Crystalline Shell Emulsion for Reduced Fat Food Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-in-oil emulsions used in reduced fat food products are not sufficiently stable to withstand the physical stresses associated with food preparation and manufacturing processes.
Innovation Solution
The development of a stable water-in-oil emulsion where the aqueous phase is individually encased in crystalline shells comprising crystalline monoacylglycerols and triacylglycerols, with the monoacylglycerols and triacylglycerols having a higher crystallization temperature than the continuous fat phase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If water-in-oil emulsion is used to reduce fat content in food products, then fat content is reduced, but emulsion stability deteriorates
Solution Approach 1:
The patent changes the physical state of the emulsifier from liquid to crystalline by selecting monoacylglycerols and triacylglycerols with specific high crystallization temperatures (at least 10°C higher than the continuous fat phase). This parameter change enables the formation of a rigid crystalline shell that provides mechanical stability to the emulsion droplets, resolving the stability issue while maintaining reduced fat content
Solution Approach 2:
The patent creates a composite structure by combining crystalline monoacylglycerols and crystalline triacylglycerols in specific ratios (0.1-10 wt% MAG and 0.1-5 wt% TAG) within the crystalline shell. This composite material approach leverages the complementary properties of both emulsifiers to form a stable, mechanically robust shell that can withstand food processing stresses
2Reliability
If conventional emulsifiers are used to stabilize emulsion, then emulsion stability improves, but resistance to mechanical stresses deteriorates
Solution Approach 1:
The patent exploits the phase transition of monoacylglycerols and triacylglycerols from liquid to crystalline state during cooling. This phase transition creates a solid crystalline shell around the emulsion droplets, transforming the emulsion structure from soft and mechanically weak to rigid and stress-resistant, while maintaining thermodynamic stability
Solution Approach 2:
The patent creates a thin crystalline shell film around each emulsion droplet that acts as a protective barrier. This shell is flexible enough to accommodate droplet deformation during mechanical processing but rigid enough to prevent coalescence and maintain structural integrity under stress

Function Achieved in This Case
The emulsion achieves enhanced stability, allowing it to withstand the mechanical and physical stresses of food manufacturing and maintain stability throughout the shelf-life of the product.
Implementation Method 1
one or more of the droplets is individually encased in a crystalline shell comprising crystalline monoacylglycerols and crystalline triacylglycerols, wherein the monoacylglycerols and the triacylglycerols each or together have a higher crystallization temperature than the continuous fat phase
