橙子果汁中色素的理化性质研究

通过实验，对橙汁果汁色素理化性质做了初步的探索，研究金属离子，氧化剂及还原剂，常用的食品添加剂，酸碱和光照对色素的影响，结果表明：金属粒子、低浓度的氧化剂和还原剂对色素的影响不大；不同食物添加剂对色素有不同的增色或消色作用；色素对光敏感，随着光照时间的增加稳定性减弱．

Studies of Physics and Chemistry Properties of Pigments in Orange Juice

Through a series of experiments,we have done a preliminary exploration for the orange juice pigment of physical and chemical properties,studied the effect of metal ions,oxidizing and reducing and reducing agent,commonly used food additives,acid-base and light on pigment.The results show that:metal particles,the low concentration Oxidants and reductors have little impact on the pigment and different food additives have different pigments or enrich Consumers color;pigment is light-sensitive,and while light in...
