Infant Milk Formula Fat Gradient via Bimodal Droplet Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant milk formulas do not mimic the natural fat concentration gradient present in breast milk, where fat concentration increases during feeding, which is essential for mimicking the natural feeding process.
Innovation Solution
A method involving a liquid composition with larger fat droplets, specifically 5-25 micrometers in diameter, creating a fat gradient when the formula is fed, allowing for a concentration difference similar to breast milk, achieved through low-intensity homogenization and specific processing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional infant milk formula is used with small fat droplets, then the formula remains homogeneous and stable, but it does not mimic the natural fat concentration gradient of breast milk
Solution Approach 1:
The patent applies local quality by creating different fat droplet sizes within the same formula - larger droplets (5-25 μm) that cream to the top to mimic hind-milk, and smaller droplets that remain suspended to mimic fore-milk. This spatial differentiation of droplet characteristics within the homogeneous formula enables the fat gradient effect while maintaining overall formula stability.
2Adaptability or versatility
If larger fat droplets (5-25 micrometers) are used in the formula, then a fat gradient is formed mimicking breast milk, but the formula may become less homogeneous
Solution Approach 1:
The patent segments the fat phase into two distinct droplet size populations: larger droplets (5-25 μm) that will cream to create the fat gradient, and smaller droplets that maintain suspension and homogeneity. This segmentation of the fat component allows both the gradient formation and homogeneous appearance to coexist in the formula.
3Ease of manufacture
If the formula is made homogeneous with small fat droplets, then it is easier to manufacture and store, but it does not provide the fat concentration differences occurring during breast feeding
Solution Approach 1:
The patent applies parameter changes by controlling the fat droplet size distribution during manufacturing - specifically creating a bimodal distribution with droplets in the 5-25 μm range. This parameter control during production enables the formula to naturally form a fat gradient through creaming while maintaining manufacturing feasibility using standard homogenization equipment.

Function Achieved in This Case
This method effectively mimics the natural fat intake kinetics of breastfed infants, potentially influencing gastric emptying, digestion, and absorption, thereby improving dietary fat utilization and infant development.
Implementation Method 1
when using a formula comprising larger fat droplet than those found in conventional infant formula, a fat gradient is formed within the liquid
Implementation Method 2
