Effect of Emulsifiers and Wall Materials on Particle Size Distribution and Stability of the Blended Essential Oils Nanoemulsions

Abstract

In the present work, microencapsulation of the essential oil blend (clove + lemon peel + thyme) was successfully used to produce a product that can be used as food additives or in the pharmaceutical industry for the manufacture of a food supplement or so-called nutraceutical of plant origin. The characterization of the powder of the microcapsules made it possible to observe that the essential oil was successfully incorporated into the coating matrix. This was designed by the wall material, namely maltodextrin represented a barrier allowing the protection of the active principle, the control of its release and the property retention of the encapsulated essential oil for a long time. This powder of microcapsules of essential oil mixture can be successfully used for medical purposes to remedy certain pathologies, in particular for its antioxidant, antibacterial and anti-inflammatory properties.

Molecular inclusion encapsulation of orange essential oil: Effect of the drying method on physical, chemical, structural characteristics and stability

“…Referente a la higroscopicidad, el mayor y menor valor fueron 4,89 ± 0,007 y 0,20 ± 0,001%, respectivamente; siendo el primero calculado para secado por atomización a 200 °C y el segundo para liofilizado. Según Yeddes et al (2022), la higroscopicidad de las micropartículas es baja debido a la naturaleza hidrofóbica del aceite esencial (AE) que no le permite absorber agua, aunque este valor puede aumentar junto al contenido de AE. Por otro lado, existe una relación directamente proporcional ya que las macropartículas secadas a mayor temperatura poseen mayor higroscopicidad esto se debe a que, al incrementar la temperatura de secado, existe una mayor remoción de agua por lo cual al ser sometidos a un ambiente de humedad relativa alta, genera una mayor absorción de agua para alcanzar el equilibrio (Sánchez, 2016).…”

“…The polydispersity index value close to zero indicates a homogeneous particle distribution. While the PI value exceeding 0.5 indicates high heterogeneity, it can increase the occurrence of agglomeration due to collisions between particles [20].…”
