Abstract: In this study, it was analyzing some chemical characteristics and mineral composition of juice and madzun (grape molasses) produced from Stanushina grape variety by traditional method. Madzun (grape molasses) is a natural sweetener widely consumed in the R. N. Macedonia in the past decade and mostly in Eastern Mediterranean countries. It is an important food for humans in terms of mineral content and high energy content (carbohydrates). Comparative analyses have been conducted to one sample juice (S1) and two (S2, S3) samples madzun. As a result of research: soluble dry matter 29.41 (juice)-82.98% (madzun), total sugar 28.04 (juice)-67.99% (madzun), total phenols 875 (madzun)-1212 mg/L (juice) and HDM (hydroxymethyl furfural) were detected in the range of 5.25 mg/kg (juice) to 723.05 mg/kg (madzun). In the samples, the macro minerals K, Ca and Mg are ranged from 386-640 mg/kg (S1)- 111.7-375 mg/kg (S3), 111.7 mg/kg (S3) –375 mg/kg (S1) and 205.5 mg/kg (S2)-297 mg/kg (S1), respectively. Of the microminerals Fe 11.26-15.18 mg/kg, Mn 2.42-4.90 mg/kg, Zn 7.34-17.47 mg/kg, B 35.2 – 39.9 mg/kg and Ba were found between 0.35-0.84 mg/kg. Regarding the content of heavy metals (Pb and Ni), sample C1 and C2 are above the permissible limits for this type of food. Concentration of metals in grapes is influenced by the microregion of origin and type of soil.
