  • Patent number: 8632832
    Abstract: The present disclosure describes a method for the continuous dissolution of e.g. crystalline astaxanthin or canthaxanthin suspension in oil, by applying heat for a predetermined period using an in-line or optionally batch wise-process, followed by cooling the heated solution with an oil phase or heat exchanger. The resulting oil solution may be used as such or added directly to feed components which are turned into feed compositions by extrusion, compaction or granulation. Alternatively the oil solution is spray coated or directly loaded to extruded or compacted pellets and granulates. The disclosure avoids using formulated carotenoids prepared by known multi-step production methods requiring solvents, solvent removal, cooling and emulsification with an aqueous phase or precipitation and recovery steps.

  • Publication number: 20110244028
    Abstract: The invention describes a method of preparing lipid compositions by associating pH sensitive compounds which maybe weak acids, bases or amphoteric compounds with at least one ionisable or pH sensitive group and low water solubility into preformed and standardised lipid particles by pH manipulation. Drug association is carried out in situ by changing the pH of the aqueous medium to pH 6-8 wherein the compound spontaneously partitions into the lipid particles. Drug association may also be carried out by exploiting pH changes in the GI tract. The lipophilic compound is solubilised by the lipid particles and may be used as such for in-vitro and pharmacokinetic assessments or processed for oral, parenteral or topical therapy.

  • Publication number: 20060286169
    Abstract: There is described dry compositions comprising lipophilic compounds associated with low viscosity grades of water insoluble polymer and optionally hydrophilic agent/s associated either as monomolecular or amorphous complexes. There is also described a method of preparing said lipophilic polymer complexes from a solution or homogeneous dispersion employing either water miscible or immiscible organic solvents. The lipophilic polymer complex is precipitated from the solution comprising a water miscible solvent by dilution with water, separating out the precipitated complex, washing, drying and conversion to oral and topical dosage forms. The lipophilic polymer complex may also be prepared by solvent removal involving spray drying or vacuum drying under elevated temperatures using either water miscible or water immiscible solvents. The compositions are characterised by improved dissolution and solubility of the associated compound in aqueous medium.

  • Publication number: 20060233846
    Abstract: The invention describes homogeneous microdispersions comprising at least one hydrogenated or partially hydrogenated membrane lipid with or without enzyme hydrolysis, dispersed in substantially non aqueous, non volatile hydrophilic medium with boiling point above 40° C. More preferably the compositions comprise a mixture of hydrogenated monoacyl and hydrogenated diacyl-lipids and at least one oil. The phospholipid mixture is obtained by controlled enzyme hydrolysis of lecithin or a specific phospholipid, followed by hydrogenation. The compositions have improved rheology, physical and chemical properties, functionality and industrial applicability. The microdispersions are used as such in all types of applications and as functional components with active compounds in products, particularly for improving skin function and facilitating skin repair due to UV damage and aging, in cosmetics and other topical products.

  • Publication number: 20060128665
    Abstract: There is described marine phospholipids (MPL) compositions suitable for human, aquaculture applications comprising a dry composition comprising nutritional components selected from the group consisting of marine phospholipids, marine proteins and amino acid blends obtainable by fluid extraction of a dried marine raw material. The compositions have low amounts of neutral lipids and particularly low amounts of cholesterol and cholesterol esters. They may be used either as such in powder form and for preparing purified MPL compositions by ethanol extraction. Both forms may be used as nutritional supplements, ingredients for functional foods and to optimise the delivery and containment of nutritional components in multicomponent fish feed compositions. There is further described a blend of the purified, ethanol extracted MPL compositions mixed with marine, vegetable, microbial or MCT oils to form liquid preparations for hard or soft gel encapsulation.
