Food Technology Year 11 Exam Quiz
with Complete Solutions
How do preservatives help extend the shelf life of food?
✔✔Preservatives prevent the growth of bacteria, mold, and yeast, slowing down spoilage and
maintaining the food’s quality.
Why is food labeling important for consumers?
✔✔Food labeling provides essential information such as ingredients, nutritional content,
allergens, and expiry dates, helping consumers make informed choices.
What is the role of vitamins in food?
✔✔Vitamins are essential for various bodily functions such as immune support, bone health, and
energy metabolism.
How does freezing preserve food?
✔✔Freezing slows down the activity of enzymes and microorganisms, which helps to maintain
the food's nutritional value and quality.
1
,What is the function of fats in food production?
✔✔Fats provide energy, help with the absorption of fat-soluble vitamins, and contribute to the
texture and flavor of food.
What is the difference between saturated and unsaturated fats?
✔✔Saturated fats are solid at room temperature and can raise cholesterol levels, while
unsaturated fats are liquid at room temperature and are considered healthier for the heart.
How does the process of pasteurization work to preserve food?
✔✔Pasteurization involves heating food to a specific temperature for a short period to kill
harmful bacteria and extend shelf life without compromising nutritional value.
What are the advantages of organic farming in food production?
✔✔Organic farming avoids synthetic pesticides and fertilizers, promoting biodiversity,
improving soil health, and reducing chemical exposure in food.
How do enzymes contribute to food processing?
✔✔Enzymes speed up chemical reactions, breaking down food molecules to improve texture,
flavor, and overall quality in products like cheese and bread.
2
, Why is it important to store food at the correct temperature?
✔✔Proper food storage prevents the growth of harmful microorganisms, reduces spoilage, and
helps maintain the nutritional value and flavor of food.
What is the purpose of emulsifiers in food products?
✔✔Emulsifiers help mix ingredients that would normally separate, like oil and water, and
improve the texture and stability of products like mayonnaise and salad dressings.
How does dehydration preserve food?
✔✔Dehydration removes moisture, which inhibits the growth of bacteria and fungi, thus
extending the shelf life of foods like fruits, meats, and vegetables.
What are the main types of food packaging used for preservation?
✔✔Common types of food packaging include vacuum-sealed, plastic wraps, cans, glass jars, and
tetra packs, each designed to protect food from contamination and spoilage.
What is the difference between food fortification and food enrichment?
