Plant-Derived Lipid Compositions with Oleic Acid for Oxidative Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for sustainable and stable sources of long-chain omega-3 polyunsaturated fatty acids (LC-omega-3s) such as docosapentaenoic acid (DPA), docosatetraenoic acid (DTA), eicosatetraenoic acid (ETA), and eicosatrienoic acid (ETrA) due to their health benefits and susceptibility to oxidation, which reduces their shelf life in products.
Innovation Solution
Lipid compositions enriched with DPA, DTA, ETA, or ETrA are sourced from plant sources like Brassica juncea, processed to achieve high purity and stability through methods such as distillation and chromatography, and combined with oleic acid to enhance stability and anti-inflammatory activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the omega-3 content is increased to enhance health benefits, then the nutritional value is improved, but the oxidative stability decreases and shelf life is reduced
Solution Approach 1:
The patent uses nitrogen atmosphere during processing and storage to create an inert environment that prevents oxidation of the polyunsaturated fatty acids. This allows the product to maintain high omega-3 content while protecting it from oxidative degradation, thereby resolving the contradiction between nutritional value and oxidative stability
Solution Approach 2:
The patent introduces oleic acid as an intermediary component that synergizes with the omega-3 fatty acids. Oleic acid acts as a stabilizing agent that enhances the overall stability of the lipid composition while maintaining the beneficial health effects of the polyunsaturated fatty acids
2Adaptability or versatility
If plant sources are used to provide sustainable LC-omega-3s, then sustainability is improved, but the purity and concentration of specific fatty acids may be reduced
Solution Approach 1:
The patent employs molecular distillation to extract and separate specific long-chain omega-3 fatty acids (DPA, DTA, ETA, ETrA) from the complex plant oil matrix. This extraction process concentrates the target fatty acids to high purity levels while removing other components, thereby achieving both sustainability from plant sources and high manufacturing precision
Solution Approach 2:
The patent utilizes controlled temperature and pressure parameters during the distillation process to optimize the separation and concentration of specific fatty acids. By adjusting these physical parameters, the process achieves high purity enrichment of target omega-3s from plant sources, resolving the contradiction between sustainability and purity

AI summary
The present embodiments provide a plant-based lipid composition comprising high concentrations of long-chain omega-3 fatty acids, typically as fatty acid esters, comprising DPA, DTA, ETA, or ETrA, optionally with OA or ALA. These enriched lipid compositions have improved stability, and offer a sustainable source for these long-chain omega-3 fatty acids. In some embodiments, these enriched lipid compositions show enhanced modulation of inflammatory markers, such as inhibition of inflammatory cytokines, and offer nutritional or therapeutic value.
