect this type of adulteration, even in the presence of chemical composition variations.…”

Fourier transform infrared (FTIR) spectroscopy and chemometric techniques were used to detect the adulteration of pomegranate juice concentrate (PJC) with grape juice concentrate (GJC). The main differences between PJC and GJC infrared spectra occurred in the 1780-1685 cm À1 region, which corresponds to C@O stretching. Principal component analysis of the spectra was used to: (1) differentiate pure PJC and GJC samples and (2) classify adulterated (containing 2-14% vol/vol GJC) and pure PJC samples. Two principal components explained 99% of the variability in each of these applications. Partial least square analysis of the spectra resulted in prediction of the GJC adulterant concentration in PJC with a correlation coefficient, R 2 , of 0.9751. Partial least square analysis of spectra could also predict % titratable acidity and total solids in PJC with correlation coefficients of 0.9114 and 0.9916, respectively. Therefore, FTIR and chemometrics provide a useful approach for authenticating pomegranate juice concentrate.
