The aim of this study was to develop a β-carotene-enriched tertiary emulsion (lactoferrin/alginate/ε-poly-L-lysine). Then, its physical stability as well as β-carotene content under external stresses (temperature, pH and ionic strength changes) was evaluated. Furthermore, lipid digestibility and β-carotene bioaccessibility of primary, secondary and tertiary emulsions were determined. Tertiary emulsion underwent a substantial particle size increase up to 13 μm after extreme temperatures, acidic conditions and with salt addition. However, small particle size (0.41 μm) and negative ζ-potential (-43.4 mV) was observed at basic pH. In addition, β-carotene content in tertiary emulsions decreased only 40% when emulsions were subjected at temperatures ≤70ºC, in acidic conditions and below 0.3M NaCl. After in vitro digestion, tertiary emulsion presented higher lipid digestibility (83.59±11.81%) and β-carotene bioaccessibility (70.10±5.26%) compared with primary and secondary emulsions. This study provides knowledge to understand the behaviour of β-carotene-loaded tertiary emulsions under different conditions, valuable for further application in foodstuffs.

Impact of emulsifier nature and concentration on the stability of β-carotene enriched nanoemulsions during in vitro digestion Gasa Falcón, Ariadna; Odriozola Serrano, Isabel; Oms Oliu, Gemma; Martín Belloso, Olga (Royal Society of Chemistry, 2019-01-08)The presence of emulsifiers facilitates the formation of nanoemulsions and helps on their stabilisation. At the same time, behaviour of nanoemulsions along the gastrointestinal tract mainly depend on their composition, ...
Influence of mandarin fiber addition on physico-chemical properties of nanoemulsions containing β-carotene under simulated gastrointestinal digestion conditions Gasa Falcón, Ariadna; Odriozola Serrano, Isabel; Oms Oliu, Gemma; Martín Belloso, Olga (Elsevier, 2017-05-29)There is a lack of knowledge about how soluble fiber used as stabilizer may influence physicochemical properties of nanoemulsions during the lipid digestion process. In this study, different concentrations of mandarin fiber ...
Delivery of β-carotene to the in vitro intestinal barrier using nanoemulsions with lecithin or sodium caseinate as emulsifiers Gasa Falcón, Ariadna; Arranz, Elena; Odriozola Serrano, Isabel; Martín Belloso, Olga; Giblin, Linda (Elsevier, 2021)To increase the intestinal delivery of dietary β-carotene, there is a need to develop nanostructured food systems to encapsulate this fat soluble bioactive. The aim of this study was to evaluate the bioacessibility and ...
