What is the sterilization process?

• A. It uses low heat for a short time to preserve texture.
• B. It pasteurizes food without destroying heat-tolerant organisms.
• C. It destroys all microorganisms by heating to a high enough temperature for a long enough time, though quality may decline.
• D. It seals foods in cans to prevent contamination.

Answer: (C)

Sterilization is a heat treatment that aims to kill every microorganism, including spores, by heating to a high enough temperature for a long enough time. Because it targets all life forms that could cause spoilage or illness, it can significantly affect quality, texture, flavor, and nutrients.

This is why the option describing all microorganisms being destroyed by heat at a high temperature for a sufficient time, even if quality may decline, is the best fit. The other descriptions refer to processes that do not achieve complete sterilization: low heat for a short time to preserve texture aligns with pasteurization or blanching, which does not eliminate all microbes; pasteurization that doesn’t destroy heat-tolerant organisms is not sterilization; and sealing in cans is a packaging step, not the sterilization itself.
