The present work deals with the design and process optimization for preparation of lactoferrin nanoparticles as carrier for delivery of curcumin (CLf-NPs) using quality by design (QbD) approach. Desolvation technique was selected for preparation of Lf-NPs. The concept of QbD was followed in stepwise manner including risk analysis FMEA methodology. Plackett-Burman screening design employing eight factors and two levels was selected for screening study and custom design was selected for further analysis. Curcumin was used as model polyphenol for assessing the encapsulating efficiency of Lf-NPs.
Keywords: Critical quality attributes; desolvation; lactoferrin; optimization; robustness.
