Microalgal Protein Emulsifier for Oil-in-Water Dressing Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-oil emulsified food products, such as mayonnaise and salad dressings, face stability issues when using plant protein emulsifiers, leading to inhomogeneous texture and increased viscosity over time, which is not acceptable for industrially produced products aiming for consistent quality and appearance similar to egg-derived emulsifier-based products.
Innovation Solution
A food composition comprising 66-87% vegetable oil, less than 1% microalgal oil, 0.01-2% microalgal protein, and a pH of 2-4.8, where microalgal protein acts as the sole emulsifier, ensuring stability, homogeneity, and viscosity consistency for at least a month, similar to egg-derived emulsifier-based products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plant protein emulsifiers are used to stabilize high-oil emulsions, then egg-free stability is achieved, but the texture becomes inhomogeneous and curdled
Solution Approach 1:
The patent changes the chemical composition parameters by using microalgal protein instead of conventional plant proteins (pea, soy, wheat). This parameter substitution resolves the contradiction by providing emulsification capability without the curdling effect, achieving both stability and texture homogeneity in high-oil emulsions.
2Reliability
If plant protein emulsifiers are used, then egg-free product is achieved, but viscosity increases significantly upon storage
Solution Approach 1:
The patent substitutes conventional plant proteins with microalgal protein, changing the protein source parameter. This resolves the viscosity instability issue during storage while maintaining the egg-free requirement and emulsion stability over extended periods.
3Reliability
If plant protein emulsifiers are used, then egg-free formulation is achieved, but gloss and appearance quality deteriorate
Solution Approach 1:
The patent changes the protein source parameter from conventional plant proteins to microalgal protein, which resolves the appearance quality issue by providing the desired gloss and visual characteristics while maintaining emulsion stability and egg-free formulation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition achieves a stable, homogenous, and glossy texture with constant viscosity, resembling egg-derived emulsifier-based products, maintaining quality for extended storage periods without the need for additional emulsifiers or thickeners.
Implementation Method 1
Emulsified food compositions comprising a continuous water phase wherein oil droplets are dispersed
Implementation Method 2
an emulsifier is present. For mayonnaise or salad dressing, the emulsifier traditionally comprises egg
