Non-carbohydrate foaming compositions and methods of making the same

Abstract

A foaming composition includes a powdered carbohydrate-free soluble composition which includes protein particles having a plurality of internal voids containing entrapped pressurized gas. In one form, the foaming composition is produced by subjecting the particles to an external gas pressure exceeding atmospheric pressure prior to or while heating the particles to a temperature of at least the glass transition temperature and then cooling the particles to a temperature below the glass transition temperature prior to or while releasing the external pressure in a manner effective to trap the pressurized gas within the internal voids.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to soluble foaming compositions, and in particular, carbohydrate-free foaming protein compositions which contain pressurized gas. BACKGROUND OF THE INVENTION

[0002] Some conventionally prepared food items include froth or foam. For example, cappuccino, milk shakes, and some soups may have froth or foam. While conventionally prepared food items may be considered preferable by some consumers, other consumers are increasingly demanding the convenience of consumer prepared instant food alternatives. In order to accommodate consumer preferences, manufactures have developed instant food products which give consumers the food products they demand from a convenient instant food product by developing instant food items which have the same or similar characteristics as conventionally prepared food items. One challenge for manufacturers is how to produce a food product having froth or foam from an instant food item.
