Abstract
The present invention describes a covalent biomaterial which is formed by gelling feruloylated arabinoxylans that are biodegradable and which can be used for the oral administration of insulin directed to the colon. The present invention also relates to a method for producing enzymatically covalently crosslinked particles. The aforementioned pharmaceutical composition is suitable for use in the biomedical or pharmaceutical industry as a non-invasive treatment for the oral administration of insulin or insulin analogs for patients with type 1 diabetes.
