A question would have from most softgel manufacturers, can the color mixer generate bubble again in the cooked gelatin mass? The answer is NO.

If the gelatin mass has done the vacuum and bubble deaeration thoroughly, no new bubble generating when color mixer mixing the cooked gelatin mass with color agent, because its mixing in the gelatin mass, no contact with air, its only physical movement. If there is bubble, it means there is bubble in the cooked gelatin mass itself, color mixer mixing only change the distribution way of the original bubbles, besides color mixer is helpful to disperse the existing bubbles in gelatin mass, expedite gathering of these existing bubbles, more helpful for its deaeration after still kept, (the principle of fluid mechanics).
