Solution Overview

Problem

Dairy-based chocolate ready-to-drink beverages face challenges with protein destabilization, phase separation, sedimentation, syneresis, and viscosity changes during storage, especially at elevated temperatures, making them unsuitable for long-term shelf stability and consumer preference.

Innovation Solution

A stabilizing system comprising sodium hexamethaphosphate and a hydrocolloid component, such as carrageenan or cellulose, is used to maintain a consistent viscosity and prevent phase separation, ensuring the beverage remains stable and palatable over extended storage periods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If proteins are added to liquid chocolate beverages to increase nutritional value, then the protein content is improved, but the beverage viscosity increases significantly and physico-chemical instability issues occur

Engineering Contradiction:
Improveprotein contentVSAvoidphysico-chemical stability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent introduces a stabilizing system comprising sodium hexamethaphosphate and hydrocolloid components (such as carrageenan, cellulose, or xanthan gum) as intermediary substances. These stabilizers act as mediators between the protein components and the beverage matrix, preventing direct harmful interactions while maintaining protein functionality. The stabilizing system creates a protective environment that prevents protein aggregation and phase separation, allowing high protein content (4-12% w/w) to be maintained without the usual viscosity increases and instability issues.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs a composite stabilizing system that combines multiple components: sodium hexamethaphosphate (0.01-0.05% w/w) with hydrocolloid components (0.05-0.5% w/w). This composite approach leverages the synergistic effects of different stabilizing mechanisms - the phosphates provide electrostatic stabilization while the hydrocolloids provide steric hindrance and network formation. The combination creates a multi-functional stabilizing system that addresses multiple instability mechanisms simultaneously, enabling high protein content while maintaining beverage stability and acceptable viscosity.

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If proteins are added to chocolate beverages to improve nutritional value, then the protein content is improved, but the beverage texture and mouthfeel become unpleasant

Engineering Contradiction:
Improveprotein contentVSAvoidmouthfeel and texture
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The stabilizing system components act as intermediaries that prevent direct aggregation of protein molecules and particles. Sodium hexamethaphosphate provides electrostatic repulsion between protein molecules, while hydrocolloid components form a protective network that prevents protein-protein interactions. This mediation ensures that even at high protein concentrations (4-12% w/w), the beverage maintains a smooth, homogeneous texture and pleasant mouthfeel, avoiding the gritty or clumpy textures that would otherwise occur.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If cocoa particles are suspended in high-protein beverages to maintain homogeneity, then the beverage uniformity is improved, but phase separation and sedimentation occur during storage

Engineering Contradiction:
Improvebeverage homogeneityVSAvoidresistance to phase separation
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The stabilizing system serves as a protective intermediary that prevents direct contact and aggregation between cocoa particles and protein molecules. The hydrocolloid components form a steric barrier around particles, while sodium hexamethaphosphate provides electrostatic repulsion. This dual mechanism prevents cocoa particles from aggregating with proteins or each other, maintaining uniform suspension even during extended storage at elevated temperatures (up to 38°C for 1 month).

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The composite stabilizing system combines electrostatic stabilization (sodium hexamethaphosphate) with steric hindrance (hydrocolloid components) to create a multi-layered protective barrier around cocoa particles and protein aggregates. This composite approach addresses multiple mechanisms of phase separation simultaneously - preventing particle aggregation, creaming, and sedimentation. The synergistic effect of the phosphates and hydrocolloids creates a robust stabilizing network that maintains beverage homogeneity throughout the shelf life.

Inventive Principle:
Principle #40Composite materials

4Reliability

If heat treatment is applied to sterilize the beverage, then the aseptic stability is improved, but protein destabilization and coagulation occur

Engineering Contradiction:
Improveaseptic stabilityVSAvoidprotein stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The stabilizing system is incorporated into the beverage formulation before heat treatment to provide protective cushioning against thermal stress. The hydrocolloid components and sodium hexamethaphosphate create a protective network and electrostatic barrier that cushions the protein molecules against denaturation and aggregation during pasteurization or sterilization processes. This beforehand protection allows the beverage to withstand standard heat treatment (e.g., 15-30 minutes at 70-90°C or UHT treatment) without significant protein destabilization or coagulation.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The stabilizing system acts as an intermediary protective layer between the heat treatment process and the protein components. During thermal processing, the hydrocolloid network and phosphates mediate the thermal stress, absorbing and distributing heat energy while preventing direct thermal damage to protein molecules. This intermediary protection enables aseptic sterilization while maintaining protein stability and preventing heat-induced coagulation.

Inventive Principle:
Principle #24Intermediary (Mediator)
