Description
CAP preserves aroma by reducing O₂ and elevating CO₂ at low temperatures to limit oxidation of volatile compounds.
Technical
In CAP, low O₂ (<1 %) suppresses oxidative enzymes and radical formation, while CO₂ acts as a physical solvent, increasing the solubility of aromatic volatiles in the headspace and reducing their loss. The combined effect slows the conversion of aldehydes, ketones, and terpenes into off‑odors, thereby extending sensory quality.
