In this study, we used large, rigid, and hydrophilic zein-propylene glycol alginate composite particles (ZPCPs) and small, soft, and hydrophobic whey protein microgel (WPM) particles to synergistically stabilize a Pickering emulsion for delivery of β-carotene. The photothermal stability and storage stability of β-carotene were improved with the combined use of different particles. Microstructural observations showed that ZPCPs were effectively adsorbed at the oil/water interface despite the substantial interparticle gaps. WPM particles could swell and stretch on the interface due to their deformable structure, thereby forming an interfacial layer of flattened particles to cover a large surface area. The interfacial structure and macroscopic properties of Pickering emulsions were modulated by adjusting the mass ratio and addition sequence of different particles. The combination of ZPCPs and WPM delayed the lipolysis during gastrointestinal digestion. Through controlling the composition of the complex interface, the free fatty acid (FFA) release rate of Pickering emulsions in the small intestinal phase was reduced from 15.64% to 9.03%. When ZPCPs were used as the inner layer and WPM as the outer layer and the mass ratio of ZPCPs to WPM was 4 : 1, the Pickering emulsion showed the best stability and β-carotene bioaccessibility. The Pickering emulsion with particle-particle complex interfaces could be applied in foods and pharmaceuticals for the purpose of enhanced stability, delayed lipolysis or sustained nutrient release.

In this study, we explored the application of lactoferrin-(-)-epigallocatechin-3-gallate (LF-EGCG) complex with rapeseed, soybean, walnut, peanut and sesame oil for the preparation of Pickering emulsions and its spray-dried microcapsules. Spectroscopy and molecular docking revealed that LF-EGCG binds via hydrogen bonds, hydrophobic interactions, and van der Waals forces. Structural analysis demonstrated that 0.

Pickering emulsions (PEs), where water-in-oil (w/o) droplets are stabilized by nanoparticles (NPs), offer a promising platform for biocatalysis by providing a large interfacial area crucial for efficient substrate conversion. While several lipase catalyzed reactions in PEs have been demonstrated, the exact interfacial structure is unknown. This study focuses on the interfacial network formed by NPs and lipase (CRL) at the octanol/water-interface by varying pH and NP charge.

Cultivating fat for edible tissue presents significant challenges, due to the high costs associated with growth and differentiation factors, alongside the poor viability of adipocytes resulting from cell clustering. Additionally, there is a gap in research regarding the rapid accumulation of fats within cells. To that end, this study presents the development of a biodegradable soy protein colloidosome system for an efficient application: direct delivery of oils into bovine satellite cells, enabling rapid intracellular fat accumulation without the need for adipogenic differentiation.

Fresh walnuts are prone to moisture loss and spoilage after harvest, leading to reduced appearance and sensory quality. In this study, a multifunctional chitosan (CS)-based film was fabricated by incorporating a bacterial cellulose/oregano essential oil (BC/OEO) Pickering emulsion, with hydrogen bonding promoting cohesive matrix integration. The film's physicochemical properties, along with its antimicrobial and antioxidant activities, were systematically evaluated.

Environmentally friendly food packaging has emerged as a viable strategy to replace traditional plastic films. In this study, eugenol Pickering emulsion was constructed with konjac glucomannan (KGM) and tragacanth gum (GT) as stabilizers, and was introduced into the KGM/chitosan (CS) composite film by electrostatic action to develop a new type of active packaging film. Interfacial characterization revealed optimal emulsion stability at a 1:5 KGM-to-GT mass ratio.
