Solution Overview

Problem

Conventional fat replacers fail to replicate the sensory characteristics of fat in food products, such as creaminess, appearance, palatability, texture, and lubricity, making them unsuitable as effective fat mimetics.

Innovation Solution

Microparticle compositions comprising a blend of dietary fibers, including hydrocolloids, viscous fibers, and prebiotic fibers, are formulated to mimic fat properties, with specific ratios and processing methods to achieve desired physiochemical properties like high viscosity, solubility, and emulsification stability, and are used to replace fat in food products.

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent uses a composite material system consisting of multiple dietary fiber types (hydrocolloids, viscous fibers, and prebiotic fibers) combined in specific ratios. This composite approach allows the fat replacer to simultaneously achieve fat-like sensory properties and health benefits, resolving the contradiction between fat reduction and sensory quality maintenance.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent optimizes specific parameters including particle size distribution (bimodal or multimodal distribution with specific diameter ranges), fiber ratio compositions, and physicochemical properties (viscosity, solubility, emulsification stability). By precisely controlling these parameters, the composition mimics fat's sensory characteristics while maintaining reduced fat content.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If dietary fiber compositions are formulated to mimic fat properties, then sensory characteristics are improved, but manufacturing complexity increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by pre-formulating optimized fiber blends with specific ratios and particle size distributions before final product manufacturing. The dietary fibers are pre-processed and characterized to ensure they meet target physicochemical properties, simplifying the overall manufacturing process while maintaining sensory quality.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates a simplified copy of fat's functional properties using dietary fiber compositions. Rather than attempting to replicate fat's complex chemical structure, the invention copies fat's sensory and textural characteristics through carefully designed fiber blends, achieving the desired effect with a more straightforward manufacturing approach.
