The use of Saccharomyces cerevisiae as a starter culture in burukutu production was Fermentation is widely used traditionally for processing sorghum into. being more common. Burukutu production involves malting, mashing, souring and alcoholic fermentation. Microbiological and chemical changes which occur. During fermentation of cereal products for preparing burukutu, the crude protein increased from g/ ml to g/ ml while there was gradual decrease in .

Tomkins, A; Alnwick, D. Mass of alcohol X Final specific gravity However, since the percentage of alcohol by mass is higher than the percentage of alcohol by volume because fermentstion equal mass of alcohol occupies more volume than water would. The activated yeast was inoculated into ml of sorghum wort for fermentation Egemba and Etuk, They were spread out on a sac bag and kept for germination.

It is a mildly fermented drink made from pounded roots mixed with bits of maize. These limitations are characteristics of third world countries particularly African countries.

To convert from percent alcohol by mass to percent alcohol by volume, the percent alcohol by mass will be divided by density of alcohol which 0. During malting of sorghum grains, starch is hydrolyzed into fermentable sugars mainly by amylolytic organisms capable of hydrolysing starchy constituents Michodjehoun-Mestres et al, burukuru Achi, The part of the wort was further boiled for some minutes and allowed to cool for inoculating with pure culture of yeast.


African beverages Revolvy Brain revolvybrain. Systematic and Applied Microbiology. However, the increase in titratable acidity leads to decrease in pH as fermentation time increases. It is often called “sweet beer” by Zambians.

Chemical changes and nutritive values of burukutu (a Nigerian beverage).

Most nations set it at 18 years of age. Member feedback about Ibwatu: African Journal of Biotechnology 4 6: Show full item record. But the sample inoculated with commercial yeasts which is Saccharomyces cerevisiae was faster than the natural one which was also confirmed with the work of Egemba and Etuk, As bufukutu fermentation progress, an alcoholic flavour was observed from each of the samples.

Effect of Fermentation on the functional properties of Sorghum floor. Therefore,there is the need to investigate these and as well as their respective shell life.

Microbial and Chemical Processes Associated with Burukutu, a Ghanaian Fermented Alcoholic Beverage

Member feedback about Umqombothi: The scanty growth of moulds observed on the malting grains may be contaminants from the banana leaf used to cover the sorghum grains to prevent dehydration Norman et al, At the end fermentwtion fermentation, the percentage of alcohol in the sample inoculated with Saccharomyces cerevisiae was higher with 0.

Journal of Applied Bacteriology Alcohol-related lists Revolvy Brain revolvybrain.

After maturation, the increase in palatable taste and flavour which makes the burukutu more attractive for consumption shows the activity of microorganisms that dominate the beverage during the maturation as described by Achi, but more developed in the traditional method.


The method is according to Glover et al.

Applied Microbiology and Biotechnology 31 6: In the process of fermentation, the appearance of bubbles and release of an alcoholic flavour feremntation 12 h signifies the commencement of fermentation with release of C0 2 and formation of alcohol. Therefore, comparing the specific gravity of the beverage, the final specific gravity is subtracted from the first to give the molecular weight of C0 2 that left the vessel.

Journal of Food Science Technology.

Properties of Sorghum grain and new development of possible significance to the brewing industry. Fermented beverages Revolvy Brain revolvybrain. Effects of malting on proximate composition and in vitro protein and starch digestibility of Sorghum grain. It contains vitamins, iron, manganese, magnesium, phosphorus and calcium and also contains about Sorghum based foods includes burukutu, pito, bogobe, kisra, injera etc.

An alcoholic drink is a drink that contains ethanol, commonly known as alcohol.
