IMMOBILIZED ENZYME AND ITS USE FOR THE PROCESSING OF TRIGLYCERIDE OILS

摘要

Process for the immobilization of an enzyme, characterized by the steps comprising: a) selecting an amphiphilic enzyme for immobilization, b) preparing an emulsion comprising a continuous hydrophobic phase and a dispersed aqueous phase in which are dissolved the enzyme and material suitable to act as carrier for the enzyme when the next step is carried out, c) removing water from the aqueous phase until this phase turns into solid enzyme coated particles. A preferred aqueous phase is prepared with a crude lipase fermentation liquid from which the biomass has been removed and which still contains fermentation residues suitable to act as carrier. Processes using the immobilized enzyme comprise interesterification, deacidification and degumming of triglyceride oils and show a very low enzyme consumption. Besides lipases suitable amphiphilic enzymes are phospholipases.
