Preparation and use of heat-treated mesomorphic phases in food products

A process for the preparation of a pasteurised or sterile mesomorphic phase of surfactants, comprising the sequential steps of: (a) preparing a premix comprising surfactants and water at a temperature above the Krafft temperature of the surfactant and below the lamellar-cubic transition temperature...

Beschreibung
Zusammenfassung:	A process for the preparation of a pasteurised or sterile mesomorphic phase of surfactants, comprising the sequential steps of: (a) preparing a premix comprising surfactants and water at a temperature above the Krafft temperature of the surfactant and below the lamellar-cubic transition temperature of the surfactant-water mixture; (b) heating the premix at a temperature above the lamellar-cubic transition temperature of the surfactant-water mixture; (c) holding the premix between the Krafft temperature of the surfactant and the lamellar-cubic transition temperature of the surfactant-water mixture, especially with applying high shear, for a sufficient time to allow the mixture to reach a continuous lamellar phase; and (d) cooling the premix to below the Krafft temperature of the surfactants. As an alternative to the shear treatment, the premix can be held at a temperature below the Krafft temperature of the surfactant for at least 0.1 second between steps (b) and (c). The mesomorphic phase thus obtained process can be mixed with further food ingredients to produce a low-fat food product.
