摘　　要：研究了蜂胶水溶性黄酮醇类化合物在不同条件下的稳定性,结果表明,在低温和pH>6条件下产品较为稳定,Sn2+、Cu2+以及光照对其吸光度影响明显,Fe3+、Al3+以及几种常用的食品添加剂影响甚微,该产品具有较好的耐氧化性和耐还原性,β-环糊精对产品具有保护作用,可提高其热稳定性。In this paper, the stability of water-soluble flavonol is studied in different conditions. The results show that the watersoluble flavonol is relatively stable under the low temperature and in the range of pH〉6. Sn^2＋, Cu^2＋ and light affect it obviously on its light absorbency, but Fe^3＋, Al^3＋ 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.
