Abstract
The fermentation of cider by mixed cultures of Wickerhamomyces anomalus and Saccharomyces cerevisiae was carried out to study their effect on the cider quality. The results showed that growth of W.anomalus and S.cerevisiae was affected by each other during co-fermentation process. All the mixed cultures produced statistically the same level of ethanol as S.cerevisiae monoculture. The mixed fermentation could produce more variety and higher amounts of acetate esters, ethyl esters, higher alcohols, aldehydes, and ketones. Sensory evaluation demonstrated that ciders obtained from co-fermentation with W.anomalus gained higher scores than ciders fermented by pure S.cerevisiae, especially the co-fermentation cultures WS3, WS4, WS6, and WS8. Only 3days of fermentation with W.anomalus in sequential mixtures were enough to improve the quality of cider. Wickerhamomyces anomalus could be used in association with S.cerevisiae to improve the quality of cider. The modulation of inoculation time may provide an effective means of manipulating cider aroma for different characteristics.
