Progress on Anthocyanidin Nano-carriers

Anthocyanidin is a kind of flavonoid water-soluble natural pigment,which has the physiological activities of antioxidation,anticancer,anti-inflammatory,antibacterial,hypoglycemic and so on. However,in the process of processing and storage,the stability of anthocyanidin to different environmental conditions is low,and it is easy to degrade. Nano-carriers made of lipids,polysaccharides and proteins have good biocompatibility,biodegradability and non-toxicity,which can significantly improve the stability,biological activity and bioavailability of anthocyanidin. In this paper,the preparation technology and the applications in improving the physical and chemical stability of anthocyanidin of anthocyanidin-loaded nano-liposomes,biomacromolecule nano-carriers and nano-emulsions in recent years are reviewed,and the developing trend of anthocyanidin nano-carriers in the future is prospected.
