Method for improving the functional properties of a globular protein, protein thus prepared, use thereof and products containing the protein

摘要

The invention relates to a method for improving the functional properties of globular proteins, comprising the steps of providing a solution of one or more globular proteins, in which solution the protein(s) is/are at least partially aggregated in fibrils; and performing one or more of the following steps in random order: increasing the pH; increasing the salt concentration; concentrating the solution; and changing the solvent quality of the solution. Preferably, the solution of the one or more globular protein is provided by heating at a low pH or the addition of a denaturing agent. The invention also relates to the protein additive thus obtained, to the use thereof for food and non-food applications and to the food and non-food products containing the protein additive.
