摘要： A vegetable oil physical refining process able to mitigate the occurrence of glycidyl esters (GE) including at least a deodorization step followed by a stripping step, wherein, the deodorization step includes contacting said vegetable oil with steam at a pressure above 5 mbara, during at least 10 minutes at a temperature of at least 230° C., and wherein the stripping step includes stripping the oil resulting from the deodorization step at a pressure below 5 mbara and at a temperature not exceeding 280° C. The process does not compromise the heat bleaching and the full removal of unwanted colours, taste and smell from the physically refined edible oil.

摘要： A method for purifying low-quality glyceridic material usually unfit for use as feed or food includes a thermal treatment of the low-quality glyceridic material and subsequent chemical treatments. Alkali containing compounds, such as soaps, and glycerol, can be added to the low-quality glyceridic prior to its thermal treatment.
