Solution Overview

Problem

Conventional soy protein-containing sheet-like food products lack both excellent texture and flexibility, particularly when used as food wrappers, and the addition of oil/fat to improve flexibility is disadvantageous from a caloric perspective.

Innovation Solution

A soy protein-containing sheet-like composition is produced by combining soy protein with a medium-chain triglyceride, specifically containing 90% by mass or more of fatty acids with 6 to 12 carbon atoms, such as caproic, caprylic, and lauric acids, in a ratio of 0.001 to 10 parts by mass relative to 100 parts of soy protein.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If oil/fat is added to soy protein-containing sheet-like food products to improve flexibility, then flexibility and texture are improved, but calorie content increases

Engineering Contradiction:
ImproveflexibilityVSAvoidcalorie content
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The invention extracts only the essential functional component (glycerol) from the triglyceride molecule, discarding the fatty acid portions that contribute to caloric content. This allows achieving flexibility improvement without the harmful caloric burden of complete oil/fat addition.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Glycerol acts as an intermediary substance that provides the plasticizing effect of oil/fat without the associated caloric penalty. It mediates between the need for flexibility and the desire to maintain low calorie content, delivering the beneficial mechanical property while avoiding the harmful metabolic impact.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Use of energy by moving object

If soy protein-containing sheet-like food products are made without oil/fat to maintain low calories, then calorie content is reduced, but flexibility deteriorates

Engineering Contradiction:
Improvecalorie contentVSAvoidflexibility
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The invention extracts only the essential functional component (glycerol) from the triglyceride molecule, discarding the fatty acid portions that contribute to caloric content. This allows achieving flexibility improvement without the harmful caloric burden of complete oil/fat addition.

AI summary

[Problem] To provide a soy protein-containing sheet-like composition having excellent texture and improved flexibility. [Solution] A soy protein-containing sheet-like composition containing soy protein and a medium-chain triglyceride. The medium-chain triglyceride preferably contains at least 90% by mass of fatty acid having 6 to 12 carbon atoms. The medium-chain fatty acid is preferably one or more selected from the group consisting of caproic acid, caprylic acid, capric acid, and lauric acid. The soy protein-containing sheet- like composition preferably contains 0.001 parts by mass to 10 parts by mass, inclusive, of the medium-chain triglyceride relative to 100 parts by mass of the soy protein.
