Abstract: In order to study the stability of anthocyanin in blue hazelnut,the anthocyanin was extracted by an ultrasonic-assisted method,and the effects of different temperature,pH,ascorbic acid and different metal ions on the stability of anthocyanin were studied with the retention rate as the detection index.The results showed that the preservation at 4 ℃or room temperature was the best.The preservation of the weak acid environment was effective in maintaining stability.The proper amount of ascorbic acid helped to maintain the stability of anthocyanins in blue hazelnut.The effects of Na+,Ca2+ and Mg2+ metal ions are not significant,and K+,Ba+,Cu2+ and Fe3+ metal ions have a great influence on them.Therefore,in the preparation and application of anthocyanins extracted from blue hazelnut fruits,they should be extracted at a lower temperature and in a weak acid environment,and an appropriate amount of ascorbic acid should be added to avoid contact with copper and iron containers during storage.
