    Interfacial activity and interfacial shear rheology of native ß-lactoglobulin monomers and their heat-induced fibers

    Jung, Jin-Mi ; Zeynel Gunes, Deniz ; Mezzenga, Raffaele

    In: Langmuir, 2010, vol. 26, no. 19, p. 15366–15375

    Interfacial properties of native β-lactoglobulin monomers and their heat-induced fibers, of two different lengths, were investigated at pH 2, through surface tension measurements at water−air and water−oil interfaces and interfacial shear rheology at the water−oil interface. The applied heat treatment generates a mixed system of fibers with unconverted monomers and hydrolyzed peptides. The...

    Structural and rheological investigation of Fd3m inverse micellar cubic phases

    Pouzot, Matthieu ; Mezzenga, Raffaele ; Leser, Martin E. ; Sagalowicz, Laurent ; Guillot, Samuel ; Glatter, Otto

    In: Langmuir, 2007, vol. 23, no. 19, p. 9618-9628

    In the present study we demonstrate that a bulk inverse micellar cubic phase of Fd3m structure can be obtained by adding a hydrophobic component, such as the food-grade limonene, to the binary system monolinolein/water in a well-defined composition. The Fd3m structure studied in this work had a very slow kinetics of formation, as a consequence of partitioning of water...
