COLLAGEN AND ITS AQUEOUS COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide collagen and its aqueous composition both excellent in thermal stability, not causing decrease in viscosity, transparency, etc., while being preserved and having stabilized properties. SOLUTION: Collagen originating from fowls has a thermal denaturation temperature of 40 to 47 deg.C, a viscosity survival rate of >=60% when stored at 35 deg.C for 4 h. and persistence permeability of >=97% when measured at 430 nm. This aqueous composition is constituted using the collagen. The collagen preferably is I-type collagen originating from chickens and the aqueous composition preferably contains at least one kind selected from the group consisting of a 1-20C alcohol and its fatty acid ester.
