Foam Control Additives for Carbonated Beverages

Solution Overview

Problem

The food and drink industry faces challenges with excessive foaming and gas loss in carbonated beverages during manufacturing, filling, and dispensing, particularly with aspartame-containing drinks, leading to inefficiencies and a decrease in drinking quality.

Innovation Solution

A process involving the use of additives like polyoxyethylene sorbitan fatty acid esters or polyethylene glycol esters to control foam persistence and gas retention, which coat gas bubbles to inhibit coalescence and reduce gas release, thereby maintaining the fizz and quality of beverages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If mechanical and physical means (heating, centrifuging, spraying, ultrasound) are used to combat foaming, then foam control is achieved, but process complexity and energy consumption increase

Engineering Contradiction:
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent introduces chemical foam control agents as intermediaries that adsorb at gas-liquid interfaces to reduce surface tension and prevent foam formation. These agents act as mediators between the carbonated beverage and the foaming phenomenon, providing effective foam control through chemical interaction rather than complex mechanical processes

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent modifies the chemical parameters of the beverage system by adding foam control agents with specific molecular structures and surface properties. This changes the interfacial tension parameters and foam stability characteristics, achieving foam control through parameter modification rather than process complexity

Inventive Principle:
Principle #35Parameter changes

2Object-generated harmful factors

If chemical foam control agents are used, then foaming is reduced, but gas loss from the beverage increases

Engineering Contradiction:
Core Design Contradiction:
Object-generated harmful factorsVSLoss of substance

Solution Approach 1:

The patent carefully selects and optimizes the concentration and molecular weight parameters of foam control agents to achieve foam suppression while minimizing gas loss. By adjusting these parameters, the system finds an optimal balance where foam control is effective but gas retention is maintained

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite foam control formulations containing multiple ingredients with complementary functions. These composite systems provide both foam control and gas retention benefits, addressing the contradiction by combining materials that work synergistically rather than using single agents

Inventive Principle:
Principle #40Composite materials

3Object-generated harmful factors

If conventional foam control agents are used in aspartame-containing beverages, then foaming is reduced, but foam persistence increases and drinking quality decreases

Engineering Contradiction:
Core Design Contradiction:
Object-generated harmful factorsVSDuration of action of stationary object

Solution Approach 1:

The patent modifies the molecular weight and hydrophilic-lipophilic balance (HLB) parameters of foam control agents to achieve rapid foam breakdown. Specifically, agents with molecular weights in certain ranges and optimized HLB values provide both foam suppression and quick foam collapse, improving drinking quality

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces specially selected foam control agents that act as intermediaries with specific affinity for aspartame-containing systems. These agents interact with the aspartame-beverage matrix to provide effective foam control without creating persistent foam, maintaining compatibility with the beverage composition

Inventive Principle:
Principle #24Intermediary (Mediator)

4Manufacturing precision

If no foam control measures are taken, then beverage quality is maintained, but filling efficiency decreases due to excessive foaming

Engineering Contradiction:
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent applies foam control agents before the filling process to prevent excessive foaming during filling. This preliminary action ensures that the beverage is pre-conditioned to minimize foam formation, allowing efficient filling operations while maintaining beverage quality

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The foam control agent serves as an intermediary that enables both quality maintenance and efficiency improvement. By introducing this chemical mediator, the system achieves a state where filling can proceed efficiently without compromising beverage quality through excessive foaming

Inventive Principle:
Principle #24Intermediary (Mediator)
