Solution Overview

Problem

Cereal processed food products, such as cooked rice and noodles, experience a decrease and deterioration of flavor and texture over time due to lipid oxidation and starch aging, especially when stored at room temperature or under a chilled state. Additionally, the use of edible oil and fat in these products leads to unpleasant flavors and odors.

Innovation Solution

The use of a seasoning liquid containing maltol and at least one aroma component selected from 5-Hydroxymethylfurfural, dimethyl sulfide, and 3-methylbutanal, added to cereal processed food products in a predetermined amount, helps to suppress the decrease and deterioration of flavor and texture. This seasoning liquid also mitigates the unpleasant flavors and odors associated with edible oil and fat.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cereal processed food products are stored at room temperature or under a chilled state for several hours, then storage and distribution convenience is improved, but lipid oxidation and starch aging progress, causing flavor and texture deterioration

Engineering Contradiction:
Improvestorage and distribution convenienceVSAvoidflavor and texture quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by adding specific aroma components (maltol, 5-hydroxymethylfurfural, dimethyl sulfide, and 3-methylbutanal) to the cereal processed food products before storage. These components are pre-introduced to counteract the lipid oxidation and starch aging that will occur during storage, thereby maintaining flavor and texture quality even when stored at room temperature or chilled states for several hours.

Inventive Principle:
Principle #10Preliminary action

2Shape

If edible oil and fat are added to cereal processed food products, then separation and texture are improved, but unpleasant flavors and odors are generated due to oxidation over time

Engineering Contradiction:
Improveseparation and textureVSAvoidunpleasant flavor and odor from oxidation
Core Design Contradiction:
ShapeVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful effect of oil oxidation into a beneficial outcome by introducing specific aroma components that counteract the unpleasant odors. The aroma components (maltol, 5-hydroxymethylfurfural, dimethyl sulfide, and 3-methylbutanal) are selected to mask or neutralize the oxidized oil odors, thereby allowing the use of edible oil and fat for texture improvement without generating unpleasant flavors.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent uses aroma components as intermediary substances that mediate between the edible oil and fat and the consumer's sensory perception. These intermediaries (specific aroma compounds) are introduced to modify the odor profile of the oxidized oil, transforming the harmful oxidation products into acceptable or even desirable flavor characteristics.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Temperature

If cereal processed food products are reheated after storage, then eating temperature is improved, but deteriorated odor and dry/crumbly texture become more conspicuous

Engineering Contradiction:
Improveeating temperatureVSAvoidflavor and texture quality
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-introducing aroma components that are stable through reheating processes. These components (maltol, 5-hydroxymethylfurfural, dimethyl sulfide, and 3-methylbutanal) are added before storage and remain effective after reheating, counteracting the deterioration that occurs during both storage and subsequent heating, thereby maintaining flavor and texture quality.

Inventive Principle:
Principle #10Preliminary action
