Question 13: Explain the scientific process of fermentation in local food production. In your answer, include: - What fermentation is - The microorganisms involved - Why fermentation is important in food production - One (1) example from a local food

Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol in the absence of oxygen.

• What fermentation is: It is an anaerobic biochemical process where microorganisms like bacteria and yeast break down complex organic compounds (typically carbohydrates) into simpler substances, releasing energy.
• The microorganisms involved: The primary microorganisms involved in food fermentation are bacteria (e.g., lactic acid bacteria) and yeast (e.g., Saccharomyces cerevisiae). These microbes possess enzymes that catalyze the breakdown of sugars.
• Why fermentation is important in food production: Fermentation is crucial for several reasons: it preserves food by producing acids or alcohol that inhibit spoilage organisms, enhances flavor and aroma, improves nutritional value by increasing vitamin content or making nutrients more bioavailable, and creates unique textures.
• One (1) example from a local food: In the production of gari, fermentation of grated cassava pulp by lactic acid bacteria (e.g., Lactobacillus species) breaks down cyanogenic glycosides, reducing toxicity, and produces lactic acid, which gives gari its characteristic sour taste and acts as a preservative.
