Cocoa butter equivalent from lipase-synthesized and fractionated fats
Developing a cocoa butter equivalent (CBE) using POP-, POS-, and SOS-rich fats produced through enzymatic synthesis and fractionation. This CBE is fully compatible with cocoa butter, ideal for use in chocolates and confectionery products.
Overview
This innovative research focuses on creating a cocoa butter equivalent (CBE) by blending fats rich in specific triacylglycerols: POP, POS, and SOS. These fats are synthesized and fractionated using lipase-catalyzed reactions, resulting in a CBE that mirrors the physicochemical properties of natural cocoa butter. The CBE offers a sustainable and cost-effective alternative for use in chocolates and other confectionery products without compromising quality.
Technical specifications
- POP-rich fat: Produced via double-step fractionation of palm oil to achieve 75% purity.
- POS- and SOS-rich fats: Created through two-step enzymatic interesterification and fractionation, reaching 90% purity.
- Blend formulation: Fats are combined in specific ratios to mimic cocoa butter's crystallization, melting profiles, and polymorphism.
- Validation tests: Includes crystallization and melting behavior analysis, solid fat content, slip melting point, and compatibility with cocoa butter.
Technology readiness level
Currently, the technology is at TRL 4, indicating that it has been validated in a laboratory environment. Ongoing research includes optimizing the production of POS-rich fat and testing the CBE in chocolate formulations to further assess performance and compatibility.
