Abstract: Phytic acid (PA) was applied in Rosa roxburghii Tratt wine for studing the effects on yeast growth and propagation and fermentation of the wine. The results were as follows: (1) PA shortened the fermentation time, reduced the sugar residue and increased the alcohol content; (2) PA accelerated the yeast growth and proliferation, advanced the logarithmic growth phrase and promoted the yeast gemmation; (3) PA improved the alcohol tolerance of yeast; (4) The optimum PA concentration was 0.08% in.the test.

Key words:  , phytic acid(PA); Rosa roxburghii Tratt wine; yeast; fermentation;
