The invention relates to a method for the enzymatic production of emulsifiers containing mono- and diacylglycerides. In a first step a), a mixture of a phospholipid component and a triacylglyceride component is prepared, then in step b) a quantity of an aqueous solution containing a (phospho)lipase is added to the mixture obtained, to produce a water content of the mixture of between 3 and 15 wt. %. In a subsequent step c), the mixture obtained in the previous step is reacted at a temperature ranging between 20° and 80° C. over a period of at least two hours and said mixture is then dried. Crude soy lecithin and vegetable and/or animal oils, which are reacted together with a mixture of lipase and/or phospholipase as the enzymatic component, are particularly suitable as components. Said method, which does not require the usual organic solvents, polyols or ionic additives and which only requires a small quantity of water, permits the production of emulsifiers, whose composition of lysophospholipids and mono-/diacylglycerides can be adjusted in a targeted manner. Said emulsifiers, which can also be obtained in liquid form, are used in the foodstuff and cosmetic industries. |
