Abstract:

In order to improve the quality of Pinot Noir dry red wine, Pinot Noir grape was selected as raw material, single strain of Schizosaccharomyces pombe (S. pombe) was used to inoculate and fermentate in alcohol with commercial Saccharomyces cerevisiae(S. cerevisiae) simultaneously and sequentially, and S. cerevisiae alone was inoculated with alcoholic fermentation followed by malolactic fermentation as the control. The changes of malic acid and biogenic amines during the fermentation process were monitored. Headspace solid phase microextraction combined with gas chromatography-mass spectrometry was used to analyze the changes of volatile aroma substances, and the sensory evaluation was carried out. The results showed that the fermented residual sugar, alcohol content, total acid and volatile acid of S. pombe inoculated simultaneously and sequentially with S. cerevisiae all met the requirements of national standard GB15037-2006 “Wine” for dry red wine. Alcohol fermentation could be realized by S. pombe alone and simultaneously or sequentially with S. cerevisiae. Compared with the control group, the inoculation method in the treated group could significantly reduce the content of malic acid and histamine in wine, among which, the contents of malic acid and histamine in the wine sequentially by S. pombe and S. cerevisiae were significantly lower than those inoculated by S. pombe alone and simultaneously with S. cerevisiae. The sequential inoculation fermentation of S. pombe and S. cerevisiae can significantly enrich the alcohols, esters and terpenes in the wine, so that the wine has strong fruit aroma and floral fragrance. Sensory analysis showed that the sensory quality of S. pombe and S. cerevisiae wines sequentially was superior to that of other treatment groups. In summary, sequential inoculation fermentation of S. pombe and S. cerevisiae can increase the alcohol, ester and terpene substances in Pinot Noir dry red wine, reduce the content of malic acid and improve the taste of wine.
