What You Need to Know
Spray‑drying with a maltodextrin carrier forms a porous matrix that entraps aroma compounds; the matrix collapses when heated to 70–80 °C, releasing the volatiles. Moisture below 5 % and shear rates under 2000 rpm preserve capsule integrity, while exposure to high humidity or temperatures above 100 °C degrades sensitive molecules and generates off‑odors.
The Science
Primary Reaction
Dehydration and matrix formation during spray‑drying encapsulates volatile aroma compounds
