PREPARATION OF GLUE OR GELATINE
Definition statement

This place covers:

Pre-treatment of collagen-containing raw materials for the manufacture of glue or gelatine from raw materials, e.g. by extracting or by heating.

Stabilisation of solutions of glue or gelatine.

Preparation of water-insoluble gelatine.

Drying of glue or gelatine.

Glue or gelatine products per se resulting from the above-mentioned methods, e.g. stabilized or granular gelatine, if no o

ther group for the produced compound exists.
