Effects of Sodium Alginate and Chitosanon Physicochemical Properties of Encapsulated Sweet Basil Leaf Extract

Abstract
The aim of the present study was to evaluate the physicochemical properties of encapsulated sweet basil leaf extract. Antioxidant activities of sweet basil leaf extract were analyzed in terms of total phenolic content, DPPH and ABTS assay and the magnitude of physicochemical properties were evaluated by stereo microscopy, encapsulation efficiency of capsules and solubility. It was found that the extract contained total phenolic content of 21.406 mgGAE/ g sample. The DPPH and ABTS activities, it was showed that the IC50 of DPPH and ABTS were 4.78 and 2.96 mg/ml, respectively. The morphology of the capsules using sodium alginate as wall material was spherical shape, while that using chitosan was irregular. The size of sodium alginate capsule was smaller and the particle sizes were between 1.33-3.08 mm. The solubility of capsules was not different. The encapsulation efficiency of sodium alginate capsule was higher than the chitosan: therefore, it was possible to increase the efficiency of encapsulated sweet basil leaf extract by coacervation.
