Abstract: Ganoderma Lucidum as raw material,the fermentation conditions of Ganoderma Lucidum vinegar beverage were studied by means of extracting and fermenting with Yeast and Acetobacter.The results showed that the optimum extracting conditions and time were 0.1 MPa and 1.0 h,and water and Ganoderma Lucidum ratio 20:1.After second extracte, the amount of polysaccharides reaches 1.25 mg/ml.In Alcohol and Acetobacter fermentation phases,the optimum fermen- tation conditions were obtained:inoculating amount of liquid seed 10%,30℃,72～80 h and 34～36℃,pH 5.5,shaker speed 150 r/min,for 72 h.A sour and sweet and tasty vinegar beverage is produced after adding 6.5% white sugar or 0.3% proteinic sugar to the fermented liquid.
