摘要: 为研究蓝靛果中花青素的稳定性,采用超声波辅助法对蓝靛果中花青素进行提取,以保留率作为检测指标,研究不同温度、pH值、抗坏血酸及不同金属离子对花青素稳定性的影响。结果表明:花青素在4 ℃或室温下保存稳定性最好;花青素在弱酸条件下性质较稳定;加入适量抗坏血酸有助于维持花青素的稳定性; Na+、Ca2+、Mg2+对花青素稳定性的影响较小,K+、Ba+、Cu2+、Fe3+对花青素稳定性的影响较大。因此,从蓝靛果中提取花青素在制备和应用中,应于较低温度、弱酸环境进行,并添加适量的抗坏血酸,保存时避免与铜铁容器接触。

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.

Key words: Blue hazelnut, Anthocyanins, Metal ion, Stability, Temperature
