Abstract
Disclosed herein is a method for harvesting amylose host material comprising enzymatically treating starch after the starch has been chemically modified to uniformly insert a steric hindrance substituent.
Claims17
A modified starch gel for use as a food additive, the modified starch gel comprising:
- (a) an amylose portion, which is obtained from at least partially esterifying amylose molecules of the starch;
- and
- (b) an amylodextrin portion, which is obtained from at least partially esterifying amylodextrin molecules, wherein the amylodextrin molecules are formed from enzymatically-liberated, esterified A-chains of amylopectin of the starch,
- wherein the amounts of (a) and (b) and the degree of substitution by esterification in each of (a) and (b) are amounts effective to form a thermo-reversible, meltable gel.

A composition for use as a food additive comprising a modified starch host material complexed with a guest material, wherein the modified starch host material comprises:
- (a) an amylose portion, which is obtained from at least partially esterifying amylose molecules of the starch;
- and
- (b) an amylodextrin portion, which is obtained from at least partially esterifying amylodextrin molecules, wherein the amylodextrin molecules are formed from enzymatically-liberated, esterified A-chains of amylopectin of the starch and which have a helical tube shape with an interior hydrophobic face and an exterior hydrophilic face,
- wherein the amounts of (a) and (b) and the degree of substitution by esterification in each of (a) and (b) are amounts effective to form a thermo-reversible;
- and
- wherein the guest material comprises at least one hydrophobic molecule.
