PURPOSE: To simultaneously obtain various kinds of flavor imparting compsns. having high quality by heating fat or oil of a liquid pool type to a prescribed temp. with a batch type device mounted with a gas inflow port and discharge port and elements for collecting distilled and evaporated matter in the presence of oxygen. CONSTITUTION: The fat or oil 22 (e.g.; beef fat, rapeseed oil) of the liquid pool type or a mixture composed of >=2 kinds of the fats, oils, etc., is housed into a cylinder 10 having a stirring machine 11, the air inflow port 12, the air discharge port 13, a jacket 14 for heating, etc. While air is introduced into the cylinder from the air inflow port 12 and while the mixture is kept stirred by the stirring machine 11, the mixture is heated to 300 to 475 deg.C and the distilled and evaporated matter is introduced through the air discharge port 13 into the cooling trap 15 and is fractionated with lapse of time. The matter is then recovered from a tap 16, by which various kinds of the flavor imparting agents are obtd. The evaporated matter passing the cooling trap 15 is recovered by a cooling trap 18. |
