Optimization of Production Technology of Low Miscella Alcohol Passion Fruit-Dragon Fruit Complex Wine
Passion fruit juice and dragon fruit juice are used as raw materials to brew passion fruit and dragon fruit complex wine.Through single factor test and orthogonal test,the optimal fermentation process is determined as the volume ratio of passion fruit juice and dragon fruit juice 1∶1,pectinase addition 0.02%,fruit wine dry yeast addition 0.09%,ammonium sulfate addition 0.04%,fermentation temperature 24℃,fermentation time 15 days.The content of methanol and fusel oil are 300 mg·L-1 and 510 mg·L-1 respectively in the fruit wine fermented under the best conditions.This study provides theoretical basis and technical support for the industrial production of passion fruit-dragon fruit composite wine.
