What You Need to Know
The process typically involves spray‑drying or extrusion to form nano‑sized particles (50–200 nm) with a shell of maltodextrin, gum arabic, or whey protein isolate. The shell stabilizes the core during heating up to 120 °C and releases the active compounds when environmental triggers such as a pH shift from 5.5 to 7.0 occur.
