    摘要: Present invention relates to a process for reducing the content of MOSH and/or MOAH from vegetable liquid oil, wherein the process is comprising the step of subjecting vegetable liquid oil to a short-path evaporation, wherein the short-path evaporation is performed at a pressure of below 1 mbar, at an evaporator temperature in a range of from 200° C. to 300° C., and with a feed rate per unit area of evaporator surface of the shorth-path evaporation equipment in a range of from 30 to 220 kg/h·m2. Present invention further relates to the use of short-path evaporation performed at a pressure below 1 mbar, at an evaporator temperature of from 200 to 300° C., and a feed rate per unit area of evaporator surface of the shorth-path evaporation equipment in a range of from 30 to 220 kg/h·m2, for reducing the content of MOSH and/or MOAH from vegetable liquid oil.

    摘要: A process of preparing a fat composition comprises the steps of: a) providing a fat, preferably from a single natural source, comprising at least 25% by weight of StOSt triglycerides based on the total glycerides present in the fat, wherein St is stearic acid and O is oleic acid; b) fractionating the fat source obtained in step a) to form a stearin fraction comprising at least 60% by weight of StOSt triglycerides based on the total glycerides present in the fat, wherein St is stearic acid and O is oleic acid; and c) blending the fat source obtained in step a) and the stearin fraction obtained in step b) in a weight ratio of from 90:10 to 10:90 to form a fat composition.
