Resistant Starch-Hydrocolloid Blends for Digestive Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods do not effectively address the interaction between resistant starches and hydrocolloids, nor do they explore the resulting nutritional or functional benefits in food systems.
Innovation Solution
The development of stable starch products comprising resistant starch and hydrocolloids, where the starch and hydrocolloid are interacted to enhance resistance to α-amylase digestion, dietary fiber content, and functional properties such as emulsion stability and water swelling capacity, by forming a dispersion in water and drying with optional heating to strengthen the interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resistant starch is used alone, then resistance to α-amylase digestion is improved, but functional properties like emulsion stability and water swelling capacity are insufficient
Solution Approach 1:
The patent combines resistant starch with hydrocolloids (such as xanthan gum, guar gum, carrageenan, or alginate) to create composite starch products. This composite approach allows the product to maintain the resistant starch's digestion resistance while gaining the hydrocolloid's functional properties including emulsion stability, water swelling capacity, and texture modification capabilities, thereby resolving the contradiction between digestive resistance and functional versatility
2Ease of manufacture
If starch and hydrocolloid are mixed without interaction treatment, then manufacturing simplicity is maintained, but the stability and functional enhancement are insufficient
Solution Approach 1:
The patent employs parameter changes by controlling pH levels and temperature conditions during the interaction process between resistant starch and hydrocolloids. By adjusting these parameters, the starch and hydrocolloid form stable complexes with enhanced functional properties. This approach maintains relative manufacturing simplicity while achieving improved product stability through controlled chemical-physical interactions
