A food described as shelf-stable is one that

  • A.requires refrigeration throughout its life
  • B.keeps at room temperature without spoiling
  • C.must be kept frozen until the day of use
  • D.has to be eaten within a day of opening

Answer: B

Correct answer: keeps at room temperature without spoiling

A shelf-stable food has been made safe by processing and formulation together - canning, low water activity, high acidity, or a combination - so no chill chain is required until the pack is opened. Once opened, the barrier is broken and most such foods need refrigerating like any other.
