Aqueous Egg Dye Composition with Acid Binder for Natural Color Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for dyeing eggs with natural dyes, such as vegetable and animal dyes, fail to achieve adequate and long-lasting color due to surface reactions that prevent the dyes from adhering sufficiently to the eggshell, regardless of the egg's condition.
Innovation Solution
An aqueous egg dye composition comprising a binder, an inorganic or organic acid, and natural dyes, with a pH range of 2.5 to 5.5, which includes preferred natural dyes like fruit juice concentrates, curcumin, and chlorophyllins, and a binder like dextrin, applied to a flat material like a fleece for effective color transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If natural dyes are used to color eggs, then the coloring is more natural and safe, but the color adhesion and intensity are insufficient
Solution Approach 1:
The patent adjusts the pH parameter of the dyeing solution to a specific range (2.5-5.5) to optimize the binding between natural dyes and eggshell. This parameter change enables natural dyes to achieve sufficient adhesion and color intensity without requiring synthetic dye chemicals, resolving the contradiction between natural safety and coloring effectiveness.
Solution Approach 2:
The patent introduces acid substances as intermediaries that facilitate the binding between natural dyes and eggshell surface. The acid modifies the surface properties of the eggshell and enhances the affinity of natural dyes, enabling adequate color transfer and adhesion while maintaining the natural composition of the dyeing system.
2Productivity
If eggs are cooked in the dye bath, then cooking and coloring are done simultaneously, but natural dyes still fail to adhere sufficiently
Solution Approach 1:
The patent changes the chemical parameter (pH) of the dyeing solution to create optimal conditions for natural dye adhesion. This allows the dyeing process to be effective whether eggs are cooked or not, maintaining process flexibility while ensuring reliable color adhesion through the modified chemical environment rather than relying solely on thermal processing.
3Quantity of substance
If alcohol-based colors with carriers are used, then intensive and water-resistant color effects are achieved, but natural dyes cannot be transferred to eggshells with sufficient coloring power
Solution Approach 1:
The patent changes the pH parameter to a range (2.5-5.5) that is specifically optimized for natural dye performance. This parameter adjustment creates a chemical environment where natural dyes can achieve intensive coloring power comparable to or exceeding alcohol-based systems, while maintaining compatibility with natural and water-based formulations.
Solution Approach 2:
The patent replaces the need for alcohol-based carriers and complex transfer mechanisms with a simplified aqueous system. By adjusting the pH parameter, the system achieves direct and effective color transfer to eggshells without requiring alcohol solvents or carrier materials, eliminating the complexity of the transfer mechanism while maintaining or improving color intensity.
