Solution Overview

Problem

Sponge cakes made with fructooligosaccharides tend to become concave in the center during baking, which is undesirable, and existing technologies do not effectively prevent this issue while maintaining the physiological benefits of fructooligosaccharides.

Innovation Solution

Incorporating a water-soluble polymer such as collagen peptide, xanthan gum, or guar gum into the sponge cake dough, specifically using 1-kestose as the fructooligosaccharide, to prevent center concavity and maintain the physiological benefits of fructooligosaccharides.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fructooligosaccharide is used as a saccharide ingredient in sponge cake, then physiological functions (decay resistance, bifidobacterium promotion, lipid metabolism improvement, immunity regulation, blood sugar control) are improved, but the sponge cake becomes concave in the center after baking

Engineering Contradiction:
Improvephysiological functionVSAvoidcenter concavity
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

A water-soluble polymer is introduced as an intermediary substance to mediate between the fructooligosaccharide and the dough matrix. The polymer interacts with both the fructooligosaccharide and the dough components, preventing the harmful concavity effect while preserving the beneficial physiological functions of the fructooligosaccharide.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention creates a composite material system combining fructooligosaccharide with a water-soluble polymer. This composite approach allows the fructooligosaccharide to maintain its physiological benefits while the polymer component prevents the unwanted center concavity during baking, achieving both improved reliability and acceptable shape.

Inventive Principle:
Principle #40Composite materials

2Reliability

If fructooligosaccharide is used to substitute sugar in sponge cake, then health benefits are improved, but manufacturing precision (uniform thickness) deteriorates due to center shrinkage

Engineering Contradiction:
Improvehealth benefitVSAvoidthickness uniformity
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The water-soluble polymer serves as a mediator that intervenes in the interaction between fructooligosaccharide and dough during baking. It prevents the shrinkage that would otherwise occur in the center, thereby maintaining uniform thickness while allowing the health benefits of fructooligosaccharide to be realized.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention changes the physical and chemical parameters of the dough system by adding a water-soluble polymer. This modification alters the baking behavior of the dough containing fructooligosaccharide, preventing center shrinkage and achieving uniform thickness while preserving the health benefits.

Inventive Principle:
Principle #35Parameter changes

3Shape

If water-soluble polymer is added to sponge cake dough containing fructooligosaccharide, then center concavity is prevented, but device complexity (ingredient composition) increases

Engineering Contradiction:
Improvethickness uniformityVSAvoidingredient composition
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The addition of a water-soluble polymer changes key parameters of the dough system, specifically its rheological properties and water binding capacity. These parameter changes enable the dough to maintain uniform thickness during baking without requiring complex processing equipment or multiple ingredients, simply by adjusting the compositional parameters.

Inventive Principle:
Principle #35Parameter changes
