Optimization of the Formulation of Sago Starch Edible Coatings Incorporated with Nano Cellulose Fiber (CNF)

This study aimed to produce new edible coatings based on the mixture of sago starch, cellulose nanofiber (CNF), glycerol, and tween-80.The effect starch (5–10 g starch/100 ml distilled water), CNF (0.5–20% w/w), glycerol (10–30% tween-80 (0.5–10% w/w) concentration contact angle (CA), water vapor permeability (WVP), oxygen (PO2) tensile strength (TS) properties were optimized using factorial experimental design (2k).The result showed that linear model for all independent variables was significant (<i>P</i><0.05) responses (dependent variable).The depicted a (p < 0.001) positive angle; statistically WVP, PO2, TS; dependent variables, whereas only affected WVP. The optimum concentrations CNF, predicted be 5 g/100 water, 20% w/w, 10% 0.5% w/w respectively obtain minimum angle, maximum TS. data coating formulation in good agreement with value. work revealed potential starch/CNF could effectively produced successfully applied food.
