Abstract
Disclosed herein are gelatin particles that have been crosslinked without using a crosslinking agent and are easily taken up by cells themselves, and a method for producing such gelatin particles. The gelatin particles are made of self-crosslinked gelatin and have a particle diameter of 0.010 μm or more but 5.0 μm or less. The gelatin particles can be produced by discharging droplets of a liquid containing melted gelatin into air in a heating tube or a drying chamber and drying the droplets to form the gelatin into particles under conditions where a difference between the temperature in the heating tube or the drying chamber and the temperature of the liquid is 235° C. or less and further by crosslinking the gelatin forming the particles.
