Solution Overview

Problem

Low-oil and low-fat snack foods often have an inferior mouthfeel due to the lack of lubrication, which is not adequately addressed by existing additives like xanthan gum and alginate gum, resulting in a dry sensation compared to full-fat products.

Innovation Solution

The use of lecithins or low hydrophilic-lipophilic balance (HLB) value emulsifiers to tailor the wetting and lubrication properties of edible fats in low-oil food products, enhancing their mouthfeel and tactile perception by allowing more rapid wetting of the bolus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If oil and fat content is reduced in food products, then health benefits are improved, but mouthfeel and lubrication properties deteriorate

Engineering Contradiction:
Improveoil and fat contentVSAvoidmouthfeel and lubrication
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent introduces free fatty acids as intermediary substances that mediate between the reduced oil/fat content and the desired mouthfeel. These free fatty acids are applied topically to the food product surface, acting as a bridge that provides lubrication without requiring high bulk oil content, thus resolving the contradiction between reduced fat and maintained mouthfeel

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies free fatty acids specifically to the surface of the food product rather than uniformly throughout the bulk. This localized application provides lubrication and mouthfeel enhancement at the consumer interface (surface) while maintaining low overall fat content in the product, resolving the contradiction between reduced bulk fat and surface-level mouthfeel

Inventive Principle:
Principle #3Local quality

2Quantity of substance

If free oil is removed from low-oil food products, then health benefits are improved, but tactile perception and mouthfeel deteriorate

Engineering Contradiction:
Improvefree oil contentVSAvoidtactile perception
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

Free fatty acids serve as intermediary substances that replicate the tactile properties of free oil without requiring the presence of bulk free oil. These intermediaries provide the necessary lubrication and tactile perception at the surface level while the product maintains low overall free oil content for health benefits

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If xanthan gum and alginate gum are added to low-fat products, then viscosity is improved, but mouthfeel still remains dry and unsatisfactory

Engineering Contradiction:
ImproveviscosityVSAvoidmouthfeel
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent introduces free fatty acids as a superior intermediary substance that directly addresses mouthfeel through lubrication. Unlike xanthan and alginate gums that only provide viscosity stabilization, free fatty acids provide both viscosity stability and direct lubrication at the surface, resolving the insufficient mouthfeel problem that gums alone cannot solve

Inventive Principle:
Principle #24Intermediary (Mediator)
