摘要
对红酵母虾NZ-01青素(以下简称虾青素)的生物学特性进行研究。分别利用硫氰酸铁法及邻二氮菲Fe氧化法检测虾青素的抗氧化性,并从光、温度、pH值和金属离子方面检测其稳定性。结果表明,虾青素有较强的抗氧化性,自然光照、高温、强酸、强碱会对虾青素的稳定性造成不同程度的破坏,Na+、K+、Ca2+、Li2+对虾青素略有增色效应,Mg2+、Zn2+、Co2+对虾青素无明显影响,Ba2+、Mn2+、Fe2+、Cu2+对虾青素破坏作用较为明显,该虾青素具有较好的应用前景。
The biological characteristics of astaxanthin from Rhodozyma NZ-01 was studied.The antioxidant activity of astaxanthin were measured by ferric thiocyanate-nitric acid catalytic kinetic and o-phenanthroline-Fe2＋ oxidation method.Its stability was examined based on light,temperatrue,pH value and several metal ions.The results showed that the astaxanthin had strong antioxidant activity and visible light,high temperature,strong acid or alkali had different damaging effects on its stability.Mg2＋,Zn2＋ and Co2＋ had little hyperchromic effect on it,while Na＋,K＋,Ca2＋ and Li2＋ had no effect,Ba2＋,Mn2＋,Fe2＋ and Cu2＋ could destroy the astaxanthin obviously.These indicated that this kind of astaxanthin had good application prospects.
