Preparation and characterization of sodium alginate-based edible film with antibacterial additive using lemongrass oil
Sodium alginate films at various concentrations of glycerol (0.4, 0.6, and 0.8% v/v) were prepared and characterized. The thickness, water solubility (WS), water vapor transmission rate (WVTR), tensile strength (TS), elongation at break (EB) and Young’s Modulus (YM) of the films were affected by the...
