An overview on preparation of emulsion-filled gels and emulsion particulate gels

Conclusions: Oil droplets depending on their interfacial composition act as either active or inactive fillers in an emulsion-filled gel. Actively functioning oil droplets can increase gel modulus, whereas, inactive oil droplets typically weaken gel texture. Interactions between surfactants and polymers, which influences filler affinity to gel matrix, have significant consequences on emulsion gel rheology. For protein-based emulsion gels, surfactant may also influence proteins unfolding and aggregation.In situ gelation of an emulsion can be triggered by environmental factors such as temperature changes during processing and storage or by physiological stimuli such as acidic pH in the stomach. The clustering approach, which is used to form emulsion particulate gels may be utilized to control digestibility of lipids in the gastrointestinal tract. The capability of encapsulating two or more different lipophilic components within a single delivery system may be achieved via heteroaggregation technique.Graphical abstract
