Hydrolyzed Plant Protein Emulsifier for Stable Oil-in-Water Dressings

The patent applies parameter changes by modifying the protein structure through controlled hydrolysis to achieve optimal emulsification properties. The protein is hydrolyzed to a specific degree (2-10% degradation) to create peptides that provide both stability and glossiness, resolving the contradiction between these two properties.

The patent uses composite materials by combining hydrolyzed plant protein with specific ratios of vegetable oil and water to create an emulsion system that achieves both stability and glossiness. The composite formulation allows the protein peptides to interact with both oil and water phases effectively.

The patent replaces expensive and non-plant-based egg-derived emulsifiers with plant-based protein alternatives that can be easily substituted. The hydrolyzed plant protein serves as a versatile, plant-based emulsifier that maintains functionality without relying on animal products.

The patent modifies plant protein through controlled hydrolysis to change its functional properties, enabling it to perform the emulsification function traditionally associated with egg yolk. This parameter change allows plant-based proteins to achieve comparable stability and glossiness.

The patent optimizes the degree of protein hydrolysis to a specific range (2-10%) where the emulsifier provides sufficient stability at low concentrations. This parameter optimization reduces the amount of emulsifier needed, minimizing taste impact and production costs while maintaining stability.

The patent creates local quality by generating specific peptide structures through controlled hydrolysis that are particularly effective at the oil-water interface. These locally optimized peptide structures provide high emulsification efficiency at low concentrations, reducing overall emulsifier levels needed.
