Extraction of sugar and acid from dried Haihong fruit with distilled liquid
摘要
Abstract
In order to full use of distilled liquid from Haihong brandy production ,make waste profitable ,dried Haihong fruit was added into the distilled liquid to extract sugar and acid in it by a thermal extraction way ,so as to subsequent alcohol fermentation and acetic acid fer‐mentation with the distilled liquid .The factors affacting on total concentration of sugar and acid in the resultant extracted liquid were investigated ,including the mass‐volume ratio of dried fruit to distilled liquid ,extraction time ,extraction temperature and pectinase addition . Based on single factor experiments ,extraction conditions were optimized by a orthogonal test .The optimal extraction conditions are the mass‐volume ratio of dried fruit to distilled liquid of 1∶5 ,extraction time of 24 h ,extraction temperature of 50 ℃ ,pectinase addition of 0 .3 g/L .Under these conditions ,the content of total sugar in obtained juice is 79 .91 g/L , and the content of total acid is 7 .26 g/L .The content of the total sugar and total acid are in‐creased by 77 .16 g/L and 5 .18 g/L respectively .关键词
