Hydrocolloids FAQ – Gellan Gum, Pectin, Xanthan & More

Dr. Colloids – Your Hydrocolloid Expert

Dr. Colloids is the technical ambassador of CAG and a passionate expert in hydrocolloid science. With decades of experience in food and functional ingredient technology, he specializes in understanding how hydrocolloids behave in real-world formulations.

On our website, Dr. Colloids serves as your technical guide. Whether you are trying to improve texture, stabilize a beverage, prevent protein flocculation, enhance suspension, or design a new hydrocolloid blend, he is here to help.

Dr. Colloids enjoys spending time in the lab exploring new hydrocolloid combinations and discovering unexpected synergies between natural gums. He believes that the most elegant formulations often come from simple ingredients used in the right way.
