POS-Rich Fat Production via Enzymatic Transesterification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cocoa butter equivalents (CBEs) often have hard textures, leave aftertastes, and can cause blooming due to high SOS content, failing to replicate the soft meltability and freshness of natural cocoa butter.
Innovation Solution
A method involving enzymatic transesterification of vegetable fat to produce a fat with a high content of 1-palmitoyl-2-oleyl-3-stearoyl glycerol (POS) by mixing palm oil or its fraction with stearic acid, using enzymes from Mucor miehei or Thermomyces lanuginosus, followed by fractionation and removal of crystallized fractions to achieve a POS content of 50% or higher, without using solvents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional CBEs with high SOS content are used, then solid fat content at room temperature is improved, but meltability and mouthfeel deteriorate
Solution Approach 1:
The invention changes the triglyceride composition parameters by increasing POS content to 40-60% and controlling SOS content to 10-30%, which fundamentally alters the melting characteristics and mouthfeel properties of the CBE while maintaining adequate solid fat content
Solution Approach 2:
The invention creates a composite triglyceride structure combining multiple types (POP, POS, SOS) in specific ratios, where the synergistic effect of these composite components achieves both proper solid fat content and excellent meltability that cannot be obtained by single triglyceride types
2Reliability
If natural CBEs such as Sal fat and Shea butter are used, then compatibility with cocoa butter is improved, but supply stability and cost control deteriorate
Solution Approach 1:
The invention copies the desirable properties of natural CBEs (triglyceride composition profile) through synthetic production methods, creating an artificial substitute that replicates the functional characteristics without relying on natural source variability
Solution Approach 2:
The invention uses readily available and inexpensive raw materials (palm oil, stearic acid) that can be consistently sourced, replacing expensive and scarce natural CBEs with a cost-effective synthetic alternative
3Ease of operation
If enzymatic transesterification is used to produce POS-rich fat, then meltability is improved, but production complexity increases
Solution Approach 1:
The invention uses enzymes as biological catalysts (intermediaries) to facilitate the transesterification reaction, enabling selective formation of POS triglycerides under mild conditions without requiring complex high-energy equipment or multi-step synthetic procedures

AI summary
The present invention relates to a method of manufacturing a hard butter similar to cacao butter, the method comprising the steps of: mixing vegetable fats and oils, fatty acids, and fatty acid derivatives; performing enzymatic transesterification; performing fractionation using physical properties; and removing fatty acids and fatty acid derivatives through distillation. The high-POS-containing fat and oil manufactured by the method of the present invention contains high POS content of a triglyceride composition using raw materials of palm oil-based vegetable fat and oil, exotic fat-based vegetable olein oil or sunflower oil-based vegetable fat and oil. Therefore, the high-POS-containing fat and oil manufactured by the method of the present invention has properties different from typical fats replacing cacao butter, and have the same physical properties and composition as high-quality natural cacao butter. Thus, the fat and oil composition manufactured by the method of the present invention can replace natural cacao butter on a 1:1 basis.
