Introduction/Background. Encapsulation processes are beneficial in a variety of fields from pharmaceuticals to food preparation. The objective of this study was to develop a shell to encapsulate a 10% wt. polyacrylamide gel. The shell needed to be impermeable enough to retain most of the water content, while still maintaining the ability to burst under pressure and release the contents over a surface. Preliminary testing (Method 1) was performed using commercially available 0.50 caliber (0.50 inch diameter) gelatin-shell paintballs. These capsules seemed to demonstrate the desired capsule properties, prompting further studies of gelatin encapsulation. Three solutions containing gelatin, water, and glycerol were prepared and tested (Method 2) to determine an optimal gelatin recipe for encapsulation of the polyacrylamide gel..
