Elucidating interfacial-function relationships of lactoferrin-cellulose nanofibril complexes via multidimensional spectroscopy and QCM-D: interfacial anchoring and bulk stabilization mechanisms in robust Pickering emulsions
Pickering emulsions stabilized by natural biopolymers have garnered significant interest due to their safety and functionality. In this study, lactoferrin (LF) and cellulose nanofibril (CNF) were complexed via electrostatic interactions under varying pH conditions. Multidimensional spectroscopic and interfacial tension analyses revealed that LF dominates the interfacial behavior of the complexes. QCM-D demonstrated that LF-CNF complexes formed a denser interfacial layer (apparent adsorbed mass ∼ 287.0 ng/cm2), approximately 1.8 times higher than LF alone (∼159.4 ng/cm2) and 12 times higher than CNF alone (∼22.5 ng/cm2). When used as Pickering emulsion stabilizers, all emulsions exhibited shear-thinning behavior. The 1.0 wt% LF-CNF complexes provided the finest droplet size, highest uniformity, and longest storage stability (up to 28 days). This study clarifies the interaction mechanisms and interfacial behavior of protein-polysaccharide complexes, offering theoretical guidance for designing high-performance food-grade emulsifiers with natural origin.
Chitin nanofibrils (CNs) and lignin nanoparticles (LNPs) are renewable nanomaterials whose complementary surface chemistry enables the formation of chitin nanofibril–nanolignin (CN–NL) complexes. This review addresses a specific gap in the literature by linking the source and preparation of each component to surface ch...
Pickering emulsions stabilized by protein assemblies have attracted increasing attention. However, how protein architectures regulate interfacial and bulk properties to determine emulsion stability remains unclear. In this study, fibrils, particulates, and amorphous assemblies of hydrolyzed rice glutelin (HRG) were pre...
Camellia oil is prone to oxidation, while paeonol suffers from poor water solubility and photothermal instability, which limit their coapplication. Although nanocellulose-based Pickering emulsions offer a promising route for codelivery, achieving satisfactory stability at relatively low particle loadings without addi...

To investigate the synergistic co-stabilizers of cellulose nanocrystals (CNCs) and chitin-glucan nanofibers (CGNFs) in Pickering emulsions for curcumin delivery. CNCs were obtained through sulfuric acid hydrolysis, while CGNFs were prepared using a deep eutectic solvent-assisted esterification. CGNFs were characterized...

Pickering emulsions present an effective method for delivering functional oils while addressing their inherent water insolubility. However, the stability of these emulsions can be compromised by complex composition of functional oils and their susceptibility to oxidation. This study developed a composite stabilizer con...
