The Influencing Factors on the Production of Alcoholic Drinking from Jackfruit (<i>Artocarpus heterophyllus</i> L.)

Abstract

The large amount of jackfruit (Artocarpus heterophyllus Lam) harvested and their short use time caused many difficulties for the farmers. Fortunately, the high sugar content in jackfruit meat is a hopeful substance for wine production. This study aimed to consider the effect of yeast strains and their concentration on fermented jackfruit solution. Jackfruit juice with 14 °Brix is ​​fermented using 0.005 to 0.015% (w/v) Saccharomyces cerevisiae RV002, Mauri Instant Dry Yeast yeast under anaerobic conditions for 1 to 4 days at 30 °C. Survey samples were checked once a day to analyze the indicators. The functional report of the sugar in the fermentation time, shows that the higher incidence of yeast cultures and the initial sugar concentration inhibited yeast growth. The results showed that fermentation from jackfruit meat with 25 °Brix using Saccharomyces cerevisiae RV002 yeast with concentration of 0.01% for 3 days is the best to create a good quality with ethanol content 4,9% and characteristic aroma of jackfruit.
