摘要
以野生毛葡萄皮渣为原料,用乙醇提取花色苷并研究其稳定性。结果表明:毛葡萄皮渣花色苷对p H、温度、光照、氧化剂、还原剂和防腐剂敏感;葡萄糖、果糖、蔗糖对该花色苷有一定的护色作用;金属离子K^+、Na^+、Mg^(2+)、Zn^(2+)对毛葡萄皮花色苷影响较小,Fe^(3+)、Cu^(2+)对该花色苷有明显的破坏作用。
Wild V. quinquangularis Rehd. grape peel was used as the raw material to extract anthocyanins by ethanol solution. The results showed that the anthocyanins was sensitive to p H, temperature, light, oxidant, reducer and preservative. Glucose, fructose and sucrose had protective function to the anthocyanins in some extent. K+, Na+, Mg2+, Zn2+ exhibited a little effect. In contrast, Cu2+ and Fe3+ contributed obvious adverse effects on stability of the anthocyanins.
