Refrigeration slows which aspects of foods?

• A. Chemical and biological processes
• B. Only chemical processes
• C. Only biological processes
• D. Flavor development

Answer: (A)

Refrigeration slows both chemical reactions and biological activity in foods. At low temperatures, enzymes work more slowly and microbes take longer to grow, so spoilage, fermentation, and decay happen much more slowly. It also slows chemical changes like oxidation and enzymatic browning that affect flavor, color, and texture. Since flavor development comes from these chemical and biological processes, it is slowed as well, but the underlying reason is that both types of changes are slowed by cold storage. The best description is that refrigeration slows chemical and biological processes. The other options isolate only one category or point to flavor as a separate process, which doesn’t capture the full range of changes refrigeration affects.
