摘要: 本文主要研究了火棘色素在不同环境下的稳定性,实验结果表明:天然火棘色素颜色鲜亮,在溶液酸度为pH3左右时对光较稳定,在温度低于90℃火棘色素基本上是稳定的,此外大多数的金属离子对其无影响,但是对Cu2+、Fe3+较敏感。此外防腐剂对火棘色素的稳定性影响不显著,而碳水化合物可以增强火棘色素的稳定性。

Abstract: In this paper, the effects of different factors on the stability of Pyracantha fortunena pigment were studied. The results were as follows; the natural Pyracantha fortunena pigment was brillant, insensitive to light at pH3 and stable when the temperature was less than 90℃. At the same time, the influence of the minerals and preservative was, but the presence of Cu2+、Fe3+ that could lead to its loss, and Pyracantha fortunena pigment was enhanced when saccharides were applied to its solutions.

Key words:  Pyracantha fortunena pigment, conditions, stability
