Solution Overview

Problem

Existing edible emulsions lack microbiological and physical stability, and fail to provide a healthy fat profile and suitable organoleptic properties, making them unsuitable for substituting animal and vegetable fats in food products, especially baked goods.

Innovation Solution

An edible emulsion comprising thermogelling cellulose ethers, vegetable oils, a pH adjusting agent, and an anionic naturally occurring polysaccharide, with a pH range of 3.5 to 6.0 and low trans fatty acid content, is developed, along with a process that involves dispersing cellulose ethers in vegetable oils and dissolving the polysaccharide in water to create a stable emulsion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If vegetable oils are used to substitute animal and vegetable fats, then the trans fatty acid content is reduced and the fat profile becomes healthier, but the liquid consistency makes them unsuitable for industrial application in baked foods

Engineering Contradiction:
Improvetrans fatty acid contentVSAvoidsuitability for industrial application
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent changes the physical state parameter of vegetable oils from liquid to semi-solid by creating an emulsion system. The emulsion comprises vegetable oil (40-70 wt%), water (20-50 wt%), and stabilizing agents including cellulose derivatives (0.1-5 wt%) and proteins (1-10 wt%). This transformation allows the healthy vegetable oil to achieve the desired consistency for baked foods without hydrogenation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite emulsion system combining vegetable oil, water, cellulose derivatives, and proteins. This composite material achieves both the health benefits of vegetable oils and the functional properties of traditional fats. The specific combination includes emulsifiers (0.1-5 wt%), stabilizers (0.1-5 wt%), and thickening agents (0.1-5 wt%) to achieve the desired semi-solid consistency.

Inventive Principle:
Principle #40Composite materials

2Shape

If hydrogenated vegetable oils are used to give appropriate texture to food products, then the texture is improved, but unhealthy saturated fatty acids and trans fatty acids are formed

Engineering Contradiction:
ImprovetextureVSAvoidsaturated fatty acids and trans fatty acids
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful effect of hydrogenation into a beneficial alternative by using physical emulsification and stabilization methods instead of chemical hydrogenation. The emulsion system achieves the desired semi-solid texture through the synergistic action of cellulose derivatives, proteins, and emulsifiers, completely avoiding the formation of trans fatty acids and excessive saturated fats.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent replaces the chemical process of hydrogenation with a physical emulsification process. Instead of using hydrogen gas and catalysts to modify fatty acids, the patent uses mechanical mixing and stabilization with cellulose derivatives and proteins to achieve the desired texture, eliminating the formation of harmful trans fatty acids.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If fats are removed or substituted from food products, then the health profile is improved, but products have undesirable or unsuitable organoleptic features

Engineering Contradiction:
Improvefat content and compositionVSAvoidorganoleptic features
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent introduces cellulose derivatives and proteins as intermediary substances that mediate between the vegetable oil and water phases. These intermediaries (emulsifiers and stabilizers) allow the fat-free or low-fat product to achieve the desired organoleptic features by forming a stable emulsion structure that mimics the mouthfeel and texture of traditional fat-containing products.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Object-affected harmful factors

If existing edible emulsions are used to substitute fats, then the trans fatty acid content is reduced, but microbiological and physical stability during storage is insufficient

Engineering Contradiction:
Improvetrans fatty acid contentVSAvoidmicrobiological and physical stability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent creates a composite emulsion system combining multiple stabilizing agents: cellulose derivatives (0.1-5 wt%), proteins (1-10 wt%), emulsifiers (0.1-5 wt%), and stabilizers (0.1-5 wt%). This multi-component composite provides both microbiological stability (through pH control with acids 0.1-5 wt% and preservatives 0.1-2 wt%) and physical stability (through the synergistic action of different stabilizing agents), solving the stability problems of existing single-component emulsions.

Inventive Principle:
Principle #40Composite materials
