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.
Abstract: Disclosed is a nucleotide sequence encoding an effective portion of a class A starch branching enzyme (SBE) obtainable from potato plants, or a functional equivalent thereof, together with, inter alia, a corresponding polypeptide, a method of altering the characteristics of a plant, a plant having altered characteristics; and starch, particularly starch obtained from a potato plant, having novel properties.
