Patent ID: 7829600

Claim:
An emulsifier product comprising: A starch half ester of an alkenyl succinic anhydride, wherein the starch half ester of the alkenyl succinic anhydride has a water fluidity of not more than 75 at a 8.06% solids level, wherein the starch half ester of the alkenyl succinic anhydride is prepared by a dispersed phase process, and wherein, when the starch half ester of an alkenyl succinic anhydride is used to prepare a test oil-in-water emulsion, the test oil-in-water emulsion is characterized by at least the following: a) no more than about 5% of the oil particles of the emulsion greater than 1 μm after 24 hours at 57 C as assessed by polarization intensity differential plus elastic light scattering; and b) a Brookfield viscosity of the emulsion of less than about 2000 cps after about one week of storage at 5 C, as assessed by Brookfield Programmable DV-1 Viscometer; and wherein the test oil-in-water emulsion is prepared with the starch half ester of an alkenyl succinic anhydride as a sole emulsifier; at a w/w ratio of the starch half ester of an alkenyl succinic anhydride:oil of 1:4; at a 20% by weight oil load; and with the oil consisting of 48% 1× orange oil; 12% 5× orange oil; and 40% ester gum weight/weight.
