However, there are a handful of alternative phrases and words to describe this process. These include "setting," "solidification," "coagulation," "jellification," "thickening," and "congealing." Each of these words implies the transformation of a liquid substance to a more solid form, whether through the use of heat, chemical agents, or other means. Regardless of the term used, gelation plays an essential role in a wide range of industries, including food, pharmaceuticals, and cosmetics.
