Disclosed is a method of preparing N-alkylated chitosan derivatives by treating chitosan with an acid and subsequently reacting the chitosan with an alkylating agent in the presence of a base. Also provided are novel N-alkylated chitosan derivatives.
Provided herein are chitosan-containing formulations, methods of making such formulations, and methods of using such formulations. Chitosan contemplated for use herein is preferably of high quality and its source is preferably of crustacean origin. The formulations contemplated herein are aqueous, either liquid- or viscous-like, varying in concentration and type of chitosan and acid used, and may include other components. Their uses are diverse, for oral/dental administration or topical/surface application to subjects (e.g. humans or animals) in need thereof or even food commodities, aiming to maintain a good condition where it is applied or contributing to health enhancement, healing, disease prevention or treatment. The present invention also relates to concentrated solutions that may be used for the formulation of other products.

CHITOSAN DERIVATIVES AND METHODS FOR PREPARING THE SAME
Disclosed is a method of preparing N-alkylated chitosan derivatives by treating chitosan with an acid and subsequently reacting the chitosan with an alkylating agent in the presence of a base. Also provided are novel N-alkylated chitosan derivatives.
Provided herein are microencapsulated chitosan materials and formulations containing same, methods of making such formulations, and methods of using such formulations. Application of a microencapsulation coating on chitosan materials and formulations containing same renders possible the use of chitosan materials for different, novel chitosan-based dietary applications with the primary aim to decrease intestinal absorption of fat and enhance overall health, without interfering with or reducing food palatability. The present invention provides methods to microencapsulate highly effective chitosan or chitosan salts to moderate their interaction with food components and mask any off-flavors and off-tastes but allow rapid chitosan solubilization under gastric acid conditions and simultaneous binding of ingested lipids. Chitosan contemplated for use herein is preferably of high quality with high fat-binding capacity, and its source is preferably of crustacean origin.
The present disclosure generally relates to improved processes for making chitosan salts and products formed by such processes. In certain embodiments, the processes disclosed herein provide the ability to make high-grade chitosan salts at lower cost and with improved environmental friendliness.
