UNIAXIAL and COAXIAL NANOFIBER ENCAPSULATION of THYME and CARDAMOM OIL

Abstract

Volatile antimicrobial oils like thyme oil or cardamom oil containing bioactive ingredients adversely affectmicroorganism’s cells. Bioactive ingredients should be protected from ambient conditions of processingand storage to exhibit their desired effects during consumption. Therefore, encapsulation of bioactiveingredients plays an important role in terms of their efficiency. Nanofiber encapsulation offers lots ofadvantages compared to the other encapsulation methods. In this study, the objective was to investigatethat whether thyme oil or cardamom oil can be electrospun uniaxially or coaxially. To obtain uniaxialnanofiber, 20% gelatin-acetic (w/v) acid solution was prepared by gelatin dissolved in 20 % acetic acid-watersolvent (v/v). The feed solutions were prepared by mixing of gelatin solution and thyme or cardamomoils (9:1). For coaxial geometry, same antimicrobial oils were encapsulated with 20% gelatin-acetic acidsolution (w/v). The core was only the oil and the shell was the gelatin solution, which each was pumpedby two different micropumps. Nanofiber structure was obtained for the samples containing thyme oilwhereas no fiber formation was attained for the samples with cardamom oil. In the future, differentelectrospinning process parameters may be applied to obtain nanofibers containing cardamom oil. Inaddition, the release kinetics of nanofiber encapsulated oils may be studied at different conditions forvarious objectives. The outcome of this study will help such studies that will be conducted in the future
