What is the meaning of overrun in the context of food preparation?

In the context of food preparation, overrun refers to the amount of air that is incorporated into a mixture, particularly in products like ice cream or whipped cream. This incorporation of air affects the texture, volume, and overall lightness of the finished product. A higher overrun typically results in a lighter and fluffier texture, which is desirable in many food applications. The measurement of overrun is essential because it can influence both the quality and the perception of richness in the final dish.

The other options, while they may relate to concepts in food preparation, do not accurately define overrun. The mixture or incorporation of air into a food item is what distinguishes overrun as a specific term used in culinary contexts.
