Solution Overview

Problem

Challenges in producing snack products with high legume content include low dough cohesiveness, high stickiness, and poor sheetability, leading to issues such as dry mouthfeel, chalky after-taste, and gritty texture.

Innovation Solution

Incorporating low oxidation transglutaminase into legume dough at specific concentrations and temperatures to crosslink proteins, reducing stickiness, and enhancing sheetability, resulting in machinable and sheetable dough for products like tortilla-style chips.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If high levels of legumes (60-100 wt.%) are incorporated into dough to enhance nutritional value, then nutrition value and consumer health perception are improved, but dough cohesiveness decreases and stickiness increases

Engineering Contradiction:
Improvenutrition valueVSAvoiddough cohesiveness
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent introduces corn starch as an intermediary component to mediate between legume flour and water in the dough system. This intermediary helps bridge the gap caused by high legume content, providing structural support and reducing stickiness while maintaining the high nutritional value from legumes.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent modifies the dough composition parameters by adding specific amounts of corn starch (5-20 wt.% of total dough weight) and controlling water content (60-80 wt.% of total dough weight). These parameter changes adjust the rheological properties of the dough, improving cohesiveness and reducing stickiness while preserving high legume content for nutritional benefits.

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If high levels of legumes are incorporated into dough, then nutrition value is improved, but sheetability deteriorates

Engineering Contradiction:
Improvenutrition valueVSAvoidsheetability
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

Corn starch serves as a mediating component that facilitates sheeting operations in high-legume doughs. The starch granules provide a lubricating effect and adjust the dough's plasticity, enabling it to be rolled and shaped into thin sheets without excessive stickiness or cracking, thus improving manufacturability while maintaining high nutritional content.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

By adjusting the ratio of corn starch to legume flour and controlling water content within specific ranges, the patent optimizes the dough's rheological parameters for sheeting. This allows the dough to achieve the right balance of softness and elasticity needed for easy sheeting while preserving 60-100 wt.% legume content for nutritional value.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If high levels of legumes are used in snack products, then nutrition value is enhanced, but texture quality deteriorates with dry mouthfeel, chalky after-taste, and gritty texture

Engineering Contradiction:
Improvenutrition valueVSAvoidtexture quality
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent modifies the texture profile by adjusting the water content (60-80 wt.% of total dough weight) and adding corn starch in specific proportions. These parameter changes create a more balanced moisture distribution and softer matrix structure in the final snack product, reducing the dry mouthfeel, chalky after-taste, and gritty texture associated with high-legume products while maintaining their nutritional benefits.

Inventive Principle:
Principle #35Parameter changes

AI summary

A snack product includes legume, deactivated transglutaminase (TG) oil, moisture, and/or seasonings. The legume dough used to make the snack product is modified to include transglutaminase (TG) to increase its sheetability. The legume dough may include from about 60 wt. % to about 100 wt. % legumes. An exemplary method of making the modified legume dough includes adding about 0.5 wt. % to about 5 wt. % TG, incubating the modified legume dough at about 100° F. to about 130° F. for between about 5 minutes to about 120 minutes.
