果粮混酿苹果醋最佳工艺的研究

Optimal Process Conditions of Vinegar by Using Fruit-Grain Mixture

以苹果汁与大米糖化液为原辅料,酵母茵和醋酸茼作为发酵菌种。深入探讨了酒精发酵与醋酸发酵的工艺条件。结果表明:最佳条件为苹果汁与大米糖化液比例1∶1,调整糖浓度12%、酒精发酵7d、醋酸发酵6d、酒度7°,接种量10%、培养温度30℃及后熟1周。

Using apple juice and grain saccarification liquid as raw material, process c conditions of alcoholic and acetic acid fermentation were discussed deeply with yeast and acetic acid bacteria as main zymogen. Optimal process conditions followed： ratio of apple juice and grain saccarification liquid was 1： 1, sugar concentration was 12%, alcoholic and acetic acid fermentation time were 7 and 6d, respectively, alcohol content was 7°, inoculum concentration was 10%, temperature was 30℃, and postripeness was 1 week.
