Methods to Enhance Emulsification of Plant Proteins
Plant protein emulsification presents specific technical hurdles at the molecular level. Current methods achieve oil droplet sizes ranging from 2-10 microns, but stability remains a challenge as proteins often denature under processing conditions, particularly at temperatures above 70°C or when exposed to mechanical shear. Field measurements show that conventional plant protein emulsifiers require ratios of 0.08-0.12 parts protein to oil for stable emulsions - significantly higher than animal-derived alternatives.
The fundamental challenge lies in maintaining protein functionality through processing while achieving the small, uniform droplet sizes and interfacial properties needed for long-term emulsion stability.
This page brings together solutions from recent research—including controlled sol-gel transitions in protein hydrogels, cellulose-derived emulsifiers from agricultural residues, optimized pea protein isolates with defined molecular weights, and novel oleogel systems. These and other approaches focus on practical implementation in food systems while meeting clean-label requirements.
