Low Swelling Starch Texture Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current starch products used in food processing often result in significant thickness and powderness, failing to provide desired texture modifications and process flexibility, especially under varying conditions such as high and low solids, shear processing, and pH levels.
Innovation Solution
Low swelling starches, achieved through thermal inhibition or chemical crosslinking, are used to modify food textures by providing opacity, mouth-coating, and creaminess without significant thickness, and can substitute for fat, reducing processing times and enhancing process tolerance across different formulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional starch products are used to modify food texture, then thickness and opacity are improved, but powdery-ness and excessive thickness are worsened
Solution Approach 1:
The patent applies parameter changes by modifying the starch structure through controlled swelling inhibition, achieving a swelling volume of 5-15 mL/g. This parameter modification allows the starch to provide desired texture and opacity while minimizing powdery-ness and excessive thickness, directly resolving the technical contradiction.
2Shape
If conventional starches are used to provide texture modification, then opacity and mouth-coating are improved, but processing time is worsened
Solution Approach 1:
The patent employs preliminary action by pre-modifying the starch to have controlled swelling properties before use in food processing. This pre-engineered starch structure requires less processing time to achieve the desired texture and opacity, as the starch is already optimized for rapid functional performance in various food systems.
3Adaptability or versatility
If starches are used across varying processing conditions, then versatility is improved, but consistency of texture is worsened
Solution Approach 1:
The patent utilizes parameter changes by engineering the starch with a specific swelling volume range (5-15 mL/g) that provides optimal performance across varying processing conditions. This parameter optimization ensures that the starch maintains consistent texture and functional properties whether used in high or low solids formulations, under different shear conditions, or across a range of pH levels.
