Lipid Premix for Stabilizing Unsaturated Fatty Acids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Highly unsaturated fatty acids like DHA and EPA are difficult to incorporate into foods due to oxidation issues and complex addition methods, limiting their use in general food products.
Innovation Solution
A premix is created by mixing oils and fats containing DHA or EPA with oils and fats of predetermined melting points to form an oil phase, which is then combined with an aqueous phase to produce an oil-in-water emulsion composition, reducing off-flavors and stabilizing the emulsion for use in food products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If highly unsaturated fatty acids (DHA/EPA) are directly added to food products, then nutritional value is improved, but oxidation occurs causing off-flavors and stability issues
Solution Approach 1:
The patent uses oils and fats with specific melting points (10-42°C) as intermediary carriers to deliver highly unsaturated fatty acids to the food matrix. This intermediary system protects the sensitive fatty acids from direct exposure to oxidation triggers while maintaining their nutritional value, thereby resolving the contradiction between stability and harmful off-flavors.
Solution Approach 2:
The patent changes the physical parameters of the delivery system by selecting oils and fats with specific melting point ranges (10-42°C). This parameter optimization allows the carrier oil to remain stable at room temperature while releasing the active fatty acids under appropriate conditions, thus preventing oxidation-related off-flavors while preserving nutritional benefits.
2Reliability
If highly unsaturated fatty acids are incorporated into food products, then health benefits are improved, but the addition process becomes complex
Solution Approach 1:
The patent merges the highly unsaturated fatty acids with oils and fats having specific melting points to create a unified premix composition. This combination simplifies the addition process to a single step while ensuring reliable delivery of health benefits, eliminating the need for complex multi-step incorporation procedures.
Solution Approach 2:
The patent performs preliminary action by pre-mixing the highly unsaturated fatty acids with the carrier oils and fats before incorporation into the final food product. This advance preparation creates a stable, ready-to-use composition that simplifies the actual food manufacturing process while guaranteeing consistent health benefit delivery.
3Quantity of substance
If highly unsaturated fatty acids are used in general foods, then nutritional value is enhanced, but oxidation resistance deteriorates
Solution Approach 1:
The carrier oils and fats with specific melting points serve as protective intermediaries that physically shield the highly unsaturated fatty acids from oxidation triggers. This intermediary system allows high concentrations of nutritious fatty acids to be present in the food while maintaining oxidation resistance through the protective carrier matrix.

AI summary
The present invention addresses the problem of providing a premix for preparing an emulsion composition, which makes it possible to easily prepare a food containing a highly unsaturated fatty acid such as DHA or EPA, and an emulsion composition using the same. A premix for preparing an emulsion composition, which makes it possible to easily prepare a food containing a highly unsaturated fatty acid such as DHA or EPA, can be obtained by mixing a highly unsaturated fatty acid-containing fat or oil with a specific fat or oil and then mixing the resultant mixture with a preset amount of an aqueous solvent to thereby give an oil-in-water type emulsion. By using this premix, foods or drinks, for example, a drink in which an offensive taste derived from a highly unsaturated fatty acid is reduced can be easily prepared.
