Abstract
A process of preparation of collagen containing in major proportion insoluble collagen is disclosed, including rinsing and washing the collagenic tissue, acidifying the ground material pH value 1 to 4 to get a collagenic paste which is diluted in a diluting solution to get the collagen gel having a concentration in collagen lower than about 2.5 by weight expressed in dry collagen, and performing a shearing stirring at high speed producing ultrasonic effect to get a substantially homogeneous collagenic gel. The collagen has improved mechanical resistance and thermal stability.
