Problem to be solved: to provide a new method for continuously circulating low fat plastic oil medium oil type oil and fat oil composition using the manufacturing line of existing margarine and fat spread in the production of the water-soluble emulsified oil and fat oil composition of low fat plastic oil containing little quantity of oil.In the manufacturing method of a low fat plastic oil medium type oil emulsion oil composition having an oil content of 15 to 50% by weightAn oil type oil emulsion oil composition having a solid fat content of 2.5 to 15% at 20After this low viscosity oil type oil emulsified oil composition was passed through the plate type heat exchangerIt is cooled and converted into a water type emulsified oil and fat composition in an oil production line in the production line to form a water-soluble oil in the form of a water type oil emulsion.Then, the method of circulating and circulating a low-fat plastic oil intermediate oil type oil and fat composition composition through the process of melting some excess products and applying a 0.3 to 2 MPa pressure to the molten oil in oil type emulsified oil and oil composition and rolling again, and passing through an oil type oil emulsion oil composition.No selection【課題】油分を少量しか含まない低脂肪可塑性油中水型乳化油脂組成物の製造に関し、既存のマーガリンやファットスプレッド類の製造ラインを用いた低脂肪可塑性油中水型乳化油脂組成物を連続的に循環製造する新たな方法の提供。【解決手段】油分を１５～５０質量％とする低脂肪可塑性油中水型乳化油脂組成物の製造方法において、２０℃における固体脂含量を２．５～１５％とした水中油型乳化油脂組成物を調製し、この低粘度の水中油型乳化油脂組成物をプレート式熱交換器中に通液させた後、冷却して製造ライン中で油中水型乳化油脂組成物に転相させて製品の可塑性油中水型乳化油脂組成物とする。その後、一部の余剰の製品を融解する工程を経て、溶融した油中水型乳化油脂組成物に０．３～２ＭＰａ圧力を印加して再び転相させ、水中油型乳化油脂組成物を経る、循環可能な、低脂肪可塑性油中水型乳化油脂組成物を連続的に循環製造する方法。【選択図】なし
