Description
Vacuum‑assisted infusion extracts aromatic compounds from herbs at low temperatures, preserving volatile terpenes and accelerating flavor penetration into protein substrates.
Technical
By reducing the ambient pressure to 50–80 mmHg, the boiling points of solvent–herb mixtures drop, allowing extraction at 30–45 °C. This mild temperature regime preserves heat‑labile terpenes and flavonoids while minimizing thermal degradation of alkaloids. Precise pressure control is essential to avoid over‑extraction and contamination.
