Abstract: The present invention relates to a process for the production of collagen from animal intestines etc. It is characterized in that the starting material is mixed with ice-water at a pH of 5,5, that the mixture is disintegrated and then heated to 40.degree.-42.degree. C. and hydrolysed at a pH of 10,5 using a proteolytic enzyme. After finishing of the hydrolyses pH is regulated to 5,5 and the collagen is separated and collected. The invention also encloses collagen produced through the process and a number of new application areas for collagen.
