Abstract: Anthocyanins has a high health benefits and biological activity, which can make the solution easily absorbed and has a bright color, beautiful appearance in oral liquid. However, due to its particularity antioxidant activity, it is easy to be affected by the external physical and chemical factors, and then oxidation, polymerization, degradation and other unstable phenomena occurs that seriously affect the stability of products and shelf life. The traditional methods of pH regulation, deoxygenation and light avoidance could not meet the demand of stable anthocyanins. Addition of stabilizer to anthocyanins is a new effective way to improve the stability of anthocyanins. This paper is prepared to summarize systematically the principle and application methods of anthocyanins stabilizers to explore the key technology of clarification and stabilization of traditional Chinese medicine in the natural oral liquid, which may provide theoretical support and technical reference for the development and utilization of anthocyanins stabilizer.
