What is "emulsifying"

Usage examples of "emulsifying".

Almost every day they came back to the trailer park with samples of new materials: sulphuric acid, sorel cements for the vault mortar, ammonium nitrate explosives, a calcium cyanamide rover fuel, polysulfide rubber, silicon-based hyperacids, emulsifying agents, a selection of test tubes holding trace elements extracted from the salts, and, most recently, clear glass.

This makes sense, since bile is particularly useful in emulsifying fat and making it easier to digest.

A fatty meal will stimulate the production of unusually high quantities of cholecystokinin, which will stimulate the gallbladder strongly, which will squirt a greater-than-usual supply of bile salt (the emulsifying ingredient) into the intestine, which will emulsify the fat that started the whole procedure and bring about its digestion.
