Core-shell sweetener particles for sugar reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Food producers face challenges in reducing the sugar content of sugar-coated breakfast cereals without altering their taste, appearance, or physical properties, as sugar coatings are highly visible and contribute significantly to the product's flavor, color, and texture.
Innovation Solution
The development of core-shell sweetener particles, which consist of an edible core and a sweetener layer, allowing for a reduced sugar content while maintaining similar taste and physical properties to traditional sugar coatings, by using a non-sweet core and a concentrated sweetener layer that provides sweetness without increasing the overall sugar content.

Engineering Contradiction Analysis
1Quantity of substance
If traditional sugar coatings are used in breakfast cereals, then taste and appearance are maintained, but sugar content is high
Solution Approach 1:
The sugar coating is segmented into two functional parts: a non-sweet core (providing bulk and structure) and a sweetener layer (providing taste). This segmentation allows the sweetener to be concentrated only where needed for taste, rather than throughout the entire particle, thereby reducing overall sugar content while maintaining flavor.
Solution Approach 2:
The sweetener is applied locally only to the exterior layer of the particle rather than uniformly throughout. The core remains non-sweet, while the outer shell contains the concentrated sweetener that provides taste sensation. This local concentration achieves the desired flavor with minimal total sugar.
2Quantity of substance
If sugar is removed from the coating, then sugar content is reduced, but taste and physical properties deteriorate
Solution Approach 1:
The invention changes the concentration parameter of the sweetener by placing it in a highly concentrated form in the outer layer, while the core uses a different material with different properties. This parameter change allows the sweetener to be present in high concentration at the surface for taste, while the overall average concentration (sugar content) is reduced.
3Quantity of substance
If sugar is removed from the coating, then sugar content is reduced, but physical properties like color, density, and bulk change
Solution Approach 1:
The particle is constructed as a composite structure combining a non-sweet core material with a sweetener-containing outer layer. The core provides the physical properties (bulk, density, color) while the outer layer provides sweetness. This composite approach allows physical properties to be maintained through the core while reducing overall sugar content.
4Quantity of substance
If sugar coating is applied to cereal, then sweetness is achieved, but manufacturing complexity increases
Solution Approach 1:
The core particles are prepared first with the desired physical properties, then the sweetener layer is applied in a subsequent coating step. This preliminary preparation allows the base material to be optimized for physical properties before the sweetening function is added, simplifying the overall manufacturing process compared to creating uniform sugar particles.
