Which is an application of nanotechnology in the foodservice industry?

• A. Computer software that manages inventory via the tracking of sales
• B. Foodservice storage containers that are permeable to gases that contribute to spoilage
• C. A frying oil that catalytically inhibits the thermal polymerization of the oil
• D. Increasing the concentration of vitamin D in low-fat dairy products to increase the potential for absorption

Answer: (C)

Nanotechnology in foodservice often focuses on adding nano-scale materials that directly influence chemical reactions and stability of foods during processing. The scenario described—oil that contains a nano-scale catalyst to inhibit the thermal polymerization of the oil during frying—fits this idea perfectly. When oil is heated for frying, it can undergo polymerization, forming deposits, dark colors, off-flavors, and reduced quality. Introducing nano-scale catalysts or stabilizers can steer or slow these reactions at the molecular level, effectively extending oil life and maintaining quality by reducing polymer formation.

The other examples don’t showcase this nano-enabled approach: software-based inventory management is information technology rather than a nanoscale food processing solution; packaging that is permeable to spoilage-causing gases is more about material properties at a macro level and would generally be undesirable; fortifying dairy with additional vitamin D is nutritional enhancement, not a nano-driven intervention.
