Which temperature range defines refrigeration in cold preservation?

Explanation:
Keeping foods in refrigeration means using temperatures that slow bacterial growth without freezing them. The targeted range for refrigeration is about 32°F to 40°F (0°C to 4°C). The range 34°F–40°F fits squarely in this zone, providing enough chill to slow spoilage and keep quality without freezing. Warmer ranges like 50–60°F or 60–70°F allow bacteria to multiply more quickly, increasing the risk of foodborne illness. Freezing occurs at about 0°F–10°F, which is not refrigeration and changes texture and moisture in foods.
