the excessive acid is partially neutralized and the salts are washed out by exchanging the water several times. Gelatine can also be obtained from ossein by acid treatment – the concentration of the acid and the exposure time must be adjusted accordingly. Gelatine produced this way is referred to as Type A gelatine (A = acid). Alkaline Treatment
