The study on the technique of new style vinegar with Lentinus Edodes

In order to develop the value of Lentinus Edodes root,wasted roots of Lentinus Edodes are used as raw materials.After cellulose enzymolysis,processed roots of Lentinus Edodes undergo the alcohol fermentation and acetic acid fermentation to produce vinegar.After optimizing the enzymatic hydrolysis conditions,the optimal parameters are set as the followings:the concentration of zymosis substrate is 5%,enzyme is 400 FPA/dL,pH degree is 5.0,temperature is 50℃,the liquid volume in acetic acid fermentation is 50 mL,rotating speed is 100 r/min,shaking incubation is 5 d and the concentration of final vinegar with Lentinus Edodes is 4.18 g/dL.
