Botanical Stabilizers Prevent Synthetic Beverage Color Fading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Synthetic colors in beverages are prone to fading, particularly in low oxygen environments, where anti-oxidants are ineffective and can even worsen the issue, leading to aesthetic problems and decreased consumer acceptance.
Innovation Solution
A food coloring composition comprising a synthetic color and a botanically derived color stabilizer with a C6-C3 phenylpropenoic carbonyl structure, such as rosmarinic acid or chlorogenic acid, which prevents light-induced fading by including these compounds in the beverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-oxidants are added to prevent color fading, then oxidation protection is improved, but color stability worsens in low oxygen environments where they are ineffective or worsen fading
Solution Approach 1:
The patent changes the chemical mechanism from oxidation-based protection (anti-oxidants) to reduction-based protection (anti-reducing agents). This parameter change in the protective mechanism allows the composition to effectively address color fading in low oxygen environments where traditional anti-oxidants fail.
Solution Approach 2:
The patent introduces anti-reducing agents as intermediary substances that specifically counteract reducing agents causing color fading. These intermediaries (anti-reducing agents) mediate between the synthetic color and the harmful reducing environment, providing protection without the limitations of anti-oxidants.
2Illumination intensity
If synthetic colors are used in beverages, then color intensity is improved, but color fading worsens under UV light and storage conditions
Solution Approach 1:
The patent creates a composite color composition by combining synthetic colors with anti-reducing agents. This composite material maintains the vibrant color intensity of synthetic dyes while adding protective functionality to prevent fading from both oxidation and reduction, as well as UV-induced degradation.
Solution Approach 2:
The patent applies beforehand cushioning by incorporating anti-reducing agents into the beverage formulation prior to exposure to degrading conditions. This preemptive protection cushions against color fading from reducing agents, UV light, and storage conditions before they can cause significant deterioration.
3Adaptability or versatility
If natural colors are used, then consumer acceptance is improved, but color stability worsens due to oxidative fading mechanisms
Solution Approach 1:
The patent creates a universal protection system using anti-reducing agents that can protect both natural and synthetic colors. This multi-functional approach allows the same protective mechanism to work across different color types, addressing both consumer preference for natural colors and the stability issues that affect all colorants.
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 use of botanically derived color stabilizers significantly extends the color stability of synthetic colors in beverages, maintaining color intensity for twice to five times longer than without stabilizers, even under UV exposure.
Implementation Method 1
prevents light-induced fading by including these compounds in the beverage
Implementation Method 2
It is believed that oxidation and/or reduction is primarily responsible for color instability or color fading
