Encapsulated Caffeine Complexes Mask Bitterness in Energy Drinks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Energy drinks and foods with high caffeine content often have an unappealing bitter taste due to the inherent bitterness of caffeine, making them less appealing to consumers despite the addition of large amounts of sweeteners and flavors.
Innovation Solution
The use of encapsulated caffeine complexes, formed with a 1:1 molar ratio of caffeine and organic acids such as caffeic acid, malonic acid, or succinic acid, which are dispersed in a base composition like energy drinks or food products, maintaining a pH of 2 to 5 to prevent bitterness perception during consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If high caffeine content is added to energy drinks, then energy boost is improved, but bitter taste increases making the product unappealing
Solution Approach 1:
A flavor masking agent serves as an intermediary substance that interacts with the bitter taste of caffeine, blocking or reducing its perception. The masking agent is added to the energy drink formulation at specific concentrations (0.1-10% w/v) to counteract the bitter taste while preserving the energy-boosting effects of high caffeine content (50-500 mg per serving).
Solution Approach 2:
The patent changes the chemical and sensory parameters of the energy drink by introducing flavor masking agents that alter the taste profile. By adjusting the concentration of masking agents and their chemical structure (using compounds with specific functional groups), the bitter taste parameter is modified while maintaining the desired energy effects.
2Object-affected harmful factors
If large amounts of sweeteners and flavors are added to mask caffeine bitterness, then taste appeal is improved, but product complexity and ingredient count increase
Solution Approach 1:
The flavor masking agent performs multiple functions simultaneously: it masks the bitter taste of caffeine, provides desirable flavor notes, and contributes to the overall mouthfeel of the beverage. This multi-functionality reduces the need for separate bittering agents, flavor enhancers, and taste modifiers, thereby simplifying the ingredient list while improving taste appeal.
3Object-affected harmful factors
If encapsulated caffeine complexes are used, then bitter taste is reduced, but manufacturing process complexity increases
Solution Approach 1:
The caffeine is pre-complexed with flavor masking agents during the manufacturing process to form encapsulated complexes before the final product is assembled. This preliminary action of complexation occurs under controlled conditions (specific pH ranges, temperature, and mixing parameters) to ensure consistent formation of the complexes, which then can be easily incorporated into the energy drink formulation without requiring additional processing steps.
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 encapsulated caffeine releases caffeine in a controlled manner, providing a burst of energy without the bitter taste, enhancing consumer acceptance of high-caffeine products by masking the bitterness and maintaining flavor profiles.
Implementation Method 1
The encapsulated caffeine is a caffeine complex including caffeine and an organic acid in about a 1:1 molar ratio. The encapsulated caffeine releases about 50 mg to about 200 mg of caffeine when consumed.
Implementation Method 2
The encapsulated caffeine is a caffeine complex including caffeine and an organic acid in about a 1:1 molar ratio. Suitable organic acids are selected from the group consisting of caffeic acid, oxalic acid, malonic acid, maleic acid, succinic acid, glutaric acid, glutamic acid, adipic acid and combinations thereof.
Implementation Method 3
the base composition has a pH of about 2 to about 5. The encapsulated caffeine releases about 50 mg to about 200 mg of caffeine when consumed.
Data Source
AI summary
The method includes forming encapsulated caffeine from a caffeine complex that includes caffeine and an organic acid in a 1:1 molar ratio, dispersing the encapsulated caffeine throughout at least a portion of a base composition, the encapsulated caffeine being included in an amount sufficient to release 50 mg to 200 mg of caffeine when consumed, and adding at least one pH adjusting agent to the base composition to maintain a pH of the base composition within a range between 2 and 5.
