Fish provides a rich source of protein and omega-3 fatty acids. Eggs are a versatile food source, and dairy products include milk, cheese, and yogurt.
4. How are microorganisms used in food production? |
|
Ans. Microorganisms play a crucial role in food production. Bacteria are used for the fermentation of various foods and beverages like yogurt, cheese, and sauerkraut. Yeast is used in the fermentation process for bread, beer, and wine production. These microorganisms break down complex molecules, resulting in the transformation of raw ingredients into edible and flavorful products.
5. What are some examples of processed foods? |
|
