Research on Breeding of Navel Orange Wine Dry Yeast Strain

Y1980 yeast strain, separated from navel orange juice (the juice produced by natural fermentation, was used in navel orange fruit wine production with navel orange as raw materials. Its fermentation performance indicated that since the second day, sugar content decreased greatly and alcohol content increased rapidly, after 8 d in primary fermentation, sugar content and alcohol content changed no more, and residual sugar content decreased to 5 g/L, besides, the acidity in fermentation changed in mild trend. The evaluation of fermentation performance and the judgement of product wine taste proved Y1980 strain more suitable for navel orange wine production. (Tran. by YUE Yang)
