Study on the Nitrous blood red pigment coloring agent for food

以健康的猪、牛、羊的新鲜牲血为原料，经化学提取、合成及酶解等简单步骤，制成了食品着色剂亚硝基血红色素。该产品可替代具有毒性作用的亚硝酸盐而直接加入食品着色，是一种无毒副作用的理想的调味食品着色剂，同时也增强了食品的营养成分。

The nitroso blood red pigment colouring agent for food can be made from fresh livestock blood of healthy pigs,oxen and sheep by means of chemical extraction,synthesis,enzymolysis,etc As an ideal nonpoisonous flavoring colouring agent.This product can take place of toxicant nitrous acid salt and be directly added to the food to colour food,and enhance food nutritional composition.
