Optimization of Cellulose-Based Film Formulation for Fresh Egg Coating Using Response Surface Methodology
Fresh eggs are an excellent protein source. Nevertheless, several problems - such as weight losspoultry industry. Methylcellulose (2.00% w/v) and hydroxypropyl methylcellulose (1.00% w/v) -based ediblefilm was formulated to study the effects of polyethylene glycol-400 (PEG-400) and a stearic and palmitic acidblend (SPB) on water vapor permeability (WVP) and tensile properties using response surface methodology.The composition of these two variables was designed by a central composite design (CCD) approach.The analysis of variance (ANOVA) for the models developed for WVP, tensile strength (TS) and elongation(E) were significant (P < 0.05). These models did not exhibit any significant lack of fit (P < 0.05), which suggestedthat they adequately described the true functions. Based on these results, quadratic models were selectedfor WVP, TS and E. It was found that model development could be employed as a tool for optimizationof the cellulose-based coating formulation. The approach presented in this study can provide a very usefulguideline to optimize other coating systems very efficiently.
