  • Publication number: 20090156694
    Abstract: Stable oil containing long-chain polyunsaturated essential fatty acids (LC-PUFAs) in the form of triacylglycerols, in particular arachidonic acid (ARA), dihomogammalinolenic acid (DHGLA), docosahexaenoic acid (DHA) or eicosapentaenoic acid (EPA). Such an oil may be prepared by bringing a carrier oil into contact with a biomass obtained from the culture of a microorganism, in particular a fungus or a microalga containing the acids ARA, DHGLA, DHA or EPA. These oils can be incorporated into the composition of a foodstuff, of a cosmetic or pharmaceutical product.

  • Publication number: 20080254153
    Abstract: The invention pertains to a water dispersible, preferably a powder composition of water extractible bioactive components of exclusively fruit or vegetable or plant origin. These components are obtainable by: a) subjecting a selected fruit or vegetable or plant material to homogenisation in weak alkaline conditions and at moderate temperature; b) separating the liquid extract from the homogenised mass and subsequently bringing it to neutrality; and c) eventually concentrating or drying, preferably by freeze drying, the neutralized liquid extract. The composition can be used as primary composition in the preparation of a food product for oral administration, a food supplement, a pet food product, a pet food supplement, a cosmetic preparation or a pharmaceutical preparation.

  • Publication number: 20060068076
    Abstract: A stable oil containing LC-PUFAs in the form of triacylglycerols, in particular arachidonic acid (ARA), dihomogammalinolenic acid (DHGLA), docosahexaenoic acid (DHA) or eicosapentaenoic acid (EPA), may be prepared by direct pressing of one or more biomasses obtained from the culture of a microorganism, especially of a fungus or of a microalga containing the acids ARA, DHGLA, DHA or EPA leading to a first press oil and by bringing a carrier oil entering into the composition of a foodstuff, a cosmetic or pharmaceutical product, into contact with the biomass cake, followed by pressing leading to a second press oil, and then by combining the pressed oils and refining the mixture under controlled conditions.

  • Patent number: 6395316
    Abstract: A coating composition for frozen desserts is in the form of a water-in-oil emulsion which comprises about 65 to 80% by weight water phase and about 0.5 to 8% by weight of an emulsifier. The coating composition may be used to form a film, a layer, or an inclusion in a frozen dessert product.

  • Patent number: 6297279
    Abstract: A method for preparing a synthetic lipid composition in which the content and the distribution of the fatty acids are similar to those of human milk fat, containing less than 2% by weight of free fatty acids, in which palmitic acid is predominantly at the 2-position of the triacylglycerols and the arachidonic and docosahexaenoic acids are distributed between the 1-, 2- and 3-position and in particular predominantly at the 2-position of the triacylglycerols. The method includes the steps of interesterifying a mixture of specific lipids with a mixture of free fatty acids, followed by removal of excess free fatty acids by partial deacidification utilizing steam distillation under vacuum and then by controlled neutralization of the partially deacidified fat.

  • Patent number: 5962059
    Abstract: An aerated food product useful as a garnish for preparation of composite products, which may include a baked product such as biscuits wherein the food product is positioned between the biscuits. The food product has a crystalline fat structure and is prepared by mixing skimmed milk powder, a sugar and a sugared concentrated milk, mixing a lipid composition with that mixture to obtain a lipid-added mixture containing from 30% to 60% fat and having a dry matter content of from 80% to 90%, wherein the lipid composition has, by weight, at a temperature of 30.degree. C., a solids content of at least 8%, and then while being cooled to an ambient temperature, the lipid-added mixture is kneaded mechanically and injected with an inert gas to obtain the aerated food product.

  • Patent number: 5679809
    Abstract: A composition concentrated in ethyl esters of polyunsaturated fatty acids is prepared by mixing a refined oil rich in polyunsaturated fatty acids with ethanol in the presence of a catalyst to obtain an ethanolyzate containing a glycerol phase and fatty acid ethyl ester phase. The fatty acid ethyl ester phase is separated from the glycerol phase and mixed with urea and ethanol to form a mixture, which is cooled to form a liquid phase containing fatty acid ethyl esters and a solid phase containing insoluble inclusion complexes. The liquid phase is separated from the solid phase to obtain a fraction enriched in ethyl esters of polyunsaturated fatty acids.

  • Patent number: 5041634
    Abstract: Process for the preparation of compounds of the formula HO-Ar-COOH in which Ar is a substituted or unsubstituted aromatic ring system, by oxidizing, by means of oxygen or compounds which donate oxygen, compounds of the formula HO-Ar-R.sub.1 in which R.sub.1 is alkyl having 1 to 5 carbon atoms and Ar is as defined above, or the O-acyl derivatives of these compounds, in an organic solvent at 80.degree. to 130.degree. C. and in the presence of an acylating agent, a cobalt and/or manganese compound and a compound which donates bromide, ions, and subsequently hydrolysing the products in a conventional manner. In the presence of the acylating agent, a selective oxidation of the hydroxyl-substituted aromatic compounds to carboxylated hydroxy compounds, which are obtained in a good state of purity and yield, is obtained without the application of pressure.The compounds obtained in accordance with the process are, for example, valuable intermediates for the preparation of dyes, plastics and pharmaceuticals.
