Abstract

We study the phase ordering of colloids suspended in the gel phase of aggregated monoglyceride (MG) and the resulting structures. The nano-sized particles are dispersed in a MG-oil matrix to interact with the lamellar structure of MG to form the paste whose rheological feature can be modified by changing particle concentrations. The paste is metastable and ages into the stable β-crystals of MG. In general, the presence of colloids frustrates the lamellar ordering and leads to a decrease in the enthalpy change on melting and a shift of the gelation point to a lower temperature. © 2011 Elsevier B.V.
