The invention relates to a method for producing sorbose. In the method, the initial sorbic alcohol concentration is controlled to be 130 to 160 g/L, the sorbic alcohol is started to be added in a flowing way when the residual sorbic alcohol concentration in zymotic fluid is lower than 100g/L, and the sorbic alcohol concentration in the zymotic fluid in the feeding process is controlled to be 100 to 150 g/L. At the end point of the fermentation, the sorbose content reaches 300 to 330 g/L, the alcohol sugar conversion rate is 99 to 100 percent, the utilization rate of the production equipment is improved, and the production cost is reduced.
