Abstract: In this paper, the stability of water-soluble flavonol is studied in different conditions. The results show that the water- soluble flavonol is relatively stable under the low temperature and in the range of pH>6. Sn2+, Cu2+ and light affect it obviously on its light absorbency, but Fe3+, Al3+ and some food additives affect it little. The water-soluble flavonol has relatively good antioxidant property and anti-reduction. β-cyclodextrin can improve the heat stability of the water-soluble flavonol.
