Sugar Coating Crystallinity for Reduced Hygroscopicity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pre-sweetened breakfast cereals face challenges in reducing sucrose content while maintaining desirable product traits such as texture, flavor, and processing efficiency, as replacing sucrose with non-sucrose sweeteners like corn syrup increases hygroscopicity and stickiness, leading to clumping and reduced bowl life.
Innovation Solution
A sugar coating composition is developed that includes a combination of crystalline sucrose and non-sucrose soluble solids, where the sucrose ratio is optimized to achieve high sucrose crystallinity and reduced hygroscopicity, using a formula that balances sucrose and non-sucrose content to maintain product quality and texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If sucrose is replaced with non-sucrose sweeteners like corn syrup to reduce cost, then manufacturing cost is reduced, but the sugar coating becomes more hygroscopic and sticky
Solution Approach 1:
The patent changes the physical state parameter of sucrose from dissolved to crystalline form. By controlling crystallization during the drying process, the coating maintains reduced sucrose content while the crystalline structure reduces hygroscopicity and stickiness compared to amorphous or dissolved sugar forms
Solution Approach 2:
The patent creates a composite coating system combining multiple components: non-sucrose sweeteners (corn syrup, corn syrup solids), crystalline sucrose, and optional additives like polydextrose or sugar alcohols. This composite approach allows cost reduction through non-sucrose sweeteners while crystalline sucrose provides structural benefits that reduce stickiness
2Quantity of substance
If sucrose content is reduced to lower cost, then manufacturing cost is reduced, but processing efficiency and handling ease deteriorate due to increased stickiness
Solution Approach 1:
The patent controls the crystallization parameter during drying to produce a coating with reduced stickiness. The crystalline structure of sucrose in the coating improves flow properties and reduces clumping during processing, maintaining ease of operation despite reduced sucrose content
Solution Approach 2:
The patent uses crystalline sucrose as a model structure that replicates the desirable low-stickiness properties of traditional high-sucrose coatings. The crystalline form serves as a template that maintains processing efficiency while allowing substitution with cheaper non-sucrose sweeteners
3Quantity of substance
If non-sucrose soluble solids are increased to reduce sucrose content, then cost is reduced, but moisture absorption increases leading to reduced bowl life
Solution Approach 1:
The patent changes the physical state of sucrose to crystalline form, which has lower hygroscopicity than amorphous sugars. This parameter change reduces moisture absorption from the environment, extending bowl life even when non-sucrose soluble solids are increased to reduce cost
Solution Approach 2:
Crystalline sucrose acts as an intermediary component that mediates between the hygroscopic non-sucrose sweeteners and the environment. The crystalline structure provides a barrier that reduces moisture uptake, protecting the overall coating from excessive moisture absorption and extending product freshness
