Abstract


In this study mulberry leaf extract biocompounds were encapsulated with sodium carboxymethyl cellulose (0.55%, 0.70%, and 0.75% w/v) or maltodextrin (8%, 10%, and 12% w/v). The outcome of this work demonstrated that maltodextrin showed the highest encapsulation efficiency towards the phenolic acids and 1-deoxynojirimycinin whereas the flavonols and gamma-aminobutyric acid were best encapsulated by sodium carboxymethyl cellulose. Moreover, the antioxidant properties of the encapsulated powders were found to be associated with their nutraceutical constituents. In addition, the powders produced with sodium carboxymethyl cellulose were typified by suitable hygroscopicity, wettability time, glass transition temperature, and bulk properties than those obtained with maltodextrin which was characterized by desirable porosity, water solubility, moisture content, water activity, color, particle, and flowability properties.
