L-Carnosine (beta-alanyl-L-histidine) is a dipeptide of the amino acids beta-alanine and histidine.It is highly concentrated in muscle and brain tissues.Researchers have shown that carnosine has a number of antioxidant properties that may be beneficial.L-Carnosine has been proven to scavenge reactive oxygen species (ROS) as well as alpha-beta unsaturated aldehydes formed from peroxidation of cell membrane fatty acids during oxidative stress.

Function :

1).New types of food additives.
2).Carnosine is composed of a β alanine and histidine dipeptide, animals can be synthesized in the body.
3).Carnosine caused by free radicals and metal ions significantly inhibited lipid oxidation in meat processing carnosine can inhibit lipid oxidation, color protection.Carnosine and phytic acid oxidation resistance beef.Diets supplemented with 0.9 g / kg carnosine can improve the color and improve the oxidative stability of skeletal muscle, has a synergistic effect with vitamin e.
4).In the use of cosmetics that can prevent skin aging and skin whitening effect, carnosine can prevent free radical caused by smoking, which is more than the sun's rays free radicals damage the skin and radicals are highly reactive atoms or radicals in the human body, can be oxidation of other substances in the body.
5).Carnosine has antioxidant, which is a natural antioxidant.
6) people on cloudy eye lens transmittance is enhanced.Used as raw material in carnosine antioxidant agents can treat senile cataracts.
7).Olfactory sensing object, can promote wound healing, especially used in surgical treatment of oral medication
