КСАНТАН: ДОСЛІДЖЕННЯ ІННОВАЦІЙНИХ РІШЕНЬ МОДИФІКАЦІЇ ТА ПРОМИСЛОВОГО ЗАСТОСУВАННЯ

The article presents a review of current approaches to the modification of xanthan aimed at expanding its functional properties. The chemical structure of xanthan is analyzed, with particular emphasis on the organization of the main polysaccharide backbone and side chains containing carboxyl, hydroxyl, acetyl and pyruvate groups. Their key role in the formation of intermolecular interactions, gel network development, sorption capacity and the immobilization of biologically active compounds and modifying agents is demonstrated. Available data on the conditions of chemical engineering of xanthan-based systems are summarized using examples of various modification strategies, and structural features of modified gel matrices are discussed. The main application areas of xanthan in the chemical, food, pharmaceutical, cosmetic, medical, water treatment and petroleum industries are outlined, with illustrative examples of technological performance. The prospects of xanthan as a versatile platform for the development of composite materials and controlled delivery systems for active components are highlighted. The need for further research focused on the design of modified xanthan forms with predictable structure–function relationships to advance chemical engineering applications is emphasized.
