Enhanced stability of natural vitamin E from palm oil by forming inclusion complexes with cyclodextrin and its application on PLA fabric

Abstract

Natural vitamin E was extracted from crude palm oil and palm fatty acid distillate, both of which were converted into biodiesel before the extraction process. To enhance the stability of vitamin E, the study investigated the formation of inclusion complexes between vitamin E and β-cyclodextrin and hydroxypropyl-β-cyclodextrin. The results demonstrated improved thermal and light stabilities, prolonging the shelf life at room temperature while maintaining the antioxidant activity of vitamin E. Furthermore, the study successfully applied these complexes to poly(lactic acid) (PLA) fabrics, a biodegradable natural polymer, without altering their appearance. These findings underscore the potential of utilizing natural vitamin E from CPO and PFAD sources in the form of inclusion complexes for textile applications.
