Enzymatic interesterification for cocoa butter substitutes using palm olein
Develop cocoa butter substitutes with enhanced thermal resistance and cost-effectiveness by enzymatic interesterification of palm olein and palm kernel hardfat. This method improves oxidative stability and eliminates polymorphic transition issues.
Overview
This research proposes the development of cocoa butter substitutes through enzymatic interesterification. By utilizing palm olein and fully hydrogenated palm kernel oil (palm kernel hardfat), the project aims to create symmetrical triacylglycerols for use in chocolate products. These substitutes promise enhanced thermal resistance and cost-effectiveness, addressing common issues like polymorphic transitions. The focus is on achieving a stable and compatible triacylglycerol composition for direct application in various products.
Technical specifications
Key features:
- Utilizes enzymatic interesterification as an alternative to chemical catalysts, avoiding hazardous chemicals and post-clarification processes.
- Employs commercial lipase Lipozyme TL IM to interesterify binary mixtures of palm olein and palm kernel hardfat.
- Evaluates the impact on composition, physical properties, and crystallization, focusing on triacylglycerol composition, thermal behavior, and solids profile.
- The process preserves natural regiospecificity and enhances the oxidative stability of the fats.
Technology readiness level
This technology is currently at TRL 2, indicating that the concept and application are formulated, with plans for further validation through experimental methodologies. Future work will involve characterizing raw materials, preparing mixtures, and assessing interesterification effects on fat properties.
