ABSTRACT:
Improved yield and gelatin quality is obtained by extracting conditioned collagen-containing material with water at lower temperature and shorter time conditions than previously used to remove high quality gelatin as quickly as possible. Very high quality gelatin is extracted initially. Acid conditioning yield is also improved by controlling pH between 1.5-2.0.
