EXTRUSION PROCESS

PROBLEM TO BE SOLVED: To provide a process for production of an extruded matter including an oil-in-water type emulsion drop including at least one kind of lipid soluble compound, at least one kind of emulsifier and water.SOLUTION: The process for production of an extruded matter is provided in which emulsification is performed in an extruder, an emulsifier, water and a lipid soluble compound are added from different introduction ports of the extruder arranged apart each other, the emulsifier is added first, and then water is added, then the lipid soluble compound is added. In the process for production of an extruded matter, at least one kind of lipid soluble compound of 1 to 50 wt.% is used based on total weight of an extruded matter, preferably 5 to 30 wt.%, at least one kind of emulsifier of 5 to 80 wt.% based on total weight of the extruded matter, preferably 15 to 80 wt.%, more preferably 30 to 80 wt.%, and water of 1 to 90 wt.% based on total weight of the extruded matter, preferably 1 to 80 wt.%, more preferably 1 to 60 wt.%, further preferably 1 to 30 wt.%.SELECTED DRAWING: None 【課題】少なくとも１種の脂溶性化合物、少なくとも１種の乳化剤、および水を含む水中油型エマルション滴の製造方法の提供。【解決手段】押出機内で乳化処理が行われ、乳化剤、水及び脂溶性化合物が、互いに離れて配置された押出機の異なる導入口から加えられ、乳化剤を最初に添加し、その後に水を添加し、その後に脂溶性化合物を添加する、方法押出物の全重量に対して１〜５０ｗｔ％、好ましくは５〜３０ｗｔ％の少なくとも１種の脂溶性化合物が使用され、押出物の全重量に対して５〜８０ｗｔ％、好ましくは１５〜８０ｗｔ％、より好ましくは３０〜８０ｗｔ％の少なくとも１種の乳化剤が使用され、押出物の全重量に対して１〜９０ｗｔ％好ましくは１〜８０ｗｔ％、より好ましくは１〜６０ｗｔ％更に好ましくは１〜３０ｗｔ％の水が使用される、方法。【選択図】なし
