Solution Overview

Problem

Existing liquid creamers face challenges with physical and oxidative stability, leading to issues like phase separation, sedimentation, and rapid deterioration, especially in unhydrogenated oils, which are not shelf-stable and may develop off-flavors due to oxidation, making them unsuitable for long-term storage and use in beverages.

Innovation Solution

A creamer composition with a high proportion of oleic acid (at least 50%) and limited linoleic and linolenic acid, combined with hydrocolloids and emulsifiers, which improves physical and oxidative stability, allowing for a shelf-stable, homogeneous liquid creamer that remains stable at various temperatures without significant stabilizer use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If unhydrogenated domestic commodity oils (soybean, canola, sunflower oils) are used in liquid creamers, then the creamer avoids hydrogenated oils and trans-fatty acids, but the creamer develops rapid rancidity during storage

Engineering Contradiction:
Improveavoidance of hydrogenated oils and trans-fatty acidsVSAvoidoxidative stability during storage
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent changes the chemical composition parameters of the oil by specifying precise fatty acid ratios: at least 50% oleic acid, no more than 30% linoleic acid, and no more than 5% linolenic acid. This parameter optimization reduces oxidative susceptibility while maintaining liquid state, resolving the contradiction between avoiding hydrogenated oils and preventing rancidity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite oil composition by combining multiple oil sources with different fatty acid profiles to achieve the target composition. This composite approach allows leveraging the advantages of different oils while minimizing their individual weaknesses, particularly oxidative instability

Inventive Principle:
Principle #40Composite materials

2Ease of operation

If soft, liquid oils are used instead of hard fats, then plug formation is avoided at refrigerated temperatures, but oxidative instability increases

Engineering Contradiction:
Improveflowability and prevention of plug formationVSAvoidoxidative stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent optimizes the fatty acid composition parameters to achieve a balance between liquid state at refrigeration temperatures and oxidative stability. The high oleic acid content (≥50%) provides liquid consistency and flowability, while the limited polyunsaturated fat content (linoleic ≤30%, linolenic ≤5%) prevents rapid oxidation, resolving the contradiction between ease of operation and reliability

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If liquid creamers are formulated without sufficient stabilizers, then the formulation avoids excessive additives, but phase separation and creaming occur during storage

Engineering Contradiction:
Improveformulation simplicityVSAvoidphysical stability against phase separation
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The patent changes the oil composition parameters (high oleic acid, limited polyunsaturated fats) to inherently improve physical stability. This compositional optimization reduces the need for stabilizers by minimizing the tendency toward phase separation and creaming, resolving the contradiction between formulation simplicity and composition stability

Inventive Principle:
Principle #35Parameter changes
