Tocopheryl Acetate Stabilizes 8'-Apo-Beta-Carotene-8'-Al Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverages containing 8'-Apo-β-caroten-8'-al (apoal) face challenges in maintaining color stability due to the lack of effective antioxidants, as tocopheryl acetate, previously not recognized as an antioxidant, is found to enhance color stability when added to apoal-based beverages.
Innovation Solution
Embedding apoal and tocopheryl acetate in a matrix of protective colloids or emulsifiers, either together or separately, and adding tocopheryl acetate to apoal-based beverages to stabilize the color, using modified food starches and emulsifiers like OSA-starch and polysorbates, and incorporating antioxidants like tocopherols and ascorbic acid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If tocopheryl acetate is added to apoal-based beverages, then color stability is improved, but antioxidant activity is not enhanced (since tocopheryl acetate lacks significant antioxidant activity)
Solution Approach 1:
The patent changes the chemical form of vitamin E from tocopherol to tocopheryl acetate, which alters the molecular structure and properties. This parameter change enables the additive to provide color stability without relying on antioxidant activity, as the acetate ester form does not exhibit significant antioxidant properties in vitro
Solution Approach 2:
Instead of using antioxidants to prevent color degradation, the patent inverts the approach by using a non-antioxidant compound (tocopheryl acetate) that stabilizes color through a different mechanism, likely involving interaction with the apoal or protective colloid matrix rather than scavenging free radicals
2Stability of the object's composition
If apoal is embedded in a matrix of protective colloid, then color stability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent uses composite material systems where apoal is embedded in a protective colloid matrix, creating a stabilized formulation. The protective colloid provides a matrix that protects the apoal from degradation while maintaining color stability, and tocopheryl acetate is integrated into this composite system to further enhance color stability
Solution Approach 2:
The formulation employs a nested structure where apoal is embedded within the protective colloid matrix, and tocopheryl acetate is incorporated into this existing structure. This nested arrangement allows multiple functional components to work together within a unified formulation system
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 addition of tocopheryl acetate significantly improves the color stability of apoal-based beverages, measured by reduced color change (ΔE* ≤ 10) over storage time, even under light exposure, resulting in clear and visually stable drinks.
Implementation Method 1
tocopheryl acetate - in contrast to tocopherol - has not been known as antioxidant so far... the addition of tocopheryl acetate to a beverage comprising apoal leads to improved color stability
Implementation Method 2
apoal embedded in a matrix of protective colloid... tocopheryl acetate embedded in a matrix of protective colloid
