Solution Overview

Problem

Existing human milk fat substitutes for infant formulas are expensive to produce due to high costs associated with achieving a fatty acid profile similar to human milk fat, which is essential for efficient nutrient absorption but difficult to replicate at a lower cost.

Innovation Solution

Development of a novel enzymatically prepared fat base composition with a specific fatty acid distribution, including at least 60% of saturated fatty acids at the sn-2 position being palmitic acid, and blending with vegetable oils to achieve a cost-effective human milk fat substitute with improved calcium and fatty acid absorption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional vegetable oils are used to produce human milk fat substitutes, then production costs are reduced, but the fatty acid profile and absorption efficiency do not match human milk fat

Engineering Contradiction:
Improveproduction costVSAvoidfatty acid profile accuracy
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by modifying the fatty acid composition parameters of the fat substitute to closely match human milk fat. Specifically, it achieves 70-85% of the desired sn-2 palmitic acid position and 40-60% sn-2 saturated fatty acid ratio, transforming the fatty acid profile from conventional vegetable oil to a human milk-like composition that improves absorption while maintaining cost-effectiveness

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite fat substitute composition by combining multiple vegetable oils (soybean, corn, sunflower, canola) in specific ratios with controlled fatty acid profiles. This composite approach allows the formulation to achieve a balanced fatty acid distribution similar to human milk while utilizing cost-effective vegetable oil sources

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If palmitic acid is esterified at sn-1 and sn-3 positions in vegetable oils, then the fat can be produced at lower cost, but nutrient absorption efficiency is reduced

Engineering Contradiction:
Improveproduction costVSAvoidnutrient absorption efficiency
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent applies local quality by specifically positioning palmitic acid at the sn-2 position of triglycerides, creating a localized fatty acid distribution pattern that differs from conventional vegetable oils. This specific positioning at the sn-2 position (where 70-85% of palmitic acid should be located) is known to enhance absorption efficiency while maintaining cost-effective production

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the positional parameter of palmitic acid esterification from the conventional sn-1 and sn-3 positions to the sn-2 position, transforming the triglyceride structure to improve absorption. This parameter change achieves 70-85% sn-2 palmitic acid positioning, which significantly enhances nutrient absorption efficiency

Inventive Principle:
Principle #35Parameter changes

3Reliability

If a fatty acid profile similar to human milk fat is achieved, then absorption efficiency is improved, but production costs increase

Engineering Contradiction:
Improveabsorption efficiencyVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies partial action by achieving a close approximation of the human milk fat profile without requiring perfect replication. It achieves 70-85% sn-2 palmitic acid positioning and 40-60% sn-2 saturated fatty acid ratio, which provides sufficient absorption benefits while avoiding the extreme costs of perfectly replicating human milk fat composition

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent uses composite materials by blending multiple vegetable oils with complementary fatty acid profiles to create a cost-effective substitute. This composite approach combines soybean, corn, sunflower, and canola oils in optimized ratios to achieve the desired fatty acid distribution at lower production cost than single-source alternatives

Inventive Principle:
Principle #40Composite materials
