| 摘 要： | 采用化学动力学方法研究pH值、温度、光照、初始质量浓度对西红花苷-1稳定性的影响。结果表明:西红花苷-1在溶液中的降解反应为表观一级反应,pH值、温度、光照、初始质量浓度均能够影响其稳定性,在pH6.0～7.0之间时最稳定,在自然光照射下的反应速率较紫外光更快,对温度极其敏感,但反应速率常数与其初始反应质量浓度无关,其在溶液中降解反应活化能Ea为45.36kJ/mol。

| Abstract: | The effects of pH,temperature,sunlight,UV light and initial concentration on the stability of crocin-1 were studied by chemical kinetics.The results suggested the degradation reaction of crocin-1 in solution could be fitted by pseudo-first-order reaction.The stability of crocin-1 was effect by pH,temperature,sunlight,UV light and initial concentration.Crocin-1 was sensitive to temperature,and is prone to degradation.The activation energy of croin-1 in solution was 45.36 kJ/mol. |
