Because
of its antioxidant, antiglycator and metal chelator properties, carnosine
supplements have been proposed as a general anti-aging therapy. Carnosine
containing products are also used in topical preparations to reduce wrinkles on
the skin.

1. The
new food additives.
2.
Carnosine is composed of a beta alanine and histidine dipeptide, the animal can
be synthesized in the body.
3.
Carnosine caused by free radicals and metal ions has significant inhibitory
effect on lipid oxidation, carnosine in meat processing is to inhibit the
action of the fat oxidation and protecting the nude. Carnosine and phytic acid
oxidation resistance to beef. Added in the diet of 0.9 g/kg carnosine, can
improve the color and improve the oxidation stability of the skeletal muscle,
and has the synergism with vitamin E.
4. In the
use of cosmetics, can prevent skin aging and skin whitening effect, carnosine
can prevent free radicals caused by smoking, and this kind of free radical is
better than the sun's rays can damage the skin and free radicals are highly
reactive atoms or radicals in the human body, can carry on the oxidation of
other substances in the human body.
5.
Carnosine has antioxidant properties, it is a kind of natural antioxidants.
6. The
turbidity of the human eye light transmittance of crystal can be enhanced.
