Omega-3 fatty acids > for food and dietary supplements

Fatty acids are classified in three different groups: Saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids. The polyunsaturated fatty acids (PUFA) could be separated in Omega-6 fatty acids and Omega-3 fatty acids. The Omega-3 fatty acids have the first double bond at the carbon number 3 counting from the methyl end, the same for the Omega-6 fatty acids from the 6 carbon counting from the methyl end.
Saturated and monounsaturated fatty acids can be synthesized by the human body. In contrast Omega-3 fatty acids can nearly not be synthesized in the human body and must come from the diet trough foods and supplements. In the western diet people have normally a very low intake of Omega-3 fatty acids. The ratio between the omega-6 fatty acids and the omega-3 fatty acids should ideally be 2:1. In the modern diet this ratio has increased to more and more omega-6 fatty acids.
Sources for omega-3 fatty acids are plant oils and marine oils. Soybean, rapeseed and walnut oil have a high content of ?-linolenic acid (ALA). The fatty acid ALA is an essential nutrient and humans are not able to synthetize it. ALA can be transformed to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). But the conversion is very low, therefore the fatty acids EPA and DHA can be reconsidered as essential. The only sources for EPA and DHA are marine oils.
Omega-3 fatty acids are important structural components of the phospholipid cell membranes of the tissues. The composition of the phospholipids influences the characteristics of the cell membrane as fluidity and permeability to other molecules.
DHA is one of the major PUFA in the brain, nervous tissue and retina. It seems that DHA is essential for the visual process in the retina and for proper brain functioning.
EPA is a precursor for eicosanoids. These are substances which play an important role in processes like the blood pressure, renal function, blood coagulation, inflammatory and immunological reactions. Eicosanoids derived out of EPA have anti-inflammatory, anti-thrombotic, vasodilatory and triglyceride lowering properties. Due to these effects a high consumption of Omega-3 fatty acids is related to a lower risk for a cardiovascular diseases.

Deficiency symptoms

The risk of developing n-3 fatty acid deficiency is higher in babies and children than in adults. Visible signs of deficiency have only been observed in seriously ill patients on a special fat-free diet for several months. The patients were seen to develop extensive inflammation of the skin, ulcers, reduced visual acuity, disturbed superficial and depth sensibility, muscular weakness, and trembling. The main risk groups for essential fatty acid deficiency are premature babies and babies who are not breast-fed.

Brands

Omevital®, Crystalpure®, Maxomega®, PronovaPure®, Omega 3 powder

Properties

BTC’s Omega-3 fatty acids from BASF are available in various different grades as oils but also as powder forms.
Omega-3 oils are insoluble in water, sparingly soluble in ethanol, miscible with organic solvents, vegetable oils and fats.
Stability: Omega-3 fatty acids are sensitive against oxygen, heat and light. Therefore the products should be stored in the original, tightly sealed and lightproof packaging.
Shelf life and recommended temperature of storage are varying within the different grades.

Applications

Omega-3 Powders
The Omega-3 Powders are produced with the unique encapsulation technology of BASF. These products are suitable for the fortification of basic food products, especially dairy based powder products. Omega-3 powders are particularly suitable for the fortification of baby food and maternal nutrition products.
The matrix is composed of sucrose, caseinate and corn starch. Due to the microencapsulated form, the products have an excellent stability; no refrigerated storage is needed and good organoleptic properties can be noticed. The dry powder leads to an easy homogenization with other powders; source of omega-2 fatty acids in BASF powder are marine oils.

Omega-3 Oils
The Omega-3 Oils provided by BTC are all deriving from fish oil. Fish oil is the only natural source which contains polyunsaturated long chain fatty acids as the EPA (Eicosapentaenoic acid) and the DHA (Docosahexaenoid acid).
The Omevital® product range is perfectly suitable for all applications in the dietary supplement industry - the Omevital® Ultra range has an extremely low level of contaminants, whereas the Omevital® Gold range is representing specially deodorized products for food and chewable applications. Omevital® Ethylester concentrates are suitable for soft gelatine capsules.
With the PronovaPure® range BTC offers products in a pharmaceutical quality for the dietary supplement market. The products are manufactured after the highest pharmaceutical standards. The patented purification process is unique and results to superior oxidation parameters. The products are available as ethyl ester or in triglyceride form for dietary supplement applciations.
The Crystalpure® products are non-chemically modified specialty TG fish oils for high value applications. Unlike to all other Omega-3 concentrates, Crystalpure® is using differences in freezing points to separate the different fatty acid molecules. The result is 100% natural oil with higher lever of omega-3. The main application for Crystalpure® products is taking place in the clinical nutrition and infant nutrition segment. The products are designed for applications requiring pure natural oil.
The products of the Maxomega® range are produced with an advanced chromatographic separation method that allows the concentration of any specific fatty acid up to 99% purity. Maxomega® products are high-end concentrated omega-3 fatty acids. They are produced by a proprietary HPLC (High Performance Liquid Chromatography) technology. This technology provides options to produce specific EPA/DHA ratios. Maxomega® products are available as Ethyl Esters. The Triglyceride form is under development.
Target companies are such, who want to differentiate their portfolio from competition or companies with a specific health concept/philosophy.
