Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to form intermolecular compounds using combinations of saturated and unsaturated fatty acid triglycerides, limiting their application in foods such as chocolates and margarine, where these compounds could enhance texture and prevent blooming.
Innovation Solution
Formation of intermolecular compounds through melt mixing di-saturated medium chain fatty acids mono-saturated long chain fatty acid triglycerides and 1,3-di-saturated long chain fatty acids 2-mono-unsaturated long chain fatty acid triglycerides, with specific fatty acid structures and preparation methods, achieving long spacing values of 65 Å or more by X-ray diffraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If St-U-St type triglyceride and St-St-St type triglyceride are combined, then the variety of triglyceride compositions is increased, but intermolecular compounds cannot be formed and eutectic crystals are formed instead
Solution Approach 1:
The invention changes the molecular structure parameters of the triglycerides by introducing medium-chain fatty acids (6-12 carbon atoms) at specific positions (sn-1 and sn-3) while maintaining long-chain fatty acids (16-24 carbon atoms) at the sn-2 position. This specific parameter configuration enables intermolecular compound formation between St-U-St and St-St-St types, resolving the contradiction between composition variety and reliable compound formation.
Solution Approach 2:
The invention creates composite triglyceride molecules with specific hybrid structures combining medium-chain and long-chain fatty acids in defined arrangements. These composite molecular structures enable the formation of stable intermolecular compounds that exhibit both the versatility of different triglyceride types and the reliability of consistent crystal formation with long spacing values of 65 Å or more.
2Ease of manufacture
If conventional triglyceride combinations are used in foods, then the existing flavor and texture are maintained, but blooming occurs and crystal precipitation requires frequent preservation methods
Solution Approach 1:
The invention replaces the need for frequent preservation methods with a self-stabilizing triglyceride structure. The specific molecular configuration (medium-chain at sn-1/sn-3, long-chain at sn-2) creates intermolecular compounds that inherently resist blooming and crystal precipitation, eliminating the need for continuous preservation interventions and simplifying food processing.
Solution Approach 2:
By changing the fatty acid chain length parameters and their positional arrangements in the triglyceride molecules, the invention achieves a stable crystal structure with long spacing values (65 Å or more). This parameter modification provides inherent stability that prevents blooming and eliminates the need for frequent preservation methods, directly addressing the reliability issue while maintaining ease of manufacture.
3Ease of manufacture
If ester exchange reaction is conducted to produce specific triglycerides, then the fat structure is reformulated, but intermolecular compounds still cannot be formed
Solution Approach 1:
The invention specifies precise parameter changes in the ester exchange reaction: using 1,3-specific lipase to produce triglycerides with medium-chain fatty acids (6-12 carbon atoms) at sn-1 and sn-3 positions and long-chain fatty acids (16-24 carbon atoms) at the sn-2 position. This exact parameter configuration enables subsequent intermolecular compound formation, resolving the contradiction between manufacturability and compound formation reliability.
Solution Approach 2:
The invention uses 1,3-specific lipase as an intermediary enzyme that catalyzes the selective ester exchange reaction to produce the specific triglyceride structure required for intermolecular compound formation. This intermediary biological tool enables the transformation of conventional triglycerides into the specialized structures (with medium-chain and long-chain fatty acids in specific arrangements) that can form stable intermolecular compounds.

AI summary
There are provided an intermolecular compound of (a) di-saturated medium chain fatty acids mono-saturated long chain fatty acid triglyceride and (b) 1,3-di-saturated long chain fatty acids 2-mono-unsaturated long chain fatty acid triglyceride, of which a long spacing value by X-ray diffraction is 65 Å or more, and foods containing the intermolecular compound. The intermolecular compound can be used as a part of fats and oils that constitute foods. Due to formation of the intermolecular compound, the fats and oils containing large amounts of symmetric triglycerides such as cocoa butter and those containing medium chain fatty acids do not form separate crystals and, therefore, can keep smooth texture and prevent blooming.
