Sensory Modifiers Reduce Bitterness in Plant-Based Meat Substitutes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plant-based meat substitutes often have undesirable sensory attributes such as bitterness, unpleasant mouthfeel, and aftertaste, which limit consumer preference and application.
Innovation Solution
Incorporating a sensory modifier comprising at least 2.0% plant-based protein and between 0.001% and 1.0% dicaffeoylquinic acid or its salts, along with other caffeoyl-substituted quinic acids, to reduce plant protein flavor intensity and improve mouthfeel when cooked to an internal temperature of 73.9°C.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plant-based proteins are used in meat substitute compositions, then the product provides a meat-like texture and nutritional benefits, but the composition develops undesirable sensory attributes including bitterness, unpleasant mouthfeel, and aftertaste
Solution Approach 1:
The patent introduces sensory modifiers (dicaffeoylquinic acid and related compounds) as intermediary substances that mediate between the plant-based protein and the consumer's sensory perception. These modifiers specifically target and reduce the bitter and unpleasant sensory attributes while preserving the desired meat-like texture, effectively acting as a bridge that filters out harmful sensory characteristics.
Solution Approach 2:
The patent applies parameter changes by modifying the sensory profile of the composition through controlled addition of sensory modifiers at specific concentrations (0.001% to 1.0% wt). This changes the sensory parameters (bitterness, mouthfeel, aftertaste) without altering the fundamental protein structure or nutritional composition, thereby maintaining texture while improving sensory acceptability.
2Object-affected harmful factors
If sensory modifiers are added to reduce plant protein flavor intensity, then the palatability of meat substitutes improves, but the composition complexity increases
Solution Approach 1:
The sensory modifier composition serves multiple functions simultaneously: it reduces bitterness, improves mouthfeel, eliminates aftertaste, and maintains meat-like texture. This multi-functionality reduces the need for multiple separate additives, thereby managing composition complexity while achieving comprehensive sensory improvement.
Solution Approach 2:
The patent uses a composite sensory modifier system comprising dicaffeoylquinic acid in combination with other related compounds (monocaffeoylquinic acids, monoferuloylquinic acids, etc.). This composite approach creates a synergistic effect that achieves superior sensory modification compared to single compounds, while the defined concentration ranges keep the overall composition manageable.

AI summary
A meat substitute composition having a plant-based protein and a sensory modifier, such that the composition has reduced bitterness and/or plant protein flavor relative to an equivalent meat substitute composition without the sensory modifier. The sensory modifier may include a dicaffeoylquinic acid or salt thereof; and one or more compounds selected from the group consisting of monocaffeoylquinic acids, monoferuloylquinic acids, diferuloylquinic acids, monocoumaroylquinic acids, dicoumaroylquinic acids, and salts thereof.
