摘　　要：鉴于目前广泛使用的天然红色素胭脂虫红色素在生产和应用上均存在一定的不足,为了克服其缺点,开发新型天然红色素,我们对南极红色素和胭脂虫红色素进行了一系列性质比较实验,探讨了南极红色素中桔青霉素的含量,并针对南极红色素和胭脂虫红色素在吸收波长、色价以及pH稳定性方面进行了对比研究。结果表明,南极红色素中不含桔青霉素,且南极红色素和胭脂虫红色素的最大吸收波长分别是528nm、514nm,属于同一色系,色素色价分别是136.5和118.2;同时南极红色素在pH2-11范围内颜色基本不变,而胭脂虫红颜色发生变化,其pH稳定性整体优于胭脂虫红色素,未来在食品添加剂行业的应用上具有广阔的市场前景。Cochineal red pigment is widely used pigment nowadays,but it has disadvantages in production and application.In order to overcome these disadvantages and develop new type of natural red pigment,Antarctica red pigment and Cochineal pigment properties were compared,such as citrinin content,absorption wavelength,pigment value and pH stability.The results showed that the Antarctic pigment did not contain citrinin,the maximum absorption wavelengths of Antarctic pigment and Cochineal pigment are 528nm and 514nm,respectively.Antarctic pigment and Cochineal pigment belong to the same color family,and the color values are 136.5,118.2,respectively.Antarctic pigment is stable under pH2-11,which is more stable than that of cochineal pigment.Therefore,Antarctic pigment may have a broader market in food industry in the future.
