In this paper, phytic acid(PA)was added into culture broth, the effects of PA on rice wine were studied. The conclusions as follows: ①The optimum PA concentration was 0.10%, alcoholic strength could raise 13.16% markedly at the end of fermentation; ②PA accelerated yeast proliferation and advanced exponential phase, raise gemmating rate, reduced death rate, and speed fermentation rate; ③Adding PA, the alcohol tolerance of yeast advanced 4% from 16% to 20%; ④PA shorted fermentation cycle, improved Chinese rice wine ingredients, and increased yield and quality.
