This is what is the significance of emulsification of fat because digestion and absorption of lipids depend on emulsification. Pancreatic lipase breaks down these emulsified fats into fatty acids and glycerol. The smaller globules of fat are broken down by bile salts, creating a milky emulsion. Process of emulsification: how does emulsification work Salts are then secreted and kept in the gallbladder. In digestion, the small intestine is where emulsification takes place by breaking it down into smaller fat globules. It can be created mechanically (using a high-energy) or chemically (low-energy method). Image Source: Emulsifier for oil and water mixtureĭispersing one liquid into another immiscible liquid is known as emulsification. Can make oil and water mix for prolonged lengths of time. That mixing, though, ends quickly! After a few minutes, you can recheck the container to see that the water and oil have separated. Have you shaken water and oil before? If so, you are aware that they did mix briefly. Water and oil don’t mix when you add one to the other. Oil is a nonpolar molecule (Hydrophobic).Water is a polar molecule (Hydrophilic).Water molecules will group in a container containing oil, and oil molecules will group in a container containing water, generating two separate layers. However, oil molecules cannot establish hydrogen bonds. These charges enable the molecules to create hydrogen bonds with polar molecules. Because they are polar and have a small positive charge on one end and a slight negative charge on the other. Water molecules cling together because one water molecule’s positive end is drawn to another’s the opposing end. It is because water is a polar molecule, meaning that one end of it is negatively charged, the other positively charged. Image Source: Do oil and water mix together. The polar chemistry of the base stock and oil additions affects the dew point temperature. Condensation causes fat to become cloudier as it gets cooler. When oil reaches its dew point, it has a 100% concentration of dissolved water. Image Source: Does oil have water in it?
