Effect of coating materials for microencapsulation of basil oil using spray drying

Abstract

Ocimum basilicum L., commonly known as “sweet basil” is a plant with high medicinal values and antioxidant potential. Basil oil is rich in phenolics and terpenoid compounds and used as a potential antioxidant, antimicrobial and anti-inflammatory agent. Present research work was aimed to study the effect of wall materials for basil oil microencapsulation. Various wall materials, including sodium alginate (SA) and sodium caseinate (SC), were combined with maltodextrin (MD) in two different ratios (1:2 and 1:1) were used for microencapsulation through spray drying. Among the evaluated wall materials, a combination of MD+SA at a ratio of 1:1 bestowed excellent performance both in terms of encapsulation efficiency and morphological characteristics of the prepared basil oil microcapsules. © 2020, IndianJournals.com.
