When the tablets are soaked in water for 5- 10 minutes, they will absorb water, swell and soften, and then they will be heated in water to dissolve into colloid, showing a transparent and clear state. Gelatine tablets will become gel after being heated and cooled to below 35-40 C. If the water solution is boiled for a long time, its properties will change due to decomposition, and it will not form gel after being cooled. Therefore, pay attention to the heating time and temperature.
