Aspic Food Contouring via Negative Mold and Vacuum Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing food-in-aspic dishes cannot impart a specific contour to the finished product due to the opaque nature of aspic, which hinders visibility of ingredients and aesthetic appeal.
Innovation Solution
A method involving a two-stage boiling process where the aspic liquefies to assume the shape of a negative mold, followed by vacuum packaging and weighting to maintain the contour, allowing for complex shapes and enhanced visual presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If aspic is used in traditional opaque packaging, then hygienic storage and transportation are ensured, but the visibility of individual ingredients is lost which is essential for purchase decisions
Solution Approach 1:
The packaging film is made transparent instead of opaque, allowing light to pass through and enabling customers to see the ingredients inside. This transparency serves as a visual indicator while maintaining the protective function of the packaging.
2Shape
If aspic is delivered in transparent packaging, then visibility of ingredients is improved, but the aspic cannot be given a specific contour due to its liquid-to-solid phase change
Solution Approach 1:
A negative mold with the desired contour is prepared in advance before the aspic is poured in. The mold is placed in the packaging, then the liquid aspic is poured over the food, ensuring the aspic will take the desired shape when it solidifies.
Solution Approach 2:
A negative mold is introduced as an intermediary object between the liquid aspic and the final solid form. The mold acts as a template that guides the aspic into the desired contour, and is later removed after the aspic solidifies.
3Reliability
If vacuum packaging is applied to aspic food, then shelf life is extended and packaging takes on the contour, but air expansion during boiling could burst the packaging
Solution Approach 1:
The boiling process is divided into two separate stages: first boiling the food with aspic to cook it, then after cooling and vacuum packaging, a second brief boiling to melt and reshape the aspic. This periodic approach allows the packaging to be vacuum-sealed when cool and intact, then briefly exposed to heat for reshaping without prolonged exposure that would cause air expansion and bursting.
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
Enables the creation of aspic food with a desired contour, improving visibility and aesthetic appeal while ensuring hygienic storage and transportation through transparent packaging and vacuum sealing.
Implementation Method 1
the aspic liquefies when boiling and that the food thus assumes the contour of the negative shape
Implementation Method 2
after the aspic has cooled the entire food solidifies and takes on the contour of the negative shape
Implementation Method 3
The vacuum packaging ensures that no air remains inside the packaging, which could expand during the second boil and possibly burst the packaging

AI summary
Preparing a foodstuff-in-aspic dish, comprises placing foodstuffs into a bowl, filling the bowl with liquid aspic, boiling everything in the bowl, removing the dish (1) after solidification of the aspic, packing, inserting the packed dish in a negative mold (2), heating for a second time, preferably boiling, where the packed dish remains in the negative mold until the resolidification of the aspic.
