Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand for healthier dietary alternatives with lower fat content and improved textural and sensory characteristics in foam-based food products, such as ice cream, due to the complexity of colloidal systems and the adverse effects of high fat on melt, stability, and texture.
Innovation Solution
A formulation comprising a monoglyceride and a fatty acid salt, combined to form a liquid crystalline lamellar phase above the Krafft temperature and a solid crystalline phase below, which is used to create a structuring agent for foam-based products, enhancing stability and reducing fat content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high fat content is used in foam-based food products, then structure retention and premature melt prevention are improved, but textural quality and stability deteriorate
Solution Approach 1:
The patent changes the chemical parameters of the fat phase by using specific monoglyceride combinations (GMO/GMP) with controlled molecular weights and saturation levels. This allows optimization of the fat network structure to achieve both strength and stability without increasing overall fat content, resolving the contradiction between structure retention and stability.
Solution Approach 2:
The patent creates a composite emulsion system combining monoglycerides with milk proteins (casein, whey) and starch derivatives. This composite approach allows the different components to work synergistically - monoglycerides provide structural framework while proteins and starches enhance stability and texture, resolving the contradiction between structure and stability.
2Reliability
If additional MSNF sources are added to provide sufficient stabilization, then foam creation and air bubble stability are improved, but product complexity and processing difficulty increase
Solution Approach 1:
The patent uses monoglycerides that perform multiple functions simultaneously: they act as emulsifiers for fat-water interfaces, stabilize air bubbles through interfacial film formation, and contribute to the fat network structure. This multi-functionality reduces the need for additional separate stabilization agents, resolving the contradiction between air bubble stability and product complexity.
3Stability of the object's composition
If more stabilizers and emulsifiers are used to maintain homogeneity and integrity, then phase separation prevention is improved, but manufacturing cost and processing complexity increase
Solution Approach 1:
The patent merges the functions of multiple stabilizers and emulsifiers into a single integrated monoglyceride-based system. The monoglycerides work in conjunction with native milk components to provide combined emulsification, foam stabilization, and phase separation prevention, reducing the number of separate ingredients and simplifying manufacturing while maintaining homogeneity.

Implementation Method 2
To form a stable foam, a surfactant, monoglycerides or proteins, must be present to reduce the interfacial tension between the gaseous phase and the aqueous phase
Implementation Method 3
heating a mixture of a monoglyceride and fatty acid salt to a temperature above the Krafft temperature of the monoglyceride and fatty acid salt to form a solution comprising a lamellar structure in a liquid crystalline state
