Abstract: In order to improve the quality of the biberrg apple blended fruit wine, the effects of four kinds of clarifying agents, including bentonite, gelatin, polyvinylpyrrolidone(PVPP)and egg white powder, on the clarification effect, physical and chemical indicators, aroma components and sensory evaluation of bilberry apple blended fruit wine were studied. The results showed that the light transmittance was significantly increased by 8.1%-9.4% after clarification. There was no significant change in the physicochemical indicators of each wine sample. A total of 118 aroma components were detected by headspace solid-phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS), including 23 alcohols, 13 acids, 43 esters, 4 phenols, 6 ketones, 7 aldehydes, 4 terpenes, 9 alkanes and 9 other aroma components. The sensory evaluation showed that the 0.6 g/L bentonite treated wine had a pleasant and harmonious appearance and the highest sensory score. The comprehensive evaluation determined that 0.6 g/L bentonite was the best clarification scheme for bilberry and apple blended fruit wine.

Key words: bilberry apple blended fruit wine, clarifying effect, physical and chemical indicators, aroma components, sensory evaluation
