RESUMO

This study investigates the impact of bee pollen on volatile compounds, odour activity values and sensory profiles in Palomino fino and Riesling young white wines. Commercial bee pollen was added to grape must using six different doses (0 (control), 0.1, 0.25, 1, 5, 10 and 20g/L) and fermented under controlled conditions. Volatile compounds were determined with GC and GC-MS chromatography and sensorial analysis using a qualified panel of tasters. Bee pollen produces an increase in volatile compounds depending on the grape variety and the dose applied. It also increases the synthesis of higher alcohols, methanol, esters, acetaldehyde and terpenes, reducing alcohols and fatty acids. Wines with low doses (0.1 and 0.25g/L) showed the higher OAV values (fruity and floral) and scores in overall judgment for the sensory evaluation. High pollen doses decrease fruity character and could result in deviations affecting the sensorial quality.
