Sugar can act as a plasticizer, potentially increasing the mobility of flavor molecules and making them more available for release upon consumption. Exposure to light, oxygen, and heat can oxidize terpenes, leading to the formation of aldehydes that introduce rancid or stale notes.

Antioxidant-rich essential oils, or the addition of natural tocopherols, can help slow this oxidative decline. Analytical Validation and Quality Control Relying on sensory panels alone is insufficient for maintaining consistency in commercial baking.
Gas chromatography-olfactometry (GC-O) is a powerful tool that links chemical data with human perception, identifying which specific terpenes are contributing positively and which may be diminishing. By establishing a baseline "fingerprint" for the ideal flavor profile, manufacturers can monitor each batch to confirm that the essential oils are performing as expected.

Understanding how these volatile compounds behave under heat and during shelf life is critical for formulators aiming to deliver a consistent aromatic experience. Adding essential oils late in the dough mixing stage minimizes the time they are exposed to shear and heat, reducing premature evaporation.
