Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food products lack effective, plant-based emulsifiers that provide stability and viscosity in emulsions, particularly in confectionary spreads and ice creams, with current alternatives like pulse flour and protein isolates showing limitations in performance and stability.
Innovation Solution
Heat moisture treatment of fava bean protein concentrates denatures proteins and gelatinizes starch, creating aggregated particles that function as superior emulsifiers, enhancing emulsion stability and viscosity in food products like confectionary spreads and ice creams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pulse flour and protein isolates are used as emulsifiers, then plant-based emulsification is achieved, but emulsion stability and viscosity are insufficient
Solution Approach 1:
The patent applies heat-moisture treatment to fava bean protein concentrate, changing its physical and chemical parameters through controlled heating (typically 60-120°C) and moisture content adjustment (10-50%). This treatment denatures proteins and gelatinizes starch, transforming the emulsifier's properties to achieve superior emulsion stability and viscosity compared to untreated plant proteins
Solution Approach 2:
The heat-moisture treated fava bean protein concentrate creates a composite structure where denatured proteins and gelatinized starch work synergistically. The protein matrix provides emulsifying capability while the gelatinized starch contributes to viscosity and stability, forming a composite emulsifier system that outperforms single-component plant proteins
2Reliability
If heat moisture treatment is applied to fava bean protein concentrate, then emulsifying capability and viscosity are improved, but processing complexity increases
Solution Approach 1:
The heat-moisture treatment is performed as a preliminary processing step on the fava bean protein concentrate before its use as an emulsifier. By pre-denaturing proteins and pre-gelatinizing starch in the protein concentrate manufacturing stage, the material is prepared in advance to deliver superior emulsifying performance without requiring additional treatment steps during final product formulation
Solution Approach 2:
The heat-moisture treatment process enables the fava bean protein concentrate to self-regulate its emulsifying properties. The treated protein matrix automatically provides optimal viscosity and emulsion stability through its transformed structure, reducing the need for additional additives or complex formulation adjustments in downstream applications
