Research on Stability of Water-soluble Flavonoids of Orange Peel

This article studied the stability of water-soluble flavonoid compound in different condition. The results showed that the water-soluble flavones compound is more stable in the range of 5≤pH≤7 and in the presence of carbohydrates. The natural light could lead to certain degree of decomposition while K+, Na+, Al 3+ , Zn 2+ contribute to the stability of the product. The stability is also affected by the following compounds: Mg 2+ ,Fe 3+ having significant effects, reducing agent 2% Vc and oxidizing agent 2% H 2O 2 having no influence, Na 2SO 3 having remarkable influence on the flavones compound.
