  • Publication number: 20120121772
    Abstract: A process for preparing an oil mixture of an T6 PUFA (such as ARA) with T3 PUFA (such as DHA and/or EPA) is described which can he included into edible formulations such as foodstuffs, and in particular infant formulas. A crude T6 PUFA (e.g. ARA)-containing oil is admixed with a crude T3 PUFA (e.g. DHA or EPA)-containing oil to produce a crude oil mixture (or blend). This mixture is then purified before addition to a foodstuff Alternatively, a crude T6 PUFA-containing oil is treated, and a crude T3 PUFA-containing oil is also treated, and the two purified oils are then blended prior to deodorising and then added to a foodstuff. The purifying includes acid and/or alkali treatment, bleaching, deodorization, filtering, polishing or cooling. The purifying removes trace metals, pigments, carbohydrates, proteins, sulphur, sterols, mono- or di-glycerides from the oils which renders them suitable for human consumption.

  • Publication number: 20090105342
    Abstract: Edible formulations, such as polyunsaturated fatty acids (PUFAs) such as pharmaceutical compositions or nutritional supplements, are disclosed comprising arachidonic acid (ARA). They are adapted to deliver from 150 mg to 1 g per day of ARA and may contain other PUFAs, for example docosahexaenoic acid (DHA). The DHA dosage is from 400 to 600 mg per day, and the ratio of ARA:DHA may be from 1:5 to 5:1. Pharmaceutical compositions comprising ARA and DHA at a ratio of ARA:DHA of 1:1 to 1:2 are also disclosed, as are foodstuffs comprising 0.1 to 5% ARA. Such formulations can be used to increase ARA levels in vivo, for example in pregnant women or for people who have diseases or conditions associated with low ARA levels.

In particular, and with respect to inner primary coatings, the oligomer should be selected so that the value m of an uncured radiation-curable inner primary coating composition in the equation ? = K ? ? ? ? ? ? ? ? 1 + ( ? ? ? ? ? ) m ( I ) is advantageously equal to or greater than about 0.90.

  • Patent number: 6846955
    Abstract: The invention relates to a process for racemising an enantiomer-enriched Schiff base of a primary amino acid amide with a strong base that is chemically reactive towards water. The reaction is conducted in an organic solvent. Preferably a metal alkoxide, a metal alkyl, a metal amide, or a metal hydride, in particular a metal alkoxide is applied as the strong base. As the Schiff base preferably N-benzylidene primary amino acid amide is used, with the primary amino acid amide preferably being derived from an aliphatic primary amino acid amide, for example tertiary-leucine amide. As organic solvent use is preferably made of an aromatic hydrocarbon, a cyclic, aliphatic hydrocarbon or a ether, in particular an aromatic hydrocarbon is applied. The invention may also be applied for the racemisation of an enantiomer-enriched primary amino acid amide.

  • Patent number: 6841691
    Abstract: Method for the preparation of an enantiomerically enriched ester, in which a mixture of the enantiomers of the corresponding secondary alcohol is subjected, in the presence of an acyl donor, to an enantioselective conversion in the presence of a racemisation catalyst upon which the ester is formed and an acyl donor residue is obtained, and in which the acyl donor residue is irreversibly removed from the phase in which the enantioselective conversion takes place. Preferably the enantioselective conversion is carried out enzymatically and a transfer hydrogenation catalyst is used as racemisation catalyst. The secondary alcohol can be formed in situ from the corresponding ketone, in the presence of a hydrogen donor. It is also possible to use a mixture of the secondary alcohol and the corresponding ketone as substrate. Preferably the acyl donor is chosen so that the acyl donor residue is converted in situ into another compound and/or the acyl donor residue is removed via distillation under reduced pressure.
