Abstract: The present invention provides a method for reducing the level of free fatty acids in biodiesel/fatty acid alkyl esters. The method comprises providing a composition comprising fatty acid alkyl esters, free fatty acids and/or a fatty acid feedstock, reacting said free fatty acids and/or said fatty acid feedstock with alcohol in the presence of one or more liquid lipolytic enzymes to produce fatty acid alkyl esters; and/or reacting the free fatty acids and/or said fatty acid feedstock with alcohol in the presence of one or more non-enzymatic catalysts to produce fatty acid alkyl esters.

Abstract: The invention provides enzyme particles comprising an immobilized lipolytic enzyme, a hydrophobic polymer, an organic filter aid, and a water-soluble polyol selected from carbohydrates and sugar alcohols. The particles are suitable for enzymatic interesterification of triglycerides, and subsequent separation of the enzyme and triglycerides by filtration.

Abstract: The present invention provides a lipase powder composition which comprises a filter aid(s) and a product obtained by pulverizing a Thermomyces sp.-derived lipase immobilized to a silica carrier(s) into the average particle diameter of 1 ?m or more and less than 300 ?m. This lipase powder composition improves the lipase activity and operability and, therefore, can be suitably used in the methods for exchanging esters of fats and oils and for esterification.

Abstract: The present invention relates to a process for enzymatic lipase interesterification of oils containing a chelating agent by sequential or simultaneous treatment with a base.

Abstract: The present invention relates to a method for treatment of oil with a lipolytic enzyme which comprises contacting of the oil with particles of base-containing porous amorphous silica.

Abstract: The invention relates to the utilization of fatty materials with substantial free fatty acid content in the production of biodiesel by the use of microbial enzymes that are effective in a solvent-free process for the production of esters of fatty acids and C1-C3 alkyl alcohols.

Abstract: The present invention relates to a method for producing fatty acid alkyl esters, such as fatty acid methyl esters (FAME) and fatty acid ethyl esters with a low level of impurities such as phospholipids. The method of the invention is simplified by combining two process steps into one single process step and is therefore economically cheaper. The method includes mixing water, alcohol, triglyceride and/or free fatty acids a lipolytic enzyme and a phospholipase. Subsequently the aqueous phase, which contains glycerine, residual enzyme and most of the hydrolyzed phospholipids, is separated from the non-aqueous phase, whereby the content of phospholipids in the non-aqueous phase is reduced.

Abstract: A process for producing a glyceride product which is enriched in monounsaturated fatty acids relative to the starting glyceride comprising the steps: (a) alcoholysis of triglycerides employing lipolytic enzymes selective for saturated fatty acids and/or lipolytic enzymes selective for the 1-position, the 3-position or both positions in a glyceride; and (b) separation of fraction A which is enriched in saturated fatty acid esters from fraction B which is enriched in monounsaturated glycerides.
