Solution Overview

Problem

Conventional bread crumb coatings often contain gluten, making them unsuitable for individuals with gluten-related disorders, and pulse-based alternatives can have an unappealing flavor and texture.

Innovation Solution

A method involving the separation, hydration, agglomeration, and heat treatment of pulse flours to produce gluten-free, low-protein pulse-based bread crumbs with improved taste and sensory properties, using processes like dehulling, fine milling, classification, and heat and moisture treatment to reduce protein and starch separation, and milling into various particle sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional wheat flour is used to produce bread crumb coatings, then the product has good taste and texture, but it contains gluten making it unsuitable for individuals with gluten-related disorders

Engineering Contradiction:
Improvesuitability for gluten-sensitive consumersVSAvoidunappealing flavor and texture of pulse-based alternatives
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies parameter changes by modifying the protein content parameter of pulse flour through classification to create low-protein fractions (10-20% protein), and by changing the physical state parameters through heat and moisture treatment (95-150°C at 18-55% moisture) to improve texture and flavor. These parameter transformations enable pulse-based products to match the sensory properties of wheat-based products while maintaining gluten-free status.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If pulse flour is used directly to create gluten-free bread crumbs, then the product is suitable for gluten-sensitive consumers, but it has unappealing flavor and texture

Engineering Contradiction:
Improvegluten-free suitabilityVSAvoidunappealing flavor and texture
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies preliminary action through pre-treatment steps including classification to separate low-protein fractions, hydration to 18-55% moisture content, and heat treatment at 95-150°C before final drying. These preliminary transformations modify the pulse flour properties in advance, eliminating unappealing flavors and improving texture, so that the final product closely resembles traditional wheat-based bread crumbs in sensory quality.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If pulse flour undergoes classification to reduce protein content, then the product becomes more suitable for gluten-free applications, but the processing complexity increases

Engineering Contradiction:
Improvegluten-free certification suitabilityVSAvoidprocessing steps including classification and heat treatment
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing pulse flour into different protein fractions through classification, separating low-protein (10-20%) from medium-protein (20-36%) fractions. This segmentation enables selective use of the low-protein fraction for gluten-free applications where wheat-like texture is desired, while the process remains systematic and manageable through standardized classification equipment.

Inventive Principle:
Principle #1Segmentation

AI summary

Pulse-based bread crumbs, coatings, and pre-dust products having an improved taste, texture and end use properties. The bread crumb, coating, and pre-dust products are produced by heat and moisture treatment at 100% by dry weight with pulse flours, e.g. pea flour, lentil flour, chickpea flour, faba bean flour, navy bean flour, pinto bean flour, black eye bean flour and black bean flour.
