What You Need to Know
Mechanical shear forces disperse hydrophilic pepper solids (containing capsaicin and capsanthin) into a continuous oil phase, with spice particulates acting as natural emulsifiers through phospholipid content. The Maillard reaction products from roasted peppers enhance emulsion stability.
Creates a shelf-stable, intensely flavored paste where oil carries fat-soluble aromatics while evenly distributing heat perception.
