Food-Grade Omega-3 Fatty Acids

Odorless & High Purity & Stable Supply

Why Omega-3 Matters in Modern Nutrition

With improved living standards, people are paying increasing attention to their health, driving the continuous development of modern nutritional science. Omega-3 fatty acids are essential nutrients for the human body, which cannot be synthesized by the body and must be obtained from external foods.

Omega-3 fatty acids include ALA (Alpha-Linolenic Acid), EPA (Eicosapentaenoic Acid), and DHA (Docosahexaenoic Acid). The core functions of Omega-3 fatty acids are protecting the heart, supporting brain development, protecting vision, and anti-inflammatory effects.

With the increasing demand for daily nutrition and the continuous innovation of functional foods, EPA and DHA are becoming important components of modern nutritional solutions.

Polifar is a supplier of Omega-3 fatty acids. Utilizing advanced and innovative processes, they can provide high-quality fish oil with a purity of over 60%.

Oxidative Stability

Omega-3 is a polyunsaturated fatty acid, and oxidation control is a crucial issue in its food applications.

When Omega-3 fatty acids are improperly stored or exposed to excessive oxygen, light, and high heat, they will oxidize, deteriorate, and become inactive. Polifar's food-grade Omega-3 fatty acid raw materials are packaged to prevent oxygen exposure and stored away from light and heat, with strict quality control for each batch.
No Fishy Odor

A suitable omega-3 composition should provide nutritional value without compromising the sensory experience of the finished food product.

Most EPA and DHA components of omega-3 fatty acids are extracted from deep-sea fish, resulting in a strong fishy odor. Some fish oil products on the market negatively impact the user experience. Polifar's EPA and DHA are thoroughly purified using advanced deodorization technology, reducing odor from the source of the omega-3 fatty acid raw materials.
Formulation Compatibility

Different food systems have different requirements for Omega-3. Modern artificially fortified foods that require added Omega-3 fatty acids include: fish oil, dairy products, cereal baked goods, eggs, seasonings, pasta, and some powdered foods.

The addition of EPA and DHA to dairy products requires stable emulsification properties. The addition of food-grade Omega-3 fatty acids to cereal baked goods, eggs, seasonings, and pasta requires good processing resistance and dispersibility. Powdered foods, including some milk powders and baby food products, need to maintain the flowability and stability of the powder.
Fish Oil Production Process

The generally accepted methods for extracting fish oil in the market include: molecular distillation, urea encapsulation, AgNO3 silver nitrate process, supercritical fluid extraction, distillation, supercritical fluid chromatography, and preparative chromatography. Some of these processes are safe for production but cannot extract high-purity fish oil. Some can extract high-purity fish oil, but their efficiency is insufficient. Some can efficiently produce high-purity fish oil but are not suitable for food-grade fish oil production.

Polifar's production process differs from all of the above methods. Its unique and innovative production process gives its fish oil raw materials a unique advantage over many competitors. It meets both food-grade safety requirements and the requirements for high-purity absorption.
Climate Issues

Frequent extreme weather events globally, with 2026 being a typical El Niño year, have led to a reduction in fish supplies. Fish oil producers are facing raw material shortages, resulting in a market scarcity and excessively high prices for Omega-3 fatty acids. Even at these high prices, securing supplies remains difficult.

Polifar's high-purity refined fish oil products elevate purity to a new level, with a Gardner color index below 2, approaching colorless. Safe and clean production processes result in low oligomer content and a pure odor. Customized products are available, selecting the most suitable Omega-3 raw materials based on the specific production application. Ample supply and fast delivery are guaranteed.

Common Omega-3 Foods

Foods High in Omega-3：Omega-3 comes from two main sources, animal and plant.

Animal and marine sources primarily provide EPA and DHA, which the human body can directly and efficiently absorb. Examples include deep-sea fish such as salmon, mackerel, saury, sardines, and herring. Fish roe, shrimp, and shellfish also contain some Omega-3.

Plant and algal sources mainly provide alpha-linolenic acid (ALA), which needs to be partially converted into EPA and DHA in the body. Microalgae/algal oil is a vegan source that can provide both DHA and EPA. Chia seeds, flaxseed and flaxseed oil, perilla seed oil, hemp seeds, and walnuts are rich in ALA, while cruciferous vegetables such as Brussels sprouts and edamame contain only trace amounts of ALA.

FAQ

1. What Is The Difference Between EPA and DHA?

EPA primarily supports cardiovascular health and inflammation regulation; DHA is an important component of the brain and retina, and is more important for brain and vision health.
2. How To Choose The Appropriate EPA:DHA Ratio?

Choose according to application needs. Cardiovascular health usually favors higher EPA; brain and infant nutrition focus more on DHA, and can also be rationally combined according to product formulation.
3. Is Fish Oil Omega-3?

Fish oil is not a single component, but a fat rich in omega-3 fatty acids, mainly including EPA and DHA.
4. Are Omega-3 Fatty Acids Saturated or Unsaturated Fats?

Omega-3 fatty acids are polyunsaturated fatty acids (unsaturated fats). The human body cannot produce them on its own and must obtain them from foods such as salmon and flaxseed, which are very good for heart and brain health.
5. Can Polifar Provide A Certificate of Analysis (COA) and Product Specifications?

Yes. Polifar can provide corresponding Certificates of Analysis (COA) and product specifications based on the product; specific information can be confirmed according to customer requirements.
