Abstract
Abstract The invention pertains to an edible dispersion and a process for making same, comprising an aqueous and a fat phase, the aqueous phase being gel-forming and comprising carrageenan and a cation of a type and in a concentration effective to cause the aqueous phase to have a transition midpoint temperature of below 50° C. Dispersion according to the invention can be advantageously applied in water-in-oil spreads, mayonnaise, salad dressings, etc.

Claim 1
Independent Claim
126 words
Edible dispersion which comprises 15-90 wt.% of a dispersed aqueous phase and 10-85 wt.% of a continuous fat phase, the composition constituting the aqueous phase being a gel-forming composition comprising carrageenan and containing a cation (A) selected from the group consisting of potassium, calcium, magnesium and mixtures thereof in a concentration effective to cause the gel-forming composition to have a transition midpoint temperature in the range of 10°-45° C., the carrageenan being selected from the group consisting of kappa-carrageenan, iota-carrageenan and a mixture thereof, said carrageenan present in the amount of 0.1-10 parts per 100 parts by weight of any water included within said dispersion, said gel-forming composition capable of forming a gel having a yield stress of at least 0.5 kN/m 2 at 5° C.
Claim 2
