METHOD FOR PREPARING FOAMS AND FOAMS COMPRISING ETHYLCELLULOSE PARTICLES

摘要

A method for preparation of an aqueous foam, a method for preparation of an aerated food product, an aqueous foam comprising ethylcellulose particles, food products comprising the aqueous foam, ethylcellulose particles and use of ethylcellulose particles are disclosed. The method for preparation of an aqueous foam comprises the steps: a) dissolving ethylcellulose in an organic solvent which is miscible in water; b) addition of water to the mixture of step a), wherein the amount of water is at a weight ratio between 10:1 and 1:2 based on the organic solvent; c) evaporating organic solvent and water to a concentration of ethylcellulose of at least 1% by weight; d) additon of an acid to a pH of 4 or lower, or addition of a water-soluble salt to an ionic strength of at least 20 millimolar; or addition of a combination of acid and water-soluble salt; e) introduction of gas bubbles to the composition of step d) to create a foam.
