| Summary: | The goal of this study was to determine whether the quality of fruit nectars and wines available on the local market is in accordance with the quality prescribed by the Rulebook. The research involves analysis of blueberry, strawberry, peach, apple and orange fruit nectars from two companies (C1 and C2), and samples of red wines from three wineries (W1-3). The following quality parameters were determined: soluble solids content (% Brix), actual acidity (pH) and titratable acidity in the nectars, and actual acidity (pH) and titratable acidity in the wines. All samples of fruit nectars met the prescribed % Brix requirements. Titratable acidity, expressed in g dm-3 citric acid, in C1 blueberry and strawberry nectars deviated from the values laid down in Rulebook 2 (Rulebook on the Quality of Fruit Juices, Concentrated Fruit Juices, Fruit Juice Powder, Fruit Nectars and Related Products- Official Gazette of RS Issue No. 27/2010). Deviations were detected in C2 orange nectar. The total acid content in the analyzed wine samples, expressed in g dm-3 of tartaric acid, corresponded to the values prescribed in Rulebook 1 (Rulebook on Quality and Other Requirements for Wine - Official Gazette Issues Nos. 54/99 and 39/2002, Official Gazette Issue No. 56/2003 - other Rulebook and Official Gazette Issue No. 87/2011 - other Rulebook and 26/2015 - other Rulebook). |
