| 摘要: |
| 本文对红汁乳菇色素的稳定性进行了系统研究,结果表明:红汁乳菇色素紫外光谱最大吸收波长为251nm,且为单一吸收峰;在碱性条件下能稳定存在,在酸性条件下随酸度增大吸光度减小,颜色变浅,稳定性较差;对自然光比较敏感,耐热性差;色素对Fe3+较为敏感,而Na+、K+、Ca2+、Zn2+、Al3+、Mg2+、Cu2+对色素无不良影响;色素耐氧化、还原能力较好;加入淀粉会使色素增色,而葡萄糖、蔗糖、柠檬酸对色素影响甚微. |

| Study on Pigment Stability of Hathudake |
|
|
| Abstract: |
| The pigment stability of Hathudake has been studied. The results showed that λmax was 251nm. It could be stabilized between pH 8-14. It had weak stability of light and heat. Its color was changed by Fe 3+ , but the pigment was not harmfully affected by Na + , K + , Ca 2+ , Zn 2+ , Al 3+ , Mg 2+ , Cu 2+ . It was resistant to oxidation and reduction. Its color could be increased by adding starch, but not by adding glucose, citric acid and sucrose. |
