Isomalt Coating Transparency Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing confectionery products with hard, transparent coatings are not stable under varying environmental conditions and lack the combination of crunchiness and transparency, as they often contain opacifying agents or are prone to graining, which reduces transparency.
Innovation Solution
A hard, crunchy, transparent coating is achieved using isomalt syrup for over 90% and isomalt powder for less than 3% by weight, without opacifying agents like titanium dioxide, calcium carbonate, or starch, which maintains its properties and prevents graining, ensuring stability and visibility of colored centers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional hard transparent coatings are used, then transparency is achieved, but stability under environmental conditions deteriorates
Solution Approach 1:
The patent changes the chemical composition parameters of the coating by using isomalt syrup (over 90% by weight) and isomalt powder (less than 3% by weight) instead of traditional coating materials. This parameter change enables the coating to maintain both transparency and stability under varying environmental conditions including temperature and humidity variations.
Solution Approach 2:
The patent employs a composite coating system combining isomalt syrup and isomalt powder in specific proportions. This composite material approach creates a coating that achieves both optical properties (transparency) and mechanical/chemical stability, resolving the contradiction between transparency and environmental stability.
2Strength
If opacifying agents are added to achieve hard coating, then coating hardness is improved, but transparency deteriorates
Solution Approach 1:
The patent extracts and eliminates opacifying agents (such as titanium dioxide, calcium carbonate, or starch) from the coating formulation. By removing these materials that provide hardness but block light, the patent achieves a coating that is both hard and transparent through the use of isomalt-based materials only.
Solution Approach 2:
The patent changes the material composition by excluding opacifying agents and using only isomalt syrup and powder. This parameter change in composition enables the coating to achieve hardness through the crystalline structure of isomalt while maintaining transparency.
3Ease of manufacture
If conventional coating materials are used, then coating formation is achieved, but graining occurs reducing transparency
Solution Approach 1:
The patent changes the material parameters by using isomalt syrup (over 90%) and isomalt powder (less than 3%) in controlled proportions. This specific composition prevents graining during coating formation while maintaining transparency, as the isomalt materials form a uniform crystalline structure without the graining defects associated with conventional coating materials.
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
The coating remains transparent and crunchy for longer, maintaining its organoleptic properties under different environmental conditions, with increased stability and visibility of colored centers through the transparent coating.
Implementation Method 1
