Protein coated gas microbubbles

摘要

The invention relates to a process for the preparation of a food product comprising the steps of: (a) preparing a mixture comprising protein and water; (b) adjusting the pH of the mixture to a value within the range of 2.0-11.0; (c) pre-incubating the mixture; (d) subjecting the mixture to a sonication treatment or a high shear mixing treatment; (e) optionally, separating the product of step (d) in a fraction rich in gas microbubbles and a fraction poor in gas microbubbles; (f) drying the mixture and/or fraction comprising protein coated gas microbubbles until dried protein coated gas microbubbles are obtained; (g) using the dried protein coated gas microbubbles in part or in whole as a food ingredient and (h) finishing the preparation of the food product.
