摘要: 本实验研究了草原樱桃果实中红色素的稳定性,结果表明:pH值对该色素的影响明显,宜在酸性食品中应用;金属离子(Na+、Al3+、Zn2+)对该色素有一定的增色作用;Cu2+(<0.1mol/L)、葡萄糖、VC(<0.1mol/L)对该色素影响作用很小;蔗糖具有一定的降解作用,但无明显的不良影响;而Fe3+、氧化剂(H2O2)、还原剂(Na2SO3)则有严重的破坏作用;低浓度的(<1%)防腐剂苯甲酸钠对该色素无影响,高浓度(>1%)的则有明显的降解作用。

Abstract: The stability of red pigment from Gerasus fruticosa was investigated in this paper. The results showed: pH exerteda large effect on the pigment stability, while lowering the pH in the range 1~4 had little effect. Of the various metallic ions tested,it was found that Na+、Al3+、Zn2+ had effects of tone fortification on the pigment; Cu2+(<0.1mol/L)、glucose、ascorbicacid had little effect and sucrose was shown to have a definite effect of degradation. However Fe3+ had severe undesirable effect.Furthermore, hydrogen peroxide and sodium sulfite were observed to have marked increase in the rate of the pigment degradation;Besides, preservative sodium benzoate had no undesirable effect at lower concentrations(<1%), but at higher concentrations(>1%)had effect of obvious degradation.

Key words: Gerasus fruticosa, red pigment, stability
