Response surface methodology model to optimize concentration of agar, alginate and carrageenan for the improved properties of biopolymer film

The present study intended to develop improved biopolymer film from seaweed polysaccharides. The quantity optimization of polysaccharides for the composite film was sought by empirical response surface methodology. To achieve the goal, Box–Behnken model was applied to the concentration of three independent variables, viz. agar (1.0–2.0% w/v), alginate (1.0–2.0% w/v) and carrageenan (1.0–2.0% (w/v). The glycerol was used as a plasticizer and kept...
