Process for preparation of a foamed composition by hydrodynamic cavitation

摘要

The invention relates to a process for preparation of a foamed composition and a foamed composition prepared thereby. The invention more particularly relates to food compositions comprising gas bubbles that remain entrained for long periods of time in the compositions.
According to the first aspect of the present invention there is provided a process to prepare a foamed composition comprising a liquid, gas bubbles dispersed therein and a foam stabilizer selected from di or multi block surface active polymers, surface active proteins, surface active colloidal particles and combinations there of, wherein the process comprises a step of foaming by hydrodynamic cavitation.
