Solution Overview

Problem

Existing whey protein beverages often have a yellow color that negatively impacts consumer perception and stability, and traditional bleaching methods can affect taste and protein structure.

Innovation Solution

A packaged, heat-treated beverage preparation with a pH of 5.5-8.0 and 1-20% protein concentration, where at least 85% of the protein is beta-lactoglobulin (BLG), is produced through pasteurization to achieve a neutral color and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If traditional chemical bleaching using hydrogen peroxide is applied to remove yellow color, then color neutrality is improved, but taste quality deteriorates and protein structure stability worsens

Engineering Contradiction:
Improvecolor neutralityVSAvoidprotein structure stability
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The patent extracts and removes the yellow-colored components (carotenes and other pigments) from whey protein products through filtration and separation processes, achieving color neutrality without adding chemical bleaching agents that would compromise protein structure or taste quality

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses enzymatic treatment with proteases as an intermediary process to break down pigmented compounds into smaller, colorless peptides and amino acids, thereby removing yellow color while preserving protein functionality and taste, avoiding direct chemical bleaching

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If whey proteins are incorporated for nutritional benefits, then nutritional value is improved, but yellow color appears that negatively impacts consumer perception

Engineering Contradiction:
Improvenutritional valueVSAvoidcolor appearance
Core Design Contradiction:
Quantity of substanceVSIllumination intensity

Solution Approach 1:

The patent selectively removes yellow-colored carotene pigments and other chromophores from whey protein products through adsorption, filtration, and separation techniques, while retaining the full nutritional profile including proteins, vitamins, and minerals

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies physical and enzymatic methods to transform the yellow coloration of whey products into neutral or white appearances, using processes such as enzymatic degradation of pigments, adsorption on activated carbon, and membrane filtration, thereby improving consumer acceptance without compromising nutritional content

Inventive Principle:
Principle #32Color changes
