摘要: 研究了EDTA和β-CD对唐古特白刺果实红色素稳定性的影响。结果表明:Fe3+对唐古特白刺果实红色素有明显的不良影响;加入EDTA、β-CD不仅可减缓唐古特白刺果实红色素的褪色速度,还可有效地抑制色素因Fe3+而对其产生的影响。实验结果还表明:EDTA对含Fe3+色素的护色作用均优于β-CD,增强了色素的稳定性,使之扩大了应用范围,提高使用价值。

关键词: 唐古特白刺果实, 红色素, Fe3+, 稳定性, EDTA, &beta, -CD

Abstract: This paper studied the effects of EDTA and β-CD on the stability of red pigment from Nitraria tangutorun Bobr. fruit. The results showed that Fe3+ has severe undesirable effects on the red pigment; EDTA and β-CD can not only slow down the discoloration speed of the red pigment but also effectively inhibit the effects on red pigment containing Fe3+. And it also showed that the colour-protect action of EDTA is better than the colour-protect action of β-CD, so as to increase the application and value of red pigment.

Key words: Nitraria tangutorun Bobr.fruit; red pigment; Fe3+; stability; EDTA(ethylenediaminetetraaceticacid); &beta, -CD;
