Solution Overview

Problem

High cereal and wholegrain content in cereal-based powders poses challenges for reconstitution in liquids due to poor texture and viscosity, making it difficult to achieve a smooth and instant beverage product.

Innovation Solution

Cereal-based flakes with at least 26% dry weight of wholegrain cereal, produced by mixing cereal flour with water, subjecting it to enzymatic hydrolysis, heat treatment, and roller-drying, which allows for easy dispersion in cold liquids, providing a smooth instant drink with at least 10g of cereal per 100mL.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If cereal-based powders with high cereal and wholegrain content are used, then nutritional value is improved, but texture and viscosity deteriorate making reconstitution difficult

Engineering Contradiction:
Improvecereal contentVSAvoidreconstitution ease
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent applies parameter changes by controlling the gelatinisation temperature and degree during processing. The cereal-based powder is treated at temperatures below the gelatinisation point of wholegrain starch, maintaining a specific gelatinisation degree that enables easy reconstitution while preserving high cereal content (at least 10g per 100mL). This temperature parameter control resolves the contradiction between high cereal content and reconstitution ease.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite material system combining cereal flour, water, and specific additives (such as maltodextrin or modified starch) in controlled proportions. This composite structure allows the powder to maintain high cereal content while the combination of components provides optimal dispersibility and smooth texture upon reconstitution, resolving the contradiction between nutritional density and operational ease.

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If high wholegrain cereal content is used, then fibre and vitamin content is improved, but texture quality deteriorates

Engineering Contradiction:
Improvewholegrain cereal contentVSAvoidtexture quality
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent controls the gelatinisation degree as a critical parameter to maintain texture quality. By processing at temperatures below wholegrain starch gelatinisation (e.g., 60-80°C) and controlling moisture content, the patent achieves smooth texture despite high wholegrain content (at least 30% of total cereal content). This parameter control resolves the contradiction between wholegrain quantity and texture quality.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies local quality by creating different structural characteristics in different parts of the product matrix. The cereal particles maintain their integrity and wholegrain structure locally, while the surrounding matrix (modified starch, maltodextrin) provides smooth texture and easy dispersibility. This local differentiation allows high wholegrain content without compromising overall texture quality.

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If cereal flour is mixed with water and processed traditionally, then cereal content is maintained, but dispersion in cold liquid becomes difficult

Engineering Contradiction:
Improvecereal contentVSAvoiddispersion stability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent changes the physical-chemical parameters of the cereal-based powder through controlled gelatinisation at sub-gelatinisation temperatures and specific moisture content control (15-25%). These parameter changes create a powder structure with enhanced wettability and dispersibility that allows stable dispersion in cold liquids while maintaining high cereal content. The modified starch or maltodextrin addition further modifies these parameters for optimal cold liquid dispersion.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces intermediary substances such as modified starch, maltodextrin, or hydrocolloids that act as mediators between the cereal particles and cold liquid. These intermediaries improve wettability and prevent clumping, enabling stable dispersion of high cereal content powders in cold liquids without requiring heating or extensive stirring.

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The flakes ensure a smooth, creamy, and highly nutritious instant cereal drink with high wholegrain content can be easily prepared in cold liquids without heating, maintaining a regular texture and high fiber content.

Implementation Method 1

Enzymatic hydrolysis can be used in the preparation of cereal-containing products in order to facilitate processing. This method is also used to liquefy cereal-containing products and, in infant food applications, to 'pre-digest' the starch, thus making it more readily available once ingested.

Methodology Applied
Scientific EffectEnzymatic hydrolysis: Hydrolysis

Implementation Method 2

The cereal-based flakes may be obtained by roller-drying
