Food preservation is defined as which of the following?

• A. A method to cook foods rapidly
• B. A process that uses dehydration only
• C. Can make food last longer without spoiling
• D. A method to flavor foods

Answer: (C)

Food preservation is about extending how long food stays safe and edible by slowing or stopping spoilage. The correct statement captures this goal by saying it can make food last longer without spoiling. Preservation isn’t just cooking quickly, since rapid cooking may kill some microbes but doesn’t ensure the food remains safe or edible for an extended period. It isn’t limited to dehydration, either—that’s one technique among many that reduces spoilage, but preservation as a concept covers various methods like cooling, freezing, canning, fermenting, salting, and adding preservatives. And it isn’t about flavoring food; flavoring changes taste, not necessarily the shelf life or safety.
