Which one of the following is not a method of food preservation?

  • A.Salting
  • B.Drying
  • C.Boiling
  • D.Pickling

Answer: C

Correct answer: Boiling

Boiling kills the organisms present at the time but leaves the food just as open to recontamination as before, so it preserves nothing by itself. Salting and drying remove the water microbes need, and pickling makes the food too acid for them - each creates conditions in which spoilage organisms cannot grow.
