| Research Abstract |
Collagen of animal by-products(e. g., chicken skin) was utilized for developing a novel food ingredient. Heat-denatured collagen was hydrolyzed by protease treatment. Hydrolyzed collagen was heat-treated after the addition of carbohydorate(e. g., Xylose). By these procedures, a Maillard reaction product from collagen was obtained. This product showed a strong antioxidative activity in vitro. Also, in vivo assay showed the decrease of oxidative stress marker value(serum hydoroxiperoxide value) and the antihypertensive effect. Palatability of this products was also preferable.
