Effects of fruit juice concentrate production on individual anthocyanin species in elderberry

Summary Elderberry concentrate is widely used for food colouring. Its production includes several processing steps, which influence pigment composition, thus affecting the quality of final product. In this study, qualitative and quantitative changes in anthocyanin components were followed during the production of elderberry juice concentrate using Haschberg and Samocco varieties. Juice concentration resulted in more than five-fold concentration increase in anthocyanins; however, clarification, filtration and evaporation steps caused slight but continuous decrease in anthocyanins relative to the dry matter of the product. Pectolytic enzymatic treatment was found to be one of the most critical processing steps that affects anthocyanin yield during production, and this effect on yield can be variety-dependent. Additionally, two condensed dimeric anthocyanin species generated after heat treatment are reported for the first time to be present in elderberry juice concentrate. Our results suggest that cyanidin-based anthocyanin conjugates with more complex saccharide moieties are more robust during production.
