Acid-Stable Particulate Creamer Using Whey Protein and Mild Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing creamers and whiteners suffer from curdling or 'feathering' in acidic environments, particularly when exposed to hot liquids, and often rely on inorganic phosphates, which are undesirable due to their hygroscopic properties and the trend to reduce E-numbers in food products.
Innovation Solution
A particulate creamer or whitener composition is developed using whey protein, an acidulant, and mild processing conditions, including low temperatures and pressures during homogenization and spray-drying, to create a stable product that maintains whitening and creaming power in acidic foodstuffs without inorganic phosphates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If inorganic phosphates are added to prevent curdling in acidic environments, then stability against acid is improved, but hygroscopic properties cause lumping and processing difficulties
Solution Approach 1:
The invention removes inorganic phosphates from the creamer composition entirely, extracting the problematic substance that caused hygroscopic lumping and processing difficulties while maintaining acid stability through alternative means (proper emulsion formulation and mild processing)
Solution Approach 2:
The invention changes the pH parameter during manufacturing by using mild acidification (pH 4.5-6.0) instead of highly acidic conditions, and controls processing temperatures (50-70°C) to prevent casein precipitation while achieving stable acid-resistant creamer without phosphates
2Productivity
If conventional processing temperatures and pressures are used during homogenization and spray-drying, then manufacturing efficiency is improved, but curdling and feathering occur in acidic environments
Solution Approach 1:
The invention modifies processing parameters by using mild temperatures (50-70°C) and controlled pressures during homogenization and spray-drying, preventing casein denaturation and curdling while maintaining manufacturing efficiency through optimized process conditions
3Stability of the object's composition
If inorganic phosphates are used to maintain acid stability, then curdling is prevented, but the product contains artificial ingredients (E-numbers) which are undesirable
Solution Approach 1:
The invention completely removes inorganic phosphates (E-numbers) from the creamer formulation, eliminating artificial ingredients while achieving acid stability through natural emulsion stabilization and controlled processing of dairy components
Solution Approach 2:
The invention uses simple, natural dairy-based components (milk proteins, fats, carbohydrates) processed under controlled conditions to achieve stability, replacing complex chemical additives with straightforward food-grade ingredients
