Oligosaccharide Compositions for Sugar Substitution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current low-calorie sweeteners fail to adequately replace sugar in food and beverages due to unpleasant tastes, inability to mimic sugar's functional roles, and gastrointestinal tolerance issues.
Innovation Solution
Development of novel compositions comprising mixtures of oligosaccharides, specifically cello-oligosaccharides, xylo-oligosaccharides, mixed-linkage glucan oligosaccharides, manno-oligosaccharides, and xyloglucan oligosaccharides, which are used as sugar substitutes in foodstuffs, cosmetics, and nutraceuticals, and are produced through enzymatic processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional low-calorie sweeteners are used to substitute sugar, then caloric intake is reduced, but unpleasant tastes and gastrointestinal tolerance issues occur
Solution Approach 1:
The patent uses composite oligosaccharide materials comprising multiple types (cello-oligosaccharides, xylo-oligosaccharides, mannose-containing oligosaccharides, and galactose-containing oligosaccharides) to create a synergistic sweetening composition that mimics sugar's functional properties while avoiding the harmful effects of single-component sweeteners
Solution Approach 2:
The patent optimizes the degree of polymerization parameters of the oligosaccharides (specifically DP 2-6 for cello-oligosaccharides, DP 2-12 for xylo-oligosaccharides, and DP 2-12 for mannose and galactose-containing oligosaccharides) to achieve optimal balance between sweetness, bulk, and gastrointestinal tolerance
2Quantity of substance
If bulking sweeteners are used to mimic the physical properties of sugar, then bulk and texture are improved, but gastrointestinal tolerance deteriorates
Solution Approach 1:
The patent carefully controls the degree of polymerization of oligosaccharides to be low (DP 2-12), which provides adequate bulk and texture-mimicking properties while remaining within gastrointestinal tolerance limits, unlike higher molecular weight bulking agents
Solution Approach 2:
The combination of four different oligosaccharide types creates a composite material that distributes the bulking function across multiple components, each contributing to overall bulk while maintaining individual gastrointestinal compatibility
3Ease of manufacture
If sweeteners are designed to mimic sweetness of sugar, then sweetness is achieved, but ability to mimic broad functional roles of sugar deteriorates
Solution Approach 1:
The oligosaccharide composition is designed to perform multiple functions simultaneously: providing sweetness, adding bulk, modulating texture, providing structure, acting as a preservative, and enabling color and flavor development through caramelization and Maillard reactions, thereby replacing sugar's comprehensive functional roles
Solution Approach 2:
Different oligosaccharide types contribute different functional properties to the composite material, creating a multi-functional substitute that can replace sugar's diverse roles in food systems
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
These oligosaccharide compositions offer improved and tunable properties, enabling them to serve as effective sugar substitutes that mimic the functional roles of sugar, while also enhancing gastrointestinal tolerance.
Implementation Method 1
These processes can be used to create different formulations comprising different types and amounts of the one or more oligosaccharides and the one or more polysaccharides using enzymatic processes
