Solution Overview

Problem

Reducing sugar content in food products like breakfast cereals while maintaining their white, opaque appearance and consumer acceptance, as sugar contributes to both taste and appearance, and lowering sugar levels can negatively affect the expected frosted appearance due to decreased light diffraction from sugar crystals.

Innovation Solution

A method involving a reduced sugar frosting solution with sucrose, a foaming agent, and a stabilizing agent, whipped to create a foamed solution with specific overrun and density, then sprayed onto food products using a nozzle to maintain foam integrity and mimic traditional frosting appearance without adding artificial whiteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If sugar content is reduced in frosting, then health benefits improve, but appearance quality deteriorates

Engineering Contradiction:
Improvesugar contentVSAvoidappearance
Core Design Contradiction:
Quantity of substanceVSShape

Solution Approach 1:

The patent introduces a foaming agent as an intermediary substance that creates air bubbles in the frosting matrix. These air bubbles scatter light to produce the desired white, opaque appearance traditionally provided by sugar crystals, thereby compensating for reduced sugar content while maintaining health benefits

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the physical parameters of the frosting by controlling foam overrun (air incorporation) and bubble size distribution. By optimizing these parameters, the frosting achieves the necessary optical properties for appearance without relying on high sugar content, thus resolving the contradiction between reduced sugar and maintained appearance

Principle #35Parameter changes

2Productivity

If foam is sprayed through a nozzle, then application efficiency improves, but foam integrity deteriorates

Engineering Contradiction:
Improveapplication efficiencyVSAvoidfoam integrity
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by pre-forming the foam with optimal bubble size distribution and stability characteristics before spraying. The foaming agent and process parameters are optimized in advance to ensure the foam can withstand the mechanical stress of spraying while maintaining its structure and appearance properties

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent controls critical parameters including foam density, overrun, and bubble size to optimize both sprayability and foam integrity. By adjusting these parameters within specific ranges, the foam achieves sufficient stability for nozzle application while maintaining the desired appearance qualities

Inventive Principle:
Principle #35Parameter changes
