AI Technical Summary

Problems solved by technology

The market for omega-3 supplements is huge, but the margins on the products are small and the products are cheap to retail
Expensive chromatographic techniques cannot therefore be used to isolate omega-3 acids from crude marine oils, as the cost of such purification would make omega-3s too expensive to sell
Molecular distillation is currently used to purify ethyl esters of EPA and DHA, such as pharmaceuticals in processing, but this cannot be used to purify crude marine oil

preparation example Construction

[0086] Therefore, consider from another aspect, the present invention provides the preparation method that comprises the composition of water-soluble unsaturated fatty acid salt, comprising:

[0087] (I) hydrolyzing a crude oil comprising at least one unsaturated fatty acid derivative, such as oil of natural marine origin (marine oil), and forming an oil phase comprising at least one fatty acid;

[0088] (II) optionally washing the resulting oily phase with an aqueous lotion;

[0089] (III) adding at least one aminoalcohol compound to the product of step (I) or, if step (II) is carried out, to the product of step (II) in the presence of water to combine with said at least one unsaturated the fatty acid forms a water-soluble salt, thereby extracting the salt into the aqueous phase; and

[0090] (IV) Isolating and optionally drying the aqueous phase.

[0091] Thus, in the first stage of the above process, a natural oil (preferably of marine origin) is hydrolyzed to convert the...

Embodiment 1

[0180] Preparation of DHA Salt (5:1) Containing Chitosan

[0181] A solution of chitosan acetate (100 mg; 17 μmol) in deionized water (4 mL) was passed through Column of A-26(OH) resin (1 g). The resin was rinsed with deionized water (10 mL). A solution of (all-cis)-4,7,10,13,16,19-docosahexaenoic acid (28 mg; 85 μmol) in 96% ethanol (0.5 mL) was added to the combined eluates, A cloudy solution was obtained. After lyophilization, 53 mg of a milky white solid was obtained which charred without melting when heated to 350°C. Store the product in the refrigerator.

Embodiment 2

[0183] Preparation of DHA Salt (20:1) Containing Chitosan

[0184]The previous procedure was repeated using chitosan acetate (100 mg; 17 μmol) and (all-cis)-4,7,10,13,16,19-docosahexaenoic acid (112 mg; 340 μmol). Lyophilization afforded 131 mg of solid.

Abstract

A process for the preparation of a water soluble unsaturated fatty acid salt from a crude composition comprising at least one non-water soluble or sparingly water soluble unsaturated fatty acid or salt thereof, said process comprising: adding to said crude composition in the presence of water at least one amino alcohol compound so as to form a water soluble amino alcohol salt of said acid or salt; separating an aqueous phase; and optionally isolating said salt from said aqueous phase.

Description

technical field [0001] The present invention relates to the preparation of water-soluble unsaturated fatty acid salts, such as water-soluble omega-3 fatty acid salts, from crude compositions comprising unsaturated fatty acids, especially fatty acids of natural origin, such as vegetable or animal oils such as marine oils Or the method of water-soluble omega-6 fatty acid salts. The present invention also relates to certain novel water-soluble salts and mixtures thereof which may be prepared by the methods of the present invention. In particular, the present invention relates to a process wherein water-soluble mono- or polyaminoalcohol salts of omega-3 fatty acids are formed and wherein these compounds are used in health-promoting supplements or pharmaceutical formulations. Background technique [0002] Omega-3 and omega-6 fatty acids are essential fatty acids for human health, but they are fatty acids that cannot be produced by the body itself. Therefore, omega-3 fatty acids...
