Macromolecular Rapid Communications

Researchers from SANKEN (The Institute of Scientific and Industrial Research), at Osaka University demonstrated a method for drying cellulose nanofiber (CNF) that retains the unique properties of the thickening agent. High transparency, high viscosity, and controllable viscosity were restored with simple stirring after the CNF was dehydrated from an organogel. Our powder had a much smaller volume than freeze-dried CNF, which will facilitate more efficient transport and storage. The method is expected to have a significant impact on food and cosmetics manufacturing.
