摘　　要：为了解金属辅色因子在不同因素下对花色苷呈色的影响,以矢车菊素-3-O-葡萄糖苷为原材料,采用CIELab颜色评估法对其相关颜色指标进行分析。结果表明,K^(+)、Mg^(2+)、Al^(3+)的加入可引起色素溶液的颜色加深,并有效增强色素溶液的贮藏稳定性,且Al^(3+)的辅色效果要优于K^(+)、Mg^(2+)。金属辅色因子的加入可有效延缓花色苷在贮藏期内的颜色变化。同时,K^(+)、Mg^(2+)、Al^(3+)的添加可降低由于p H升高造成的颜色损失,特别在强酸(p H<3.0)条件下更利于呈色效果的表达。此外,还研究了乙醇、葡萄糖及酚酸对金属离子辅色作用的影响,这些结果将为深入研究金属离子辅色作用,以及金属离子在保护食品色泽中的应用提供数据参考。In order to understand the co-pigmentation effect of metal ions on the coloration of anthocyanin under different conditions,cyanidin-3-O-glucoside was used as the raw material,and CIELab color evaluation was used to analyze the relevant color indicators.The results showed that the addition of K^(+),Mg^(2+),and Al^(3+)could lead to a deepening in the color of pigment solution,effectively enhancing its storage stability.Notably,the co-pigmentation effect of Al^(3+)was superior to that of K^(+)and Mg^(2+).The inclusion of metal co-pigments could effectively delay the color change of anthocyanin during storage.Additionally,the addition of K^(+),Mg^(2+),and Al^(3+)could alleviate the color loss caused by an increase in pH,especially under strong acid conditions(pH<3.0),which facilitated a more pronounced color expression.Moreover,the effects of ethanol,glucose,and phenolic acids on the co-pigmentation effect of metal ions were also studied.These results could provide data and reference for the in-depth study of the co-pigmentation effect of metal ions and their application in preserving food color.
