The pH of the samples was checked immediately after extraction, and
there was a significant decrease, hence acidic fermentation was taking
place. This study revealed that wine production from jackfruit juice by
fermentation using Saccharomyces cerevisiae can be done in less than
two weeks. It has also been seen that alcohol production is affected
by various parameters. The result of the various tests performed was
tabulated and is given in Tables 1 and 2. The cumulative percentage of
alcohol produced on 7th, 14th and 21st day is shown in Figure 1
