摘要
花青素的稳定性易受加工条件的影响,为提高花青素在果蔬深加工过程中的稳定性,以软枣猕猴桃为试材,对其花青素进行提取,比较光照、pH值、温度及金属离子对花青素保存率的影响。结果表明:避光处理是软枣猕猴桃花青素加工过程保持稳定性的有效方法;pH值3.0、温度25℃时花青素稳定性始终保持在较高水平;K^+、Na^+、Ca^2+对保持花青素的稳定性显著优于Mg^2+、Cu^2+。
The stability of anthocyanins is easily affected by processing conditions. In order to improve the stability of anthocyanins during deep processing of fruits and vegetables, the effects of different processing factors on the preservation rate of anthocyanins in Actinidia arguta were compared. Taking A. arguta as the research material, anthocyanins in A. arguta were extracted, and the effects of light, pH, temperature and metal ions on the preservation rate of anthocyanins were compared. The results showed that avoiding light was an effective method to keep anthocyanin stability during processing;anthocyanin was more stable at pH 3.0 and temperature 25℃;K^+、Na^+、Ca^2+ had better effects in maintaining anthocyanin stable than that of Mg^2+、Cu^2+.
