What You Need to Know
Smoke-derived phenolic compounds such as guaiacol, phenol, cresol, syringol, and 4‑methylguaiacol are extracted at 200–300 °C and adsorbed onto carriers (e.g., maltodextrin, whey protein isolate, cyclodextrin) via fluidized‑bed or spray‑drying. The process preserves volatile aromatics by maintaining inlet temperatures of 120–150 °C and outlet temperatures below 80 °C, achieving ~90 % loading efficiency while preventing thermal loss of phenolics.
