摘要: 以黑果小檗果实为实验材料提取色素,并从光、温度、还原剂、氧化剂、防腐剂和不同金属对色素稳定性的影响进行了初步研究,结果表明:该色素属于花色苷类;适合在酸性条件下使用(pH<7);耐光性好;对热有一定的耐受性:对低浓度氧化剂H2O2(<0.1%)有一定耐受性;对还原剂Na2SO3耐性差;对防腐剂苯甲酸钠耐性差;蔗糖对色素无不良影响;大多数金属离子对色素无不良影响,而Fe3+、Fe2+、Sn2+和高浓度Pb2+ (>50.0×10-3mol/L)对色素有较大影响。

Abstract: The fruits of Berberis heteropoda Schrenk were used as raw material to extract the red pigment.The experiment studied the effects of light,heat,reductant,oxide,preservative,sucrose and metal ions on the stability of the pigment.The results showed that the pigment of Berberis heteropoda Schrenk is a type of anchocyanin.It can be applied according to the condition of pH<7.It is strong in light endurance to some extent,good also in enduring heat and low consistence H2O2(<0.1%).But it is poor in corrosion resistance against Na2SO3 and sodium benzoate.It is also found that sucrose and most of metal ions do not exert negative effects on the stability of the pigment,except Fe3+,Fe2+and high consistence Pb2+(>50.0×10-3mol/L),which show effect to some extent.
