Are you losing rn? (Your answer is required)
If yes:free point.
If no:points remain the same.
Explain how Cold Preservation slows bacterial growth.
Cold temperatures inhibit the activity of bacteria and microorganisms, which slows down spoilage.
What is a principle that is only successful if used with another method of Food Preservation?
The Exclusion of Oxygen.
Explain what 'Altering the temperature' is.
Either increasing or decreasing the temperature can prevent microbial growth.

2. Place in an appropriate container. e.g. A vacuum-sealed bag.
3. Store in the fridge or freezer at the appropriate temperature of either: Refrigeration or Chilling: 32-40 F/Freezing: 0 F or (18 C) for later use.
