The competitive displacement of a model protein (β-lactoglobulin) by bile salts from air−water and oil−water interfaces is investigated in vitro under duodenal digestion conditions. aim to understand this process so that can be designed control lipid thus improving the nutritional impact foods. Duodenal has been simulated using simplified biological system monitored interfacial measurements atomic force microscopy (AFM). First, properties β-lactoglobulin adsorbed layers at olive were...
This research work deals with the surface behavior of mixed protein/surfactant systems and its relation foam stability. In particular, a novel procedure analysis experimental data is proposed, which provides direct correlation between both phenomena. Accordingly, results presented might constitute promising tool in control stability, has crucial technological application. The characterization performed by studying pressure isotherms systems. qualitative information extracted from curves...
An improved understanding of the behaviour lipids within gastrointestinal tract will facilitate structural design foods that provide specific physiological responses. In this work, we studied influence interfacial characteristics (emulsifier type and surface area) on emulsified a simulated small intestine (duodenum). Pluronic F68-stabilized emulsions were more resistant to lipid digestion than lecithin-stabilized emulsions. Interfacial tension, droplet charge (ζ-potential), microstructure...
It is important to understand how interfacial composition influences the digestion of coated interfaces in order rationally design emulsion based food products with specific profiles. This study has been designed investigate effects gastrointestinal on protein covered interfaces. In this work, we have used a new apparatus fully and assembled at University Granada: OCTOPUS. device enables customised static sequential vitro process single droplet. Physiological conditions each compartment/step...
Understanding the effects of digestion conditions on structure interfacial protein networks is important in order to rationally design food emulsions which can moderate lipid digestion. This study compares effect gastric (pH, temperature, and ionic strength) β-lactoglobulin films at different fluid interfaces: air-water, tetradecane-water, olive oil-water. The experiments have been designed simulate passage into stomach media. Hence, preformed (β-lactoglobulin) exposed establish generic...
Pluronics are being introduced in food research order to delay lipid digestion, with the length of hydrophilic and hydrophobic chains playing an important role rate such a process. Since bile salts play crucial digestion process, aim this work is analyze interactions between Pluronic F127 or F68 salt NaTDC when latter added at physiological concentrations. These studied Pluronic-covered oil-water interface aqueous phase Pluronic-stabilized emulsions. This has been carried out techniques as...
This work investigates the influence of interfacial properties whey protein (WPH) and blue whiting (BPH) hydrolysates on physical stability fish oil-in-water emulsions stabilized with these at pH 2 or 8. Measurements tension dilatational rheology confirmed that is a key factor affecting WPH BPH. WPH, when tested 1 10 mg/mL, showed higher activity 8 compared to BPH 2, despite having lower content. Moreover, 0.1 modulus was significantly than 2. These findings correlate formation smaller oil...
The rheological behavior of β-casein adsorption layers formed at the air−water and tetradecane−water interfaces is studied in detail by means pendant drop tensiometry. First, its briefly summarized both interfaces, experimentally also theoretically. Subsequently, experimental dilatational results obtained for a wide range frequencies are presented interfaces. An interesting dependence with oscillation frequency observed via comparative analysis interfacial elasticity (storage part) viscosity...
The rational design of healthier foods to control fat uptake in the diet is an emerging area research. In order address these dietary issues effectively one requires improved understanding influence food structure on digestion lipids. Despite crucial roles played by interfaces determining stability emulsions and breakdown emulsion digestion, there are few systematic basic studies dealing directly with effects conditions interfacial structures. A major concern attempted manipulation...
Studying interactions between potential anticancer drugs and cell membrane models is of great interest to explore the capability novel in development treatments. Lipid are useful understand cellular discern drug mechanism action. Here, curcumin, as a bioactive natural compound with anti-cancer properties, both healthy cancerous or tumor models, based on Langmuir monolayers, have been studied. The healthy-cell model composed cholesterol 67%, saturated lipid dipalmitoylphosphatidylcholine 33%....
Wind-dispersed pollen grains emitted from vegetation are directly injected into the atmosphere being an important source of natural aerosols globally. These coarse particles can rupture smaller particles, known as subpollen (SPPs), that may act cloud condensation nuclei (CCN) and affect climate. In this study, we characterize investigate ability SPPs 10 Mediterranean-climate types to activate CCN. A continuous flow CCN counter (CCNC) was used measure activation size-selected (80, 100 200 nm...
