Solution Overview

Problem

Existing pancake and batter products are not microbiologically stable when refrigerated, leading to spoilage and loss of leavening action, and require additional processing steps like pasteurization or freezing to extend shelf life, which increase costs.

Innovation Solution

A ready-to-use packaged batter with a low water activity and low yield point, formulated with ingredients like flour, sugar, oil, and an oxidoreductase enzyme, that maintains stability and flowability for up to 12 weeks without the need for pasteurization or freezing, allowing multiple uses and maintaining cooking performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If batter is prepared from dry ingredients and stored in refrigerator, then convenience is improved, but microbial stability deteriorates and phase separation occurs

Engineering Contradiction:
ImproveconvenienceVSAvoidmicrobial stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies parameter changes by reducing water activity (Aw) to 0.93 or below through formulation adjustments. This critical parameter change prevents microbial growth while maintaining batter functionality and cooking performance, resolving the contradiction between convenience and microbial stability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite material strategies by combining specific ingredients including oxidoreductase enzymes, emulsifiers, and controlled ratios of fats and carbohydrates. This composite formulation creates a stable matrix that prevents both microbial growth and phase separation, enabling refrigerated storage without pasteurization

Inventive Principle:
Principle #40Composite materials

2Loss of time

If batter is prepared from dry ingredients, then preparation time is reduced, but batter stability deteriorates and leavening action is lost

Engineering Contradiction:
Improvepreparation timeVSAvoidbatter stability
Core Design Contradiction:
Loss of timeVSDuration of action of stationary object

Solution Approach 1:

The patent applies preliminary action by pre-formulating the batter with optimized ingredient ratios and adding oxidoreductase enzymes before packaging. This preliminary preparation ensures that leavening agents remain stable and functional during refrigerated storage, allowing the batter to maintain its leavening action weeks after preparation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the water activity parameter to 0.93 or below, which slows down chemical reactions and enzymatic activity that would otherwise degrade the batter. This parameter control preserves leavening action and prevents phase separation during extended refrigerated storage

Inventive Principle:
Principle #35Parameter changes

3Reliability

If pasteurization or freezing is applied to extend shelf life, then microbial stability is improved, but processing complexity and cost increase

Engineering Contradiction:
Improvemicrobial stabilityVSAvoidprocessing steps
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a simple, low-cost approach by using formulation-based preservation rather than expensive thermal or freezing processing. The oxidoreductase enzyme system and controlled water activity provide microbial stability without requiring complex pasteurization equipment or freezing infrastructure

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent achieves microbial stability through parameter changes in formulation (water activity reduction to 0.93 or below) rather than through thermal or mechanical processing. This eliminates the need for pasteurization or freezing steps, reducing processing complexity and cost while maintaining reliability

Inventive Principle:
Principle #35Parameter changes

4Reliability

If water activity is reduced to improve microbial stability, then refrigerated storage is extended, but yield point increases and flowability deteriorates

Engineering Contradiction:
Improvemicrobial stabilityVSAvoidflowability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent uses composite material strategies by incorporating emulsifiers and specific fat types that maintain low yield point even at reduced water activity. This composite formulation ensures the batter remains pourable and flowable while achieving the target water activity of 0.93 or below for microbial stability

Inventive Principle:
Principle #40Composite materials
