Lutein Micellar Formulation for Egg Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to increase the bioavailability and deposition of carotenoids, particularly lutein, in egg yolks to enhance their nutritional value and health benefits, as current levels are low and declining in human consumption.
Innovation Solution
A formulation combining carotenoids with vegetable oil, a surfactant, a chelating agent, an antioxidant, and an alkali is used to improve absorption and deposition in poultry, involving saponification and emulsification processes to enhance micelle formation and protect carotenoids from oxidation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If carotenoids are added to poultry diets in traditional forms, then some deposition occurs in egg yolks, but the deposition level remains very low (approximately 0.1 mg/100 g)
Solution Approach 1:
The patent transforms carotenoids from their native crystalline form into a micellarized formulation through chemical modification (saponification of carotenoid esters) and physical encapsulation in micelles formed by vegetable oil and surfactant. This parameter change in molecular state and physical form dramatically improves bioavailability and deposition efficiency in egg yolks
Solution Approach 2:
The patent introduces micelles as an intermediary vehicle to transport carotenoids through the digestive system. The micellar structure, formed by the combination of vegetable oil and surfactant, acts as a mediator that enhances the solubility and absorption of fat-soluble carotenoids in the aqueous environment of the intestine, thereby improving their deposition in egg yolks
2Reliability
If carotenoids are exposed to oxidation environments, then they degrade and lose effectiveness, but protection mechanisms are needed to maintain stability
Solution Approach 1:
The patent converts the harmful oxidative environment into a beneficial protective mechanism by incorporating antioxidants into the formulation. These antioxidants scavenge free radicals and prevent oxidation of carotenoids, transforming the potentially harmful oxidative conditions into an opportunity for enhanced carotenoid stability and bioavailability through the synergistic formulation
3Productivity
If simple carotenoid supplements are used, then the formulation is simple and cheap, but the absorption and deposition efficiency is insufficient
Solution Approach 1:
The patent creates a composite formulation by combining carotenoids with vegetable oil, surfactant, and antioxidants. This composite material integrates multiple functional components that work synergistically: the vegetable oil and surfactant form micelles for enhanced solubility and absorption, while antioxidants provide protection against degradation, collectively achieving superior deposition efficiency
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 new formulation significantly increases lutein levels in chicken blood plasma and egg yolks, achieving up to 1.21 mg/100 g edible portion, a 54% increase over traditional methods, with consistent deposition and enhanced antioxidant power.
Implementation Method 1
The presence of dietary fat is thought to be important for micelle formation in the small intestine; dietary fat therefore, may also be crucial for absorption of carotenoids. The formulations consist of a bioavailable source of carotenoids combined with a vegetable oil, a surfactant
Implementation Method 2
The formulations are made by saponifying the plant extracts containing carotenoid ester
Implementation Method 3
an antioxidant, an alkali and a solvent to improve the amount of carotenoids deposited in the yolk

AI summary
The absorption and deposition of carotenoids added to poultry diets into the yolk of eggs produced by the poultry is improved by adding a carotenoid formulation comprising a carotenoid, a vegetable oil, a surfactant, a chelating agent, an antioxidant, an alkali and a solvent. The carotenoid formulation can reduce the crystalline nature of lutein for its better dissolution in the formulation and the diet. This new formulation is capable of making more micelles for an effective transfer of lutein from the formulations to the aqueous layer. The new formulation can increase the bioavailability of lutein in chicken biological system and leads to more deposition in the blood and the egg. The lutein deposition in the egg was consistent for an extended period of time when this new formulation was added to the diet. Addition of this carotenoid formulation to the diet increased the antioxidant power of the blood. Eggs produced by poultry fed diets supplemented by the formulation have in excess of 0.80 mg carotenoids per 100 grams of edible portion and thus serve as an important source of carotenoids in the human diet.
