  • Publication number: 20150025260
    Abstract: A process for the isolation of desired compound(s) from a microbial biomass is disclosed, wherein the microbial biomass (which, if necessary, is pretreated to give a dry matter content of from 25 to 80%) is granulated (e.g. by extrusion) and then dried to a dry matter content of at least 80%. The granulation of the biomass to granules significantly eases subsequent drying of the biomass (which can be stored as dried granules) and gives higher yields on extraction of the compound(s).

  • Publication number: 20140100380
    Abstract: The present invention relates to a process for obtaining lipid from a composition comprising cells and water, said process comprising contacting the composition with a desiccant, and recovering the lipid from the cells. The invention also relates to a lipid obtainable by this process. The process according to then invention enables lipid of high quality to be obtained with a high yield, and does not require a heating step.

  • Publication number: 20130309721
    Abstract: The present invention describes a mannoprotein solution which has a turbidity, when measured by nephelometry at a concentration of 200 g/l of mannoprotein and at a pH in the range of pH 4 to pH 8 lower than 70 NTU, preferably lower than 60 NTU, more preferably lower than 50 NTU, most preferably lower than 40 NTU. This solution can be advantageously used in the stabilisation of wine against tartrate salt precipitation because it is very clear and can be added directly to the wine without causing any turbidity.

  • 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: 20100119671
    Abstract: The present invention describes a composition suitable for use in wine comprising at least 2.5% of a peptide mixture based on dry weight characterized in that the peptides have a molecular weight between 3 kDa and 10 kDa. The composition or a solution thereof can be advantageously used to stabilise wine, in particular to prevent or retard the formation of tartrate salts in the wine.

  • Patent number: 7431952
    Abstract: The extraction of a microbial or single cell oil, for example comprising one or more polyunsaturated fatty acids (PUFAs), directly from microbial cells is disclosed which avoids the need for solvents. After fermentation, the microbial cells are pasteurised, washed and the cell walls lysed or disrupted by a mechanical (e.g. homogenisation), physical (boiling or drying), chemical (solvents) or enzymatic (cell wall degrading enzymes) technique. The oil (containing the PUFA) is then separated from the resulting cell wall debris. This is achieved by centrifugation, which results in an oily phase (top layer) that contains the oil which that can be separated from an aqueous phase (containing the cell wall debris). The oil can then be extracted and if necessary the PUFA can be purified or isolated from the oil.

  • Patent number: 7045160
    Abstract: The preparation of a proteinaceous substance suitable for use in a foodstuff is described which comprises fungal fells of the order Mucorales. The cells are grown in a fermentor vessel in a liquid which is mixed during fermentation, after which the RNA content of the fungal cells is reduced to below 4% the fungal cells processed into an edible substance. This substance is then mechanically texturized into edible textured product for inclusion into foodstuffs, for example in the form of chunks as a meat substitute.
