Comparison of Test Emulsions

[0098]The effectiveness of the starch emulsifier products of the present invention in emulsifying a high oil load / emulsifier ratio and in maintaining a stable emulsion viscosity were examined as set forth below in TABLE 1. All samples below in TABLE 1 were prepared using one of two methods: (1) OSA-derivatized dispersed phase (DP) emulsifiers, in which (a) granular starch was (b) slurried in aqueous solution; (c) solubilized via jet-cooking; (d) in some step subsequent to solubilization, derivatized with OSA; and (e) spray-dried; or (2) OSA-derivatized granular emulsifiers, in which (a) granular starch was (b) slurried in aqueous solution; (c) derivatized with OSA; (d) in some step subsequent to derivatization with OSA, solubilized via jet cooking; and (e) spray-dried.

High Oil Load Emulsion Performance

[0100]High oil load (24%) performance of emulsifiers of the invention prepared using various OSA-derivatized dispersed phase emulsifiers derived from various starch sources and subject to high oil load (24%) emulsion conditions were assessed. Samples were prepared by slurrying 8 kg (anhydrous basis) starch in 12 liters tap water. This slurry was then jet cooked, using a Hydroheater (Hydro-Thermal Corporation, Milwaukee, Wis.) cooking chamber at approximately 154° C. (310° F.), resulting in a 30% solids jet cooked starch dispersion (after slight dilution—one waxy corn starch cook was run at 24.5% solids).

[0101]The cook was divided into three 8 liter stainless steel beakers, and placed in a hot water bath at 90° C. To each was added 0.075% concentrated HCl (on as-is starch weight). The funnel viscosity was tracked over time until the desired range was reached.

[0102]The OSA derivatization reaction was carried out on these dispersions in stainless steel...

Abstract

The present invention relates to a starch emulsifier product prepared by sufficiently solubilizing a starch and subsequently sufficiently derivatizing the sufficiently solubilized starch product, in one embodiment by reacting the sufficiently solubilized starch with an alkenyl succinic anhydride. Such starch emulsifier products are useful as emulsifying and / or encapsulating agents, particularly in systems where high load and retention of the active ingredient, low surface oil exposure, and excellent oxidation resistance is desired.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates to the preparation of a novel emulsifier; emulsions prepared with the emulsifier; and products prepared utilizing the emulsifier.[0002]Half-ester starch derivatives may be created by reacting starch and a substituted dicarboxylic acid anhydride so as to form alkenyl succinic anhydride starch derivatives. Native starch granules are insoluble in cold water. When native starch granules are dispersed in water and heated, however, they become hydrated and swell. With continued heating, shear, or conditions of extreme pH, the granules fragment and the starch molecules are dispersed in the water, i.e., solubilized, resulting in a nongranular, dispersed starch.BRIEF SUMMARY OF THE INVENTION[0003]In one embodiment, the invention comprises an emulsifier product that is a starch half ester of an alkenyl succinic anhydride. The starch half ester of an alkenyl succinic anhydride has a water fluidity of no more than 75, is prepared by a disp...
