Influence of Nigella sativa L. Extract on Physico‒Mechanical and Antimicrobial Properties of Sago Starch Film

摘要: In this study, some physical and mechanical properties as well antibacterial activity of sago starch films incorporated with methanol extract from Nigella sativa L. seeds (0, 1, 3, 5 10%) were investigated. The results showed that increasing concentration the caused significant (P < 0.05) increment in thickness (0.06‒0.12 mm), moisture content (8.72‒11.19%, wet basis), water solubility (21.31‒25.62%), absorption capacity (1.98‒3.45 g water/g dry film), vapor permeability (1.63 × 10− 11‒2.59 × 10− 11 g/m.s.Pa) films. Tensile strength Young’s modulus changed range 4.27‒6.43 MPa 80.19‒118.55 MPa, respectively. Compared to control, composite represented more flexibility elasticity was continually enhanced percentage extract. good antimicrobial against both Gram-positive Gram-negative bacteria presumably due phenolic compounds
