Abstract
Official abstract text for this publication.
A method for reducing the content of a saturated hydrocarbon in oils and/or fats. The method includes subjecting raw material oils and/or fats to a short path distillation treatment under a temperature condition of 50° C. or higher and 270° C. or lower. In the short path distillation treatment, a feed rate of the raw material oils and/or fats to a short path distillation apparatus may be 30.0 kg/h·m 2 or less per unit area of an evaporation surface of the short path distillation apparatus. The feed rate may be 5.00 kg/h·m 2 or more and 25.0 kg/h·m 2 or less per unit area of an evaporation surface of the short path distillation apparatus.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for reducing a content of all C20-C35 saturated hydrocarbons in raw material oils and/or fats, to produce refined oils and/or fats, the method comprising subjecting raw material oils and/or fats to a short path distillation treatment at a temperature of 200° C. or higher to reduce the content of all C20-C35 saturated hydrocarbons from the oils and/or fats, wherein, in the short path distillation treatment, a feed rate of the raw material oils and/or fats to a short path distillation apparatus is 8.3 to 25.0 kg/h·m 2 per unit area of an evaporation surface of the short path distillation apparatus, wherein the raw material oils and/or fats are palm-based oils and/or fats, wherein a degree of vacuum in the short path distillation treatment is 0.05 Pa, and wherein the content of all C20-C35 saturated hydrocarbons is reduced to less than 2 mg/kg. 2. The method according to claim 1 , wherein the feed rate is 8.3 kg/h·m 2 per unit area of the evaporation surface of the short path distillation apparatus. 3. The method according to claim 1 , wherein an upper limit of the temperature in the short path distillation treatment is 200° C., and the feed rate of the raw material oils and/or fats to the short path distillation apparatus is 8.3 to 25.0 kg/h·m 2 per unit area of an evaporation surface of the short path distillation apparatus. 4. The method according to claim 1 , wherein an upper limit of the temperature in the short path distillation treatment is 200° C., and the feed rate of the raw material oils and/or fats to the short path distillation apparatus is 8.3 kg/h·m 2 per unit area of an evaporation surface of the short path distillation apparatus. 5. The method according to claim 1 , wherein the short path distillation treatment is performed two times or more.
