What are phycocolloids?\xa0 |
| Answer» Phycocolloids are basically polysachharides that are derived from seaweeds.The three major phycocolloids are\xa0alginates,\xa0agars, and carrageenans. Alginates are extracted primarily from brown seaweeds, and agar and carrageenan are extracted from red seaweeds. These phycocolloids are polymers of chemically modified sugar molecules, such as\xa0galactose\xa0in agars and carrageenans, or organic acids, such as mannuronic acid and glucuronic acid in alginates. Most phycocolloids can be safely consumed by humans and other animals, and many are used in a wide variety of prepared foods, such as ready-mix cakes, instant puddings and pie fillings, and artificial dairy toppings. | |
