METODA UNTUK MEMURNIKAN LEMAK DAN MINYAK YANG BERASAL DARI HEWAN ATAU TUMBUH-TUMBUHAN

摘要

pIn a process for purifying fats or oils of animal or vegetable origin, impurities such as free fatty acids, scents or flavours contained in the fat or oil are extracted with a polyethylene glycol. Appropriate polyethylene glycols have an average molar mass from 200 to 1500 g/mol. The preferred polyethylene glycols are PEG 400 and PEG 600. The disclosed process is also suitable for a continuous application in which the extracting agents used are recovered and returned into the circuit./p [DE19638459A1]
