  • Preparation of heat-treated mesomorphic phases in food products
    Patent number: 5939128
    Abstract: 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).
