What are hydrocolloids??
Hi Habiba,
Hydrocolloids are substances that have the capacity to hold water. These substances absorb water and increase in size.
Algin (red algae) and carrageen (brown algae) are some important sources of natural hydrocolloids. These hydrocolloids are used in the food industry in the manufacturing of jellies. Some hydrocolloids such as agar is used in the making of culture media for the growing microorganisms.
Hope this answer helps,
All the best!
