Randomly Interesterified Fat Composition for Temper-Free Chocolate Gloss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interesterified oils and/or fats used in chocolates may generate soapy flavor due to hydrolysis of lauric fat, affecting the shelf life and gloss maintenance, and existing compositions do not effectively improve chocolate gloss without tempering operations.
Innovation Solution
A randomly interesterified oil and/or fat composition comprising 6.5 to 20% saturated fatty acid with 20 or more carbon atoms, 40 to 70% unsaturated fatty acid with 18 carbon atoms, and 13 to 35% saturated fatty acid with 18 carbon atoms, blended in 2 to 10% in chocolates, using a chemical or enzymatic catalyst for random interesterification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If lauric fat is used to improve gloss of chocolates, then the gloss can be maintained, but soapy flavor is generated due to hydrolysis, affecting shelf life
Solution Approach 1:
The patent extracts and removes lauric acid (a saturated fatty acid with 12 carbon atoms) from the oil and/or fat composition used in chocolate production. By specifically excluding lauric acid while maintaining other saturated fatty acids with 20 or more carbon atoms, the invention prevents the formation of soapy flavor during storage while preserving the gloss-maintaining properties of the chocolate.
2Stability of the object's composition
If interesterified oil and/or fat is used to improve gloss, then gloss can be maintained, but the composition requires specific fatty acid ranges that may compromise flavor stability
Solution Approach 1:
The patent applies parameter changes by precisely controlling the fatty acid composition within specific ranges: saturated fatty acids with 20 or more carbon atoms (6.5-20 mass%), unsaturated fatty acids with 18 carbon atoms (40-70 mass%), and saturated fatty acids with 18 carbon atoms (13-35 mass%). This optimized parameter range achieves both gloss maintenance and flavor stability without requiring tempering operations.
3Device complexity
If chocolate is produced without tempering operation to simplify process, then manufacturing complexity is reduced, but gloss and quality deterioration occur over time
Solution Approach 1:
The patent applies preliminary action by pre-formulating the oil and/or fat composition with an optimized fatty acid profile before incorporating it into the chocolate. This preliminary optimization of the fat composition enables the chocolate to maintain gloss and quality without requiring subsequent tempering operations, thus simplifying the overall manufacturing process while ensuring product stability.

Implementation Method 1
using a chemical or enzymatic catalyst for random interesterification
Implementation Method 2
when lauric fat, which has 12 carbon atoms, is hydrolyzed, so-called soapy flavor may be generated
