Microbes in Industrial Products - Fermented Beverages
Covers the large-scale production of alcoholic beverages such as wine, beer, whisky, brandy, and rum using yeast.
What is Microbes in Industrial Products - Fermented Beverages?
An anaerobic metabolic process that converts sugar to acids, gases, or alcohol, carried out by yeast and bacteria.
Key points
- Identify the role of yeast in producing alcoholic beverages.
- Differentiate between fermented and distilled beverages.
- Explain the basic steps involved in the production of wine, beer, and spirits.
- Recognize the importance of controlled conditions in industrial fermentation.
Common exam trap
Confusing fermentation with distillation.
Definitions
- Term
Fermentation
- Meaning
An anaerobic metabolic process that converts sugar to acids, gases, or alcohol, carried out by yeast and bacteria.
- Term
Distillation
- Meaning
A process of separating components or substances from a liquid mixture by selective boiling and condensation.
- Term
Ethanol
- Meaning
A volatile, flammable, colourless liquid which is the intoxicating constituent of wine, beer, spirits and other alcoholic drinks, produced by the fermentation of sugars and starches.
- Term
Malt
- Meaning
Barley or other grain that has been steeped, germinated, and dried, used in brewing and distilling.
