Fat Composition Cool Melting Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Confectionery products with reduced saturated fatty acid (SAFA) content typically experience softer textures and altered melting profiles, compromising the cool melting sensation and sensory experience.
Innovation Solution
A fat composition with less than 45 wt.% SAFA, characterized by a significant change in solid fat content from N35 to N25 (at least 15%), providing a sharp melting profile between 25-35°C and a low N35 value, is developed. This composition is non-trans and non-hydrogenated, comprising a blend of palm mid fraction, shea stearin, and liquid oil, which enhances the cool melting sensation while reducing the 'waxy' mouthfeel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If saturated fatty acid (SAFA) content is reduced to improve nutritional value, then health benefits are improved, but cool melting sensation and textural properties deteriorate
Solution Approach 1:
The patent applies parameter changes by precisely controlling the solid fat content profile at specific temperature points (N20, N25, N35) and adjusting the triglyceride composition ratios. By changing these physical and compositional parameters, the invention achieves a sharp melting curve that provides cool melting sensation while maintaining lower SAFA content (less than 45 wt.%).
Solution Approach 2:
The invention uses composite materials by combining specific triglyceride types (POP, StOSt, MPP, MPL, SSS) in defined ratios within the fat composition. This composite approach allows optimization of both nutritional properties (lower SAFA) and sensory properties (cool melting effect) through the synergistic interaction of different triglyceride molecules with specific melting characteristics.
2Object-affected harmful factors
If saturated fatty acid (SAFA) content is reduced to improve nutritional value, then health benefits are improved, but textural properties and product firmness deteriorate
Solution Approach 1:
The patent maintains textural properties by controlling the N20 value (solid fat content at 20°C) to be at least 20%, which ensures sufficient firmness and texture. This parameter control allows the product to maintain desirable textural properties despite reduced SAFA content, resolving the contradiction between health benefits and texture quality.
Solution Approach 2:
The invention applies local quality by creating different functional zones within the fat composition: certain triglycerides (like StOSt and POP) provide structural support and firmness at lower temperatures, while others contribute to melting characteristics. This localized functional distribution allows simultaneous achievement of good texture and cool melting effect.
3Object-affected harmful factors
If saturated fatty acid (SAFA) content is reduced to improve nutritional value, then health benefits are improved, but melting profile and sensory experience deteriorate
Solution Approach 1:
The patent achieves a sharp melting profile by controlling the difference between N35 and N25 values to be at least 15, and setting N35 to less than 3. These parameter specifications ensure that the fat composition melts sharply in the mouth (providing cool sensation) while maintaining stability at storage temperatures, thus resolving the contradiction between nutritional value and melting profile.
Solution Approach 2:
The invention replaces the traditional reliance on high SAFA content for achieving firm texture and controlled melting with a different mechanism based on triglyceride composition and solid fat content profiling. By substituting the mechanical/structural role of saturated fats with carefully selected triglyceride combinations, the invention achieves similar functional outcomes with improved nutritional properties.

Function Achieved in This Case
The fat composition achieves a very cool melting sensation in confectionery products, maintaining desirable textural properties despite reduced SAFA levels, offering a unique sensory experience compared to similar compositions with higher SAFA content.
Implementation Method 1
the change in solid fat content from N35-N25 for the composition is at least 15... the composition typically shows a sharp melting profile in the region 25-35 deg C... cool melting sensation
Implementation Method 2
N-values (Solid Fat content (SFC)) as described herein are typically determined using NMR spectroscopy according to the IUPAC 2.150b method
