Carbohydrate Composition with High Fibre via Acid Dextrinization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current carbohydrate compositions, such as dextrins, have limitations including low fibre content, high cost, and complex production processes, which hinder their effectiveness as bulking agents and dietary fibre sources in food, feed, and pharmaceutical applications.
Innovation Solution
A carbohydrate composition with a dextrose equivalence of 20 to 25 and a fibre content of 10 to 90% by weight, produced by treating a starch or starch-containing composition with a moisture content of 6 to 15% and a pH of 1.0 to 3.0 at temperatures between 60°C to 150°C for at least 5 minutes, simplifying the production process and enhancing fibre content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional dextrinization processes are used to produce carbohydrate compositions, then the product has good bulking properties and solubility, but the fibre content is low and production cost is high
Solution Approach 1:
The patent changes key process parameters including using moisture content of 5-20% (higher than conventional processes), pH of 3-6 (less acidic), and temperature of 80-180°C to achieve both high fibre content and reduced production cost while maintaining bulking properties
Solution Approach 2:
The patent performs preliminary acid treatment of starch before dextrinization to modify the starch structure, which facilitates subsequent fibre formation during the dextrinization process, thereby achieving high fibre content without additional processing steps
2Quantity of substance
If starch is heated at high temperatures with very low moisture content to produce dextrin, then the dextrin has good solubility and bulking properties, but the process requires high energy consumption
Solution Approach 1:
The patent uses moisture content of 5-20% (significantly higher than conventional <5%) and temperature of 80-180°C (lower than conventional 120-300°C) to reduce energy consumption while still producing soluble fibre with good bulking properties
Solution Approach 2:
The patent introduces acid as an intermediary catalyst that enables the dextrinization process to proceed at lower temperatures and higher moisture content, thereby reducing energy requirements while maintaining product quality
3Quantity of substance
If complex multi-step processes are used to produce high fibre carbohydrate compositions, then the fibre content increases, but the process complexity and production time increase
Solution Approach 1:
The patent combines acid treatment and dextrinization into a single integrated process step, eliminating the need for separate treatment stages while achieving high fibre content (10-90% by weight), thereby simplifying the overall process
Solution Approach 2:
The patent performs preliminary acid modification of starch that prepares the substrate for fibre formation during dextrinization, allowing fibre content to reach 10-90% through a single process rather than multiple sequential steps
