Vegetable Fat Composition for Low Saturated Fatty Acid Bakery Products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for bakery fats with low trans and saturated fatty acid (SAFA) content that maintain desirable organoleptic properties, as simply reducing SAFA content does not necessarily result in an acceptable product for consumers.
Innovation Solution
A vegetable fat composition with specific triglyceride content ratios, including 6-20% SSS, 5-25% SUS, 10-39% SU2, and at least 20% U3, and a weight ratio of SUS/SSU between 0.5 and 2.0, produced by blending interesterified palm olein and palm oil fractions with a liquid oil like canola oil, to achieve low SAFA and trans fatty acid content while maintaining structure and appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the saturated fatty acid (SAFA) content of the fat is lowered to achieve health benefits, then the trans fatty acid content can be reduced, but the organoleptic properties (structure, appearance, mouthfeel) deteriorate
Solution Approach 1:
The patent changes the triglyceride composition parameters by controlling specific ratios of SSS, SUS, SSU, SU2, and U3 triglycerides. This allows lowering SAFA content while maintaining the structural parameters (N10, N20, N30, N35) that govern organoleptic properties, thus resolving the contradiction between health benefits and product quality
Solution Approach 2:
The patent creates a composite fat composition blending multiple triglyceride types with specific characteristics. By combining different triglyceride fractions (SSS, SUS, SSU, SU2, U3) in precise ratios, the composition achieves both low SAFA content and maintained organoleptic properties through synergistic interaction of components
2Object-affected harmful factors
If the saturated fatty acid (SAFA) content is reduced to meet consumer health demands, then the fat becomes healthier, but the structure and appearance of baked products deteriorate
Solution Approach 1:
The patent modifies the fat composition parameters by precisely controlling triglyceride ratios while maintaining solid fat content parameters (N10=10-30, N20=8-20, N30=5-8, N35=2-5) that are critical for product structure and appearance, enabling SAFA reduction without quality loss
Solution Approach 2:
The patent applies different triglyceride compositions to different functional requirements: SSS and SUS for structural stability, SU2 for intermediate properties, and U3 for health benefits. This localized functional assignment within the composite fat allows SAFA reduction while preserving structure
3Object-affected harmful factors
If the triglyceride composition is modified to reduce saturated fatty acids, then health benefits are achieved, but the complexity of achieving correct organoleptic balance increases
Solution Approach 1:
The patent simplifies the complex triglyceride composition problem by establishing specific parameter ranges and ratios (SSS 6-20%, SUS 5-20%, SSU 5-25%, SU2 10-39%, U3 ≥20%) that automatically ensure both health benefits and organoleptic quality, reducing formulation complexity
Solution Approach 2:
The patent introduces solid fat content parameters (N10, N20, N30, N35) as control variables that simplify the formulation process. By targeting specific N values, formulators can achieve desired organoleptic properties without navigating the full complexity of individual triglyceride interactions
