The aim of the present study was to establish the possibilities of using the locally available fruit for
wines production. Pawpaw wine was produced by fermenting pawpaw pulp supplemented with 30% sucrose
using Saccharomyces cerevisae purchased from E. C Kraus USA. Aerobic fermentation was carried out for six
days while anaerobic fermentation was for six weeks at 29±2ºC. During aerobic and anaerobic fermentations,
changes in pH, Titratable Acidity (TTA), sugar content, alcohol content, specific gravity, total yeast counts and
total heterotrophic counts were monitored. During the aerobic fermentation, the pH dropped from 4.4 to 3.1,
titratable acidity increased from 0.2 to 0.4, specific gravity dropped from 1060 to 996 sp.gr. Alcohol content
increased from 0 to 8.0%, Sugar content dropped from 15 to 1%, total yeast counts increased from 0 to 4.75X106 cells/ml while total heterotrophic bacterial count ranged from 5 to 50 cfu/mL. Two bacterial species:
Lactobacillus plantarum and Pediococus pentosaceus were encountered. During anaerobic fermentation pH
ranged increased from 3.2 to 3.6, TTA decreased from 0.4 to 0.19, specific gravity dropped from 995 to 992
sp.gr. Yeast population droped to 2.5×104 cells/mL by week 3, sugar was not detected and the final percentage
alcohol was 9.8%. Pediococus pentosaceus resist during anaerobic fermentation. Sensory evaluation shows
70% acceptance compared to imported red wine (90%).
