Food Tech GCSE- Dairy Questions and Answers Already Passed How does the fat content in milk affect its texture and flavor? Higher fat content in milk contributes to a creamier texture and richer flavor, while lower fat content results in a lighter, less creamy taste. What is the role of rennet in cheese making? Rennet is an enzyme used to coagulate milk, causing it to separate into curds and whey, which is the first step in cheese production. Why is homogenization important for milk? Homogenization is the process of breaking down fat molecules in milk to create a smooth, consistent texture, preventing the cream from separating. What is the difference between full-fat milk and skim milk? Full-fat milk contains all the natural fat found in milk, while skim milk has most or all of the fat removed, making it lower in calories. 2 How does the fermentation process work in yogurt production? Fermentation involves adding beneficial bacteria to milk, which convert lactose into lactic acid, thickening the milk and giving yogurt its tangy flavor. What are the benefits of consuming dairy products as part of a balanced diet? Dairy products provide essential nutrients like calcium, vitamin D, and protein, which are important for bone health, muscle function, and overall nutrition. How does cheese differ from milk in terms of nutritional content? Cheese is richer in fat and protein compared to milk, as it is made by concentrating the curds. It also has a higher concentration of calcium. Why is it important to store dairy products at the correct temperature? Storing dairy products at the correct temperature (usually below 5°C) prevents bacterial growth, spoilage, and maintains product quality and safety. What is the role of lactose in milk, and how does it affect people with lactose intolerance? Lactose is the natural sugar in milk. People with lactose intolerance lack the enzyme lactase, making it difficult for them to digest lactose, leading to digestive discomfort. 3 What is the process of making butter from cream? Butter is made by churning cream, which separates the butterfat from the buttermilk. The butterfat is then kneaded to remove excess liquid and form a solid product. What are some common methods of dairy preservation? Common methods include pasteurization, refrigeration, freezing, and drying, all of which help extend shelf life and prevent spoilage of dairy products. How is cream separated from milk? Cream is separated from milk through the process of centrifugation, where milk is spun rapidly to separate the lighter cream from the heavier milk. Why is the protein casein important in cheese making? Casein is the primary protein in milk that coagulates during cheese making, forming the curds that become cheese. What is the difference between soft cheese and hard cheese?
