  • Publication number: 20140178556
    Abstract: An edible composition comprising (a) a cellulose ether selected from (a1) methylcellulose, (a2) hydroxypropyl methylcellulose, and mixtures thereof; (b) a polysaccharide hydrocolloid selected from (b1) alginic acid, alginates and mixtures thereof, and mixtures of (b1) with (b2) a non-ionic and non-acidic polysaccharide hydrocolloid different from cellulose ethers, wherein the total amount of cellulose ether (a) and polysaccharide hydrocolloid (b) ranges from 0.01 to 9% by weight, based on the total weight of the composition, and the weight ratio of cellulose ether (a) to polysaccharide hydrocolloid (b) is within the range of from 1:8 to 8:1, and (c) water. The use of the edible composition to at least partially substitute fat in an edible product such as a dairy product is also described.
