Study Notes
Fermentation Types
- Fermentation is a metabolic process that converts sugars to acids, gases, or alcohol.
- It's a crucial process in various industries, like food and beverage production.
- Three significant types of fermentation used industrially are:
Lactate Fermentation
- Involves the conversion of sugars (e.g., glucose) into lactic acid.
- This process is anaerobic (occurs without oxygen).
- Bacteria, such as Lactobacillus species, play a primary role in this type of fermentation.
- Common examples of products using lactate fermentation include yogurt, sauerkraut, and kimchi.
- Lactic acid contributes to the sour taste and preservation of these food products.
- Lactic acid bacteria (LAB) are used to generate the beneficial effects in food production.
Ethanol Fermentation
- Consists of converting sugars into ethanol and carbon dioxide.
- Also an anaerobic process.
- Yeast, particularly Saccharomyces cerevisiae, are the primary agents in this type of fermentation.
- This type of fermentation is crucial for alcoholic beverage production, like wine, beer, and spirits.
- The ethanol produced contributes to the alcoholic content and flavor profiles of these beverages.
Acetic Acid Fermentation
- Involves the conversion of ethanol to acetic acid.
- Aerobic process (requires oxygen).
- Acetobacter bacteria are the primary agents in this type of fermentation.
- Key to the production of vinegar.
- Acetic acid gives vinegar its characteristic sour taste and antimicrobial properties.
