Non-Hydrogenated Emulsifier Composition for Stable Emulsions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved emulsifiers that can be readily produced from convenient sources and that increase the stability of emulsions against separation into their constituent phases, as existing emulsifiers often lack sufficient stability and are derived from hydrogenated or palm-based sources.
Innovation Solution
A non-hydrogenated, non-palm emulsifier composition is developed by reacting a fatty acid composition comprising at least 80% free fatty acids with glycerol, resulting in a mixture with specific fatty acid profiles, including stearic, oleic, and palmitic acids, to produce monoglycerides, diglycerides, and triglycerides, which are suitable for use in food and cosmetic applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional emulsifiers are used, then emulsification function is provided, but emulsion stability against separation is insufficient
Solution Approach 1:
The patent changes the chemical composition parameters of the emulsifier by specifying precise ranges of monoglycerides (20-80 wt%), diglycerides (20-60 wt%), and triglycerides (0-20 wt%), along with specific fatty acid profiles (stearic acid 30-70%, oleic acid 20-40%, palmitic acid 5-20%). This parameter optimization resolves the contradiction by achieving both adequate emulsification function and improved emulsion stability against separation.
2Ease of manufacture
If hydrogenated or palm-based sources are used for emulsifier production, then sufficient emulsifying properties are achieved, but sustainability and trans fatty acid concerns arise
Solution Approach 1:
The patent extracts and eliminates harmful elements (hydrogenation process and palm-based sources) from the emulsifier production while maintaining the desired emulsifying properties. By specifying non-hydrogenated sources and particular fatty acid compositions (low palmitic acid content), the invention removes trans fatty acid concerns while preserving manufacturing feasibility through defined production methods.
3Reliability
If specific fatty acid compositions are used, then emulsifier performance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent defines specific parameter ranges for fatty acid compositions (stearic acid 30-70%, oleic acid 20-40%, palmitic acid 5-20%) that optimize emulsifier performance. These parameter specifications balance performance improvement with manufacturing feasibility by providing clear, achievable targets for producers without requiring overly complex processing steps.
