Aewx Corn Starch Retrogradation for Food Texture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corn starches lack the desired rheological properties to provide differentiated textures in food compositions, particularly in terms of viscosity and retrogradation.
Innovation Solution
The use of unmodified aewx corn starch, which has a specific genetic composition with three copies of the recessive waxy gene and two copies of the recessive amylose extender gene, resulting in a starch with unique amylopectin structure and enhanced retrogradation properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If waxy corn starch is used, then amylose content is reduced, but retrogradation and firmness development are limited
Solution Approach 1:
The patent applies parameter changes by modifying the genetic composition of corn starch to achieve specific rheological properties. The aewx corn starch has a defined genetic makeup (three copies of recessive waxy gene and two copies of recessive amylose extender gene) that produces unique amylopectin structure with longer branch chains, enabling enhanced retrogradation and firmness development while maintaining waxy starch characteristics.
Solution Approach 2:
The patent creates a composite starch material with specific genetic traits (aewx corn starch) that combines waxy starch properties with enhanced retrogradation capabilities. This composite approach allows the starch to provide both immediate textural properties and time-dependent firmness development, resolving the contradiction between waxy characteristics and retrogradation potential.
2Shape
If amylose extender gene dosage is increased, then amylopectin branch chain length increases, but viscosity development is reduced
Solution Approach 1:
The patent optimizes the genetic parameters of corn starch by controlling the dosage of waxy and amylose extender genes. The specific combination of three waxy gene copies and two amylose extender gene copies creates an optimal balance where amylopectin branch chains are sufficiently long to provide structural integrity, while the overall starch composition maintains adequate viscosity development when gelatinized.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The unmodified aewx corn starch provides substantial viscosity and reversible firmness to aqueous compositions, allowing for the creation of firmer compositions over time, which is uncommon in waxy starches.
Implementation Method 1
the unmodified aewx corn starch dispersed in water retrogrades to form firmer compositions than a similar dispersions using waxy corn starch

AI summary
The technology disclosed in this specification is directed to starch from a hybrid corn plant. The starch is called in this specification an aewx corn starch or is described by the amylopectin fine structure of the starch. The starch had differentiated functionality compared to common waxy corn starch. Also disclosed in this specification are uses of unmodified aewx corn as a texturizer in, alone or in combination with a second ingredient in food composition.
