Abstract
Modified starches useful for emulsifying industrial products, especially foods and beverages containing flavor oils, are prepared by enzymatic degradation of the 1,4-alpha-D-glucosidic linkages from the non-reducing ends of a starch molecule, preferably employing beta-amylase, which may be carried out before or after the preparation of a starch derivative containing a hydrophobic group or both hydrophilic and hydrophobic substituent groups. The enzymatic degradation provides a starch emulsifier whose emulsions are characterized by improved shelf stability, which emulsifier may be used as a replacement for gum arabic and in other industrial applications.
Claims5
A food product, comprising an emulsion characterized by improved stability and resistance to oiling and gelling during storage, wherein the emulsion is prepared employing a starch derivative containing a hydrophobic group or both a hydrophilic group and a hydrophobic group, of which up to 70%, by weight, has been degraded to maltose by reaction with an exo-enzyme capable of cleaving 1,4-alpha-D-glucosidic linkages from non-reducing ends of starch but incapable of cleaving 1,6-alpha-D-glucosidic linkages of starch.
A beverage flavor concentrate, comprising an emulsion characterized by improved stability and resistance to oiling and gelling during storage, wherein the emulsion is prepared employing a starch derivative containing a hydrophobic group or both a hydrophilic group and a hydrophic group, of which up to 70%, by weight, has been degraded to maltose by reaction with an exo-enzyme capable of cleaving 1,4-alpha-D-glucosidic linkages from non-reducing ends of starch but incapable of cleaving 1,6-alpha-D-glucosidic linkages of starch.
A flavoring agent, comprising an emulsion characterized by improved stability and resistance to oiling and gelling during storage, wherein the emulsion is prepared employing a starch derivative containing a hydrophobic group or both a hydrophilic group and a hydrophic group, of which up to 70%, by weight, has been degraded to maltose by reaction with an exo-enzyme capable of cleaving 1,4-alpha-D-glucosidic linkages from non-reducing ends of starch but incapable of cleaving 1,6-alpha-D-glucosidic linkages of starch.
