Butterfat-Mimicking Fat Formulation With Target Melting Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substitute fats, particularly those derived from plant-based sources, often fail to accurately mimic the properties of animal fats, leading to poor performance in terms of mouthfeel, texture, and flavor, and there is a need for sustainable, low-carbon footprint alternatives to traditional dairy fats.
Innovation Solution
A fat formulation comprising lipids with specific fatty acid distributions, including nonmonotonically increasing distributions with gaps or peaks, and optionally additives, is developed to mimic the thermal and mechanical properties of dairy fats, using chemical processes to produce a composition that closely resembles dairy fats in terms of melting profiles, texture, and flavor.

1Object-affected harmful factors
If plant-based substitute fats are used, then carbon footprint is reduced, but mouthfeel and texture quality deteriorate
Solution Approach 1:
The patent applies parameter changes by precisely controlling the fatty acid composition parameters of the substitute fat. Specifically, it formulates a lipid composition with C8:0 (caprylic acid) at 10-20%, C10:0 (capric acid) at 20-30%, C12:0 (lauric acid) at 10-20%, and C14:0 (myristic acid) at 20-30%, which mimics the thermal and mechanical properties of dairy fats while using sustainable plant-based or alternative sources.
Solution Approach 2:
The patent uses composite materials by combining multiple fatty acid components in specific proportions to create a substitute fat that replicates the complex properties of dairy fats. The composite lipid composition includes a blend of medium-chain and long-chain saturated fatty acids, achieving both sustainability and sensory quality.
2Ease of manufacture
If conventional substitute fats are used, then production is simpler, but thermal and mechanical properties similar to dairy fats are not achieved
Solution Approach 1:
The patent achieves manufacturing precision by specifying exact parameter ranges for fatty acid composition (C8:0 10-20%, C10:0 20-30%, C12:0 10-20%, C14:0 20-30%) and solid fat content at different temperatures, which can be controlled through standard lipid processing techniques while maintaining simplicity.
3Manufacturing precision
If fatty acid distribution is optimized for similarity to dairy fats, then solid fat content and melting profile improve, but formulation complexity increases
Solution Approach 1:
The patent manages formulation complexity by focusing on a limited set of key parameters: four specific fatty acid types with defined concentration ranges, and target solid fat content values at three temperature points (4°C, 20°C, 37°C). This streamlined approach achieves accurate melting profiles without excessive complexity.

AI summary
A fat formulation can include triacylglycerides that can be made of glycerol esterified with straight-chain saturated fatty acids, where a solid fat content as a function of temperature of the triacylglycerides differs from a solid fat content of butterfat by at most 0.1 at any temperature between 0° C. and 40° C. A fat formulation can include triglycerides that include straight-chain, saturated fatty acids selected from a distribution of fatty acids with between 4 and 24 carbon atoms, where the distribution comprises a non-monotonic change in relative fatty acid content between the fatty acids with between 4 and 24 carbon atoms.
