3.6.2.1.1 Primary processing of raw food materials Quiz: AQA Food Preparation and Nutrition, Unit 5

The 20 questions

1. Which process is an example of primary processing of wheat?

   • Fermenting flour with a sourdough starter for a long time
   • Baking flour into a loaf of bread for sale
   • Milling wheat grain into flour
   • Shaping pasta dough by hand into short shapes

2. What is the purpose of cleaning raw food materials during primary processing?

   • To add flavour to the raw material before it is sold
   • To package the raw material ready for sale in the shop
   • To cook the raw material slightly before it is sold
   • To remove dirt, debris and unwanted matter from the raw material

3. Which milk treatment uses a high heat for a very short time to give a long shelf life without refrigeration?

   • Storing raw milk fresh in a fridge without any treatment at all
   • Pasteurisation at a low temperature for a long period
   • Micro-filtration, which removes bacteria through a fine filter without heat
   • UHT treatment, which heats milk to a very high temperature briefly

4. Which milk treatment uses heat to kill harmful bacteria while keeping the milk fresh for a short time?

   • Pasteurisation, which uses a controlled heat treatment
   • Homogenisation alone, which breaks up the fat globules in the milk
   • Sterilisation in a sealed container at a high temperature
   • Micro-filtration only, which uses a fine filter and no heat

5. Which milk treatment removes bacteria by passing the milk through a fine filter instead of heating it?

   • Sterilisation, which heats milk in a sealed container
   • Pasteurisation, which heats milk to a controlled temperature
   • UHT treatment, which heats milk to a very high temperature
   • Micro-filtration, which uses a fine filter

6. What is the main difference between pasteurised and sterilised milk?

   • Pasteurised milk contains no protein and sterilised milk contains protein
   • Sterilised milk is heated for longer in its container, giving a longer shelf life
   • Sterilised milk is never heated at any stage of its processing
   • Pasteurised milk is always sold in glass bottles while sterilised milk is sold in cartons

7. Which primary processing step applies to fish?

   • Cleaning and gutting the fish after it has been caught
   • Smoking the fish over oak chips for several hours
   • Baking the fish into a pie for a family meal
   • Seasoning the fish with herbs and spices before cooking

8. Which step is primary processing for fruit?

   • Freezing the fruit into packs for a freezer section
   • Harvesting and washing the fruit before it is sold
   • Making the fruit into a jam with sugar and pectin
   • Adding sugar to the fruit to make a dessert

9. Which process is part of the primary processing of meat from livestock?

   • Rearing and slaughtering the animal before cutting the meat
   • Marinating chicken in spices and oil for a barbecue
   • Smoking bacon over wood chips for a rich flavour
   • Making a sausage from minced pork with seasoning

10. Which of these is a primary processed milk product?

    • Cheddar cheese, which is made by curdling milk
    • Natural yoghurt, which is made by fermenting milk
    • Butter, which is made by churning cream
    • Pasteurised milk, which has been heat treated

11. Why is primary processing important for food safety?

    • It removes the need for any storage of the materials
    • It makes raw materials more expensive for the buyer to purchase
    • It adds flavour to the raw materials before they are used
    • It removes contaminants and makes raw materials safe to use

12. Which example describes harvesting in primary processing?

    • Blending the grain into a smoothie for breakfast
    • Storing the grain in a bag in the store cupboard
    • Gathering ripe wheat from the fields at the right time
    • Baking the wheat into a loaf for sale in the shop

13. Which statement about heat treatment of milk is accurate?

    • Heat treatment has no effect on the bacteria that can be present in milk
    • Heat treatment turns milk into cheese directly without any other step
    • Heat treatment changes how long milk stays fresh and whether it is safe to drink
    • Heat treatment only changes the colour of the milk in the bottle

14. A miller removes the outer husk from wheat before grinding it. Which stage of processing is this?

    • Preservation with additives
    • Secondary processing
    • Primary processing
    • Fortification

15. Why is milk usually heat treated after it is collected from the farm?

    • To add extra fat to the milk for a richer taste
    • To remove the lactose from the milk for everyone who drinks it
    • To kill harmful bacteria and make it safe to drink
    • To make the milk thick enough to set as cheese

16. Which of these is still a raw, unprocessed food rather than a product of processing?

    • Wholemeal flour milled from grain
    • Pasteurised milk in a bottle
    • Sterilised milk in a sealed carton
    • Harvested wheat ears

17. Which process is applied to remove the outer husk from a grain of rice before it can be eaten?

    • Primary processing, such as hulling
    • Secondary processing into a rice pudding
    • Fortification with added vitamins and minerals
    • Emulsification with oil and water

18. Which step is needed to clean raw fish before it can be sold?

    • Adding flavourings to the fish for the counter
    • Coating the fish in breadcrumbs for frying
    • Removing scales and guts from the fish
    • Packing the fish in a tray with a label

19. Which milk process keeps milk fresh for a short period in a fridge after heating?

    • Sterilisation in a sealed bottle for long storage
    • Micro-filtration, which keeps milk for months at room temperature
    • UHT treatment, which keeps milk for many months
    • Pasteurisation, which uses a controlled heat treatment

20. Which of these is a stage of primary processing for cereals?

    • Baking the grain into a cake for dessert
    • Coating the grain in sugar for a sweet snack
    • Mixing the grain with milk for a breakfast cereal
