phycocolloid
Quick Summary
Phycocolloids are polysaccharide hydrocolloids derived from brown or red seaweeds. These substances are extracted from the cell walls of many seaweeds using hot water.12
The three main types of phycocolloids are:
* Alginates: Extracted primarily from brown seaweeds, used in ice cream, syrups, and candy bars.2
* Agars: Extracted from red seaweeds, used in pie fillings, canned goods, and laboratory cultures.2
* Carrageenans: Extracted from various red seaweeds, used in dairy products, shampoos, and cosmetics.2
These compounds are polymers of modified sugar molecules or organic acids and are generally safe for consumption.2
