PURPOSE: A novel composite using anthocyanine and anionic polysaccharides is provided to prevent decomposition by anthocyanine hydration and to enhance structural stabilty of anthocyanine. CONSTITUTION: An anthocyanine-polysaccharide composite contains anthocyanine and anionic polysaccharides which are combined by ion bond. The anionic polysaccharide contains sulfate group or carboxy group. The anionic polysaccharide is hyaluronic acid, o-sulfated hyaluronic acid, dextran sulfate, chondroitin sulfate, dermatan sulfate, keratin sulfate, heparin, heparin sulfate, alginic acid, a mixture thereof, or complex thereof. The composite additioinally contains biocompatible or biodegradable carriers. The carrier is a liposome, micelle, or neutralized vesicle. A pharmaceutical, cosmetic, or food composition contains the composite.
