Solution Overview

Problem

Conventional fat-processed starches face issues with starch lumping during dispersion in water, difficulty in uniform dispersion, and reduced adhesion between ingredients and coatings, while soybean flour improves dispersibility but can act as an allergen and result in a protein-derived crunchy texture.

Innovation Solution

A fat-processed starch is developed by adding a fat composition with a specific iodine value of 125 to 170 and containing 35 ppm to 8,000 ppm of polyphenol to starch, which is then aged, providing excellent dispersibility and adhesion, and a soft, juicy texture when used as a coating material for fries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fat composition with iodine value of 125 to 170 and polyphenol content of 35 ppm to 8,000 ppm is added to starch and aged, then dispersibility and adhesion are improved, but the process complexity increases

Engineering Contradiction:
ImprovedispersibilityVSAvoidprocess complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent specifies precise parameter ranges for the fat composition (iodine value: 125-170, polyphenol content: 35-8,000 ppm) to achieve optimal dispersibility and adhesion. By controlling these chemical parameters, the invention transforms the starch-fat mixture into a product with improved workability without requiring complex processing equipment or procedures.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The aging process is performed as a preliminary action before the starch-fat mixture is used as a coating material. This preliminary treatment allows the fat to penetrate and bind to the starch grains in advance, ensuring excellent dispersibility and adhesion properties are already established before application, simplifying subsequent processing steps.

Inventive Principle:
Principle #10Preliminary action

2Strength

If conventional fat-processed starch is used, then adhesion is improved, but starch lumping occurs during dispersion

Engineering Contradiction:
ImproveadhesionVSAvoiddispersion uniformity
Core Design Contradiction:
StrengthVSStability of the object's composition

Solution Approach 1:

The patent identifies and controls specific parameters of the fat composition (iodine value between 125-170 and polyphenol content between 35-8,000 ppm) to simultaneously achieve strong adhesion and uniform dispersion. This parameter optimization prevents starch lumping while maintaining excellent adhesion, resolving the contradiction between these two properties.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention creates a composite material system where fat with specific chemical characteristics (unsaturated fatty acids indicated by iodine value and polyphenols) combines with starch. This composite structure ensures both strong binding (adhesion) and easy separation in water (dispersibility), preventing lumping while maintaining attachment strength.

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If soybean flour is added to improve dispersibility, then dispersibility is improved, but allergenic issues and crunchy texture are introduced

Engineering Contradiction:
ImprovedispersibilityVSAvoidallergenicity
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and utilizes only the necessary functional components (fat with specific iodine value and polyphenol content) to achieve dispersibility, eliminating the need to add soybean flour or other protein-containing materials. This extraction approach provides the desired dispersibility while avoiding the harmful allergic reactions and unwanted crunchy texture associated with soybean flour.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention uses a simple fat composition with defined chemical parameters as a short-living, easily degradable alternative to soybean flour. This fat-based solution provides temporary dispersibility enhancement during processing without leaving behind allergenic proteins or creating persistent crunchy textures, making it a safer and more desirable additive.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
