Original Abstract
The aim of this work was to find the best composition for fruit drink based on elderberries. For this purpose elderberry juice was mixed with various fruit juices in various ratios, flavour was evaluated sensorially and instrumentally as the content of aroma compounds. Five flavour characteristics (sweet, acid/sour, bitter, astringent, characteristic elderberry), off-flavour, odour, texture (mouth-feel), colour and overall acceptability were evaluated sensorially using scale. Aroma compounds were extracted by SPME (solid phase microextraction) and assessed by gas chromatography with flame ionization detection (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The significant differences (P < 0.05) in flavour were found between samples, which could be explained by differences in their volatile profiles. In total 57 compounds were identified in fruit juices and included 20 alcohols, 10 aldehydes, 8 ketones, 7 acids, 7 esters and 5 other compounds. Alcohols were quantitatively the most important group of all juices. The grape-elderberry juice, in optimum ratio 7:3 (70% v/v of elderberry), was proposed for practical use owing to the pleasant sweetish, elderberry flavour, and excellent other sensory characteristics.
