Umami Flavor Composition from Vegetable Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for delivering umami flavor in the food industry often rely on monosodium glutamate (MSG), which has negative consumer perception, and fail to effectively utilize vegetable processing side streams as natural flavor sources due to MSG concentration during processing, leading to environmental issues and unacceptably high MSG levels in flavor compositions.
Innovation Solution
A process using membrane technologies such as ultrafiltration and reverse osmosis to concentrate umami flavor compounds from vegetable cooking or blanching waters, specifically from peas, corn, and other vegetables, resulting in a flavor composition with less than 1% MSG content, avoiding the concentration of natural MSG and providing a sustainable, consumer-friendly umami flavor solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If membrane filtration or concentration technologies are used to process vegetable side streams, then umami flavor compounds can be recovered and utilized, but MSG content becomes concentrated to unacceptably high levels
Solution Approach 1:
The patent divides the concentration process into multiple stages with different membrane types (microfiltration, ultrafiltration, nanofiltration, reverse osmosis) that selectively separate different molecular sizes and types of compounds. This segmentation allows recovery of umami flavor compounds while controlling MSG concentration at acceptable levels.
Solution Approach 2:
Different regions of the processing system use different membrane technologies with specific pore sizes and selectivities tailored to their function. For example, ultrafiltration membranes with specific molecular weight cut-offs are used to retain larger flavor compounds while allowing smaller molecules to pass, creating local quality differences in the separation process.
2Quantity of substance
If conventional concentration methods (evaporation, reduction) are used on vegetable cooking water, then water can be removed and flavor compounds concentrated, but environmental problems arise due to high chemical oxygen demand
Solution Approach 1:
The patent replaces thermal concentration methods (evaporation, reduction) with membrane filtration technologies that use mechanical pressure-driven separation instead of heat. This substitution achieves flavor compound concentration without the high energy input and chemical oxygen demand associated with thermal processing.
Solution Approach 2:
The patent changes the fundamental parameter of concentration from thermal (heat-based evaporation) to mechanical (pressure-driven membrane filtration). This parameter change allows concentration of flavor compounds while avoiding the harmful environmental effects of high chemical oxygen demand generated by thermal processing.
3Reliability
If MSG is used as a umami flavor provider, then strong umami taste is achieved, but consumer perception becomes negative in many countries
Solution Approach 1:
The patent extracts and concentrates natural umami flavor compounds from vegetable side streams using membrane filtration, creating a natural flavor source that does not rely on added MSG. This extraction approach provides umami taste while avoiding negative consumer perception associated with MSG additives.
Solution Approach 2:
The patent utilizes the vegetable processing side streams themselves as the source of umami flavor, allowing the system to be self-sufficient. The cooking water that would normally be discarded is recovered and concentrated to provide natural umami flavor, eliminating the need for external MSG additives and improving consumer acceptance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The process effectively produces a natural umami flavor composition without added MSG, reducing environmental impact by recycling water and offering a consumer-friendly labeling option, while maintaining a strong umami taste in culinary products.
Implementation Method 1
concentrate the cooking water by subjecting it to one or more membrane filtration operations, in particular an ultrafiltration operation
Implementation Method 2
subjecting it to one or more membrane filtration operations, in particular an ultrafiltration operation followed by a reverse osmosis filtration

AI summary
A process for preparing a flavour composition having an umami flavour/taste and a MSG content of less than 1 wt% (% weight by total dry matter) comprising the steps of: a) heating vegetable matter in water at any given temperature to give cooking water containing flavour-active compounds extracted from the vegetable matter; b) separating the vegetable matter from the cooking water; and c) concentrating the cooking water to provide the flavour composition. Claims are also directed to the composition obtainable from the process and to food products such as soups and snacks including the composition.
