Emulsifiers in Fat Digestion: How Bile Salts Aid Absorption

An emulsifier stabilizes emulsions. In fat digestion, emulsifiers break dietary fats into smaller droplets in the small intestine, increasing surface area for lipase action and absorption.

Bile salts (synthesized from cholesterol in liver, stored in gallbladder) are natural emulsifiers. They break large fat droplets into smaller ones for efficient lipase digestion. Natural emulsifiers like lecithin (egg yolks, soybeans) also aid fat digestion. Artificial emulsifiers are used in food processing for texture, flavor, stability.
