PRODUCTION OF WINE FROM FERMENTATION OF WATERMELON AND PINEAPPLE

Abstract

Mixed fruit wine (pineapple and watermelon) was produced using Saccharomyces cerevisiae isolated from palm wine. Primary and secondary fermentation of the fruits lasted for 7 and 28 days respectively, during which aliquot samples analysis of pH, titrable acidity, specific gravity, alcohol content and reducing sugar were carried out using standard procedures. Specific gravity of the wine was observed to reduce drastically as the fermentation progresses. The pH of the fruit must during the period of fermentation ranged from 3.0 to 4.46. During the fermentation period, consistent increase in alcohol content was observed with time. At the end of the 28th day of fermentation, the alcohol content was observed to be 3.2%. The titrable acidity of the wine was observed to show steady trend with time throughout the period of fermentation. This study showed that acceptable wine can be produced from mixed fruits pineapple and watermelon using yeasts especially Saccharomyces cerevisiae isolated from palm wine.
