What You Need to Know
Shear forces from granite disrupt cellulose matrices, releasing bound volatiles like linalool in coriander. Frictional heat (40-50°C) accelerates alliinase conversion in garlic. Coconut's lipid globules emulsify with released water.
Creates cohesive pastes where particle size distribution (50-200μm) optimizes mouth-coating without grittiness, unlike blade-chopped versions.
