Candy Coating for Frozen Fruit Using an Oil Moisture Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The migration of moisture from high-moisture fruits to candy coatings compromises the integrity, crispness, and longevity of the coating, affecting its structural and aesthetic appeal.
Innovation Solution
Applying a thin layer of hydrophobic oil between the frozen fruit and candy coating to act as a moisture barrier, enhancing adhesion and providing a protective shield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If frozen fruit is coated directly with candy coating, then the coating process is simple, but moisture migrates from the fruit to the candy coating compromising integrity and crispness
Solution Approach 1:
A hydrophobic oil layer is applied as an intermediary substance between the frozen fruit surface and the candy coating. This oil layer acts as a moisture barrier that prevents water migration from the high-moisture fruit to the sugar-based candy coating, thereby maintaining coating integrity while allowing the coating process to proceed efficiently
2Reliability
If a moisture barrier is applied to prevent moisture migration, then candy coating integrity is maintained, but the coating process becomes more complex
Solution Approach 1:
The solution changes the physical-chemical parameters of the fruit surface by applying a hydrophobic oil layer that alters the surface properties. This creates a water-repellent barrier that naturally prevents moisture migration without requiring complex coating equipment or multi-step processes, thereby maintaining simplicity while ensuring integrity
3Adaptability or versatility
If frozen fruit with high moisture content is coated with sugar-based candy, then the coating provides flavor and aesthetic appeal, but moisture dissolves or weakens the candy shell
Solution Approach 1:
The hydrophobic oil layer serves as a protective intermediary that blocks the path of moisture molecules from the fruit interior to the candy coating. This prevents the sugar-based candy shell from absorbing moisture and dissolving, thereby preserving both the structural strength and the flavor-aesthetic properties of the coating
4Reliability
If oil layer is applied as moisture barrier, then moisture migration is prevented and adhesion is improved, but additional processing step is required
Solution Approach 1:
The hydrophobic oil layer is applied as a preliminary treatment step before the candy coating is applied. This preliminary action of oil application creates a permanent moisture barrier that remains in place throughout subsequent coating and storage, preventing future moisture migration issues and eliminating the need for additional protective measures during the candy coating process
