摘要: 采用微生物法提取千日红花色苷,研究了菌种、温度、pH值、固液比和处理时间对提取效果的影响,并探讨了在光照、酸度、氧化剂、还原剂、温度、糖及金属离子存在的条件下花色苷的其稳定性。结果表明,在可见光范围内千日红花色苷的最佳吸收波长为530nm,黑曲霉(Aspergillus niger)的提取效果优于康氏木霉(Trichoderma viride)、绿色木霉(Trichoderma koningi Oud.)。在花色苷稳定性研究中发现,光照、氧化剂、高温、Fe2+、Fe3+和Al3+存在的条件不利于花色苷的稳定,而在有还原剂存在的条件下,花色苷的稳定性增强。酸性或中性环境中,花色苷较稳定。糖、Zn2+和Ca2+对稳定性基本没有显著影响。

Abstract: The extraction of anthocyanin in gomphrena globosa by microorganism was studied. The effects of microorganism, temperature, pH value, ratio of solid to liquid and treatment time on the extract of anthocyanin in gomphrena globosa wasinvestigated, and the result was estimated by color value measured by extinction photometry method. The stability of anthocyanin was also studied in the term of sunlight, acidity, oxidant, reducer, temperature, sugar or metal iron, respectively. The results showed that, the premium absorbed wavelength is 530 nm; the extraction of anthocyanin was more influenced by Aspergillus niger than Trichoderma viride and Trichoderma koningi Oud; the stability of anthocyanin was researched in the term of sunlight, oxidant, high temperature, Fe2+, Fe3+ or Al3+, whereas it is improved in the acid environment or reducer existing; it is hardly affected of the stability of anthocyanin by sugar, Zn2+ or Ca2+.
