Umami Flavor Enhancement via MSG and GABA Synergy

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for enhancing umami flavor in food products rely heavily on monosodium glutamate (MSG), which is not universally accepted, and there is a need to achieve umami taste with reduced MSG proportions.

Innovation Solution

The method involves combining reduced proportions of MSG with γ-amino butyric acid (GABA) to enhance umami flavor, with GABA being added in compensatory proportions, typically within the range of 0.8-1.2 moles per mole of MSG, to achieve the desired umami effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If monosodium glutamate (MSG) is used to provide umami flavour, then umami taste is achieved, but the proportion of MSG required is high and not universally accepted

Engineering Contradiction:

Improveproportion of MSGVSAvoidunpopularity of MSG

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent combines MSG with GABA (γ-aminobutyric acid) to create a synergistic effect where the combination enhances umami flavor more effectively than MSG alone, allowing for reduced MSG proportions. The specific combination of 0.8-1.2 moles of GABA per mole of MSG creates a complementary relationship that resolves the contradiction by maintaining umami quality while reducing reliance on MSG.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention uses a composite flavoring system comprising both MSG and GABA in specific proportions rather than relying on a single substance. This composite approach leverages the umami properties of MSG while incorporating GABA's taste-improving characteristics, resulting in a more acceptable and effective flavor enhancement system that reduces the need for high MSG concentrations.

Inventive Principle:

Principle #40Composite materials

2Quantity of substance

If high proportions of MSG are used to achieve desired umami flavour, then umami intensity is sufficient, but the amount of MSG required is reduced when GABA is added

Engineering Contradiction:

Improveamount of MSGVSAvoidumami flavour quality

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent changes the compositional parameters by introducing GABA at specific molar ratios (0.8-1.2 moles per mole of MSG) to alter the flavor enhancement mechanism. This parameter change allows the system to achieve the same or better umami quality with significantly reduced MSG amounts, as GABA modifies the overall flavor profile and enhances the effectiveness of the remaining MSG.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

GABA acts as an intermediary substance that mediates between the umami flavor requirement and the desire to reduce MSG. It provides a bridging effect where GABA's taste-improving properties complement MSG's umami characteristics, allowing the system to maintain reliable umami quality while using less MSG than would be required without GABA.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method of providing umami taste to a consumable composition, comprising the addition to the composition of monosodium glutamate, in which the proportion of monosodium glutamate that would normally be used is reduced and replaced with a compensatory proportion of γ-amino butyric acid. A substantial reduction in MSG content is made possible.
