Carrageenan

/ˌkærəˈɡiːnən/ noun

Definition

A thickening and stabilizing substance extracted from red seaweed, widely used in food production, cosmetics, and pharmaceuticals.

Etymology

Derived from 'carrageen' with the addition of the chemical suffix '-an'. The name preserves the Irish origin of the seaweed source material.

Kelly Says

Carrageenan is a perfect example of how seaweed becomes chemistry—this single ingredient stabilizes ice cream, prevents puddings from separating, and keeps cosmetics smooth, making it one of the most-used food additives worldwide.
