Citric-Phosphoric Acid Blend Reduces Sports Drink Aftertaste

Solution Overview

Problem

Conventional sports beverages often have an excessive aftertaste, leading to inadequate consumption and taste burnout among athletes, and lack improved gulpability.

Innovation Solution

A non-carbonated sports beverage composition utilizing a novel acidulant blend of citric acid and phosphoric acid in a specific ratio, reducing aftertaste and enhancing gulpability, comprising water, electrolytes, carbohydrates, non-nutritive sweeteners, flavoring agents, and a pH range of 2.5 to 4.5, which stimulates consumption and rapid drinking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional sports beverages use traditional acidulants (citric acid only), then the beverage provides basic tartness, but the aftertaste becomes excessive and unpleasant

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent applies composite materials by combining citric acid and phosphoric acid in a specific ratio (3:1 to 5:1) to create a blended acidulant system. This composite acidulant blend produces a synergistic effect that reduces aftertaste compared to using citric acid alone, while maintaining the necessary tartness and pH control for sports beverage stability.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the chemical composition parameters by introducing phosphoric acid alongside citric acid, and adjusts the concentration ratio between them. This parameter modification transforms the taste profile by reducing the excessive aftertaste associated with conventional citric acid-only formulations, while maintaining effective pH control in the 2.5-4.5 range.

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If sports beverages have adequate carbohydrate and electrolyte content, then nutritional replacement is achieved, but the beverage becomes less palatable and gulpability decreases

Engineering Contradiction:
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent modifies the taste parameters by implementing a specific acidulant blend ratio (citric acid:phosphoric acid = 3:1 to 5:1) and controlling pH within 2.5-4.5. These parameter changes optimize the balance between nutritional content and palatability, making high-carbohydrate, high-electrolyte beverages more gulpable by reducing aftertaste fatigue.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The composite acidulant system creates a more balanced taste profile that complements the carbohydrate and electrolyte components. This composite approach ensures that the beverage remains palatable during rapid consumption, allowing athletes to gulp larger volumes without experiencing taste burnout.

Inventive Principle:
Principle #40Composite materials

3Stability of the object's composition

If sports beverages maintain stable pH for shelf life, then product stability is improved, but aftertaste increases and consumption decreases

Engineering Contradiction:
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The patent uses a composite buffer system comprising citric acid and phosphoric acid that provides superior pH stability compared to citric acid alone. This composite buffering system maintains consistent pH levels during shelf storage and consumption, preventing the pH drift that leads to aftertaste development, while the specific 3:1 to 5:1 ratio optimizes both stability and taste.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent adjusts the pH parameter to a specific range (2.5-4.5) using the blended acidulant system, which provides optimal balance between shelf stability and taste quality. This parameter optimization ensures that the beverage maintains stable composition over time without developing excessive aftertaste, thereby improving both longevity and consumability.
