摘要
对黑豆色素在pH值、温度、光照、氧化剂、还原剂、金属离子等不同因素影响下的稳定性进行了研究。结果表明:黑豆色素在酸性条件、避光条件下稳定性好;色素耐热能力较强;K+、Mg2+对色素影响效果不明显,Fe3+、Cu2+、Zn2+对黑豆色素稳定性影响较大,色素的抗氧化、抗还原能力较差。
Stabilities of black-soybean pigment on pH, temperature, sunlight, oxidant, reductant, amino acid and metal-ion were studied. The results indicated that black-soybean pigment was stable at acidic and sheher circumstance, heat-resistant. K^＋,Mg^2＋ had not significant effect on stability of pigment, while Fe^3＋, Cu^2＋, Zn^2＋ had obviously effect on its stability. The pigment got poor stability to oxidant and reductant.
