What characteristic of comb honey can be impacted by travel stains?

Travel stains primarily affect the appearance of comb honey rather than its sensory qualities. When honey is transported, especially over long distances, it can pick up dirt, dust, or other contaminants that create visible marks or discolorations on the comb. These stains can change the visual impression of the honey, leading to a perception of decreased quality or marketability.

While flavor, texture, and aroma may also be components of honey's overall quality, they are less likely to be directly impacted by the travel conditions and handling that cause travel stains. The honey itself, when handled properly, retains its inherent flavors, textures, and aromas regardless of the external appearance caused by travel-related issues. Thus, color stands out as the characteristic most significantly influenced by travel stains.
