Description The sweet sorghum varieties were screened for their suitability for beer production
based on the amylase activity and reducing sugars of malted grains. Standardization of the
parameters for malting and mashing were also carried out along with optimization of
fermentation parameters for good quality beer production. The variety “SSV-84” showed the
highest amylase activity (1266.10 μg protein/15 min/g sample) and reducing sugars (33.85
mg/g) for a soaking period of 16h and germination period of 3 days which was followed by
‘DSV-2’, ‘SSV-108’ and SSV-74’. The ‘SSV-84’ variety was further used to standardize
other parameters. The commercial a-amylase (MAPS India Ltd., Ahmedabad) was used
during mashing process, at a concentration of 1 per cent at 70°C for an incubation period of
24h which released maximum reducing sugars (78.83 mg/g) than other treatments. Five
strains of yeast were screened for fermentation of the above hydrolysate and the optimization
of the inoculum level and fermentation period were carried out. Among the inoculum levels
used (1%, 1.5% and 2%), the pH, tannin content and residual reducing sugars of beer
decreased significantly upto 2 per cent inoculum. The alcohol content increased as inoculum
level increased. Similarly, in case of the different fermentation period (5 days, 7 days and 10
days), significant decrease in the pH, tannin content and residual reducing sugars was
observed upto tenth day, and alcohol content had increased significantly. Among the yeast
strains, Saccharomyces cerevisiae NCIM 3580 performed best when inoculated at 2 per cent
inoculum level for a fermentation period of ten days. The final beer produced was compared
with the commercial beer and was favourable when evaluated organoleptically.
