Abstract
Official abstract text for this publication.
The present invention relates to the use of short-path evaporation for reducing from deodorized triglyceride oils the content of propanol components selected from chloropropanols, chloropropanol fatty acid esters, epoxypropanols, epoxypropanol fatty acid esters, and combinations of two or more thereof. It further relates to the use of short-path evaporation wherein further the content of acyl glycerol components is reduced and these acyl glycerol components are selected from diacyl-glycerols, triglycerides with molecular weight in the range below 730 and mixtures of two or more thereof.
First claim
Opening claim text (preview).
1 . A method for reducing the content of propanol components in a deodorized triglyceride oil comprising: performing short path evaporation on a deodorized triglyceride oil at a pressure below 1 mbar, wherein the content of propanol components in the deodorized triglyceride oil is reduced and the propanol components are selected from the group consisting of chloropropanol fatty acid esters, epoxypropanol fatty acid esters, and combinations thereof. 2 . The method according to claim 1 , wherein the content of epoxypropanol fatty acid esters is reduced to a content below 500 ppb. 3 . The method according to claim 1 , wherein the content of chloropropanol fatty acid esters is reduced to a content below 500 ppb. 4 . The method according to claim 1 , wherein the content of acyl glycerol components in the deodorized triglyceride oil is reduced and the acyl glycerol components are selected from the group consisting of mono-acyl glycerides, diacyl-glycerides, and/or triglycerides with molecular weight in the range below 730, and mixtures of two or more thereof. 5 . The method according to claim 1 , wherein the content of the acyl glycerol components selected from mono-acyl glycerides, diacyl-glycerides, and/or triglycerides with molecular weight in the range below 730, and mixtures of two or more thereof, is reduced by at least 60%. 6 . The method according to claim 1 , wherein the short-path evaporation is performed at a temperature of from 150 to 210° C. to reduce the content of epoxypropanol fatty acid esters in a refined, bleached, deodorized palm oil. 7 . The method according to claim 1 , wherein the short-path evaporation is performed at a temperature of from 180 to 270° C. to reduce the content of chloropropanol fatty acid esters in a refined, bleached, deodorized palm oil. 8 . The method according to claim 1 , wherein the short-path evaporation is performed at a temperature of from 150 to 200° C. to reduce the content of epoxypropanol fatty acid esters in a refined, bleached, deodorized coconut oil. 9 . The method according to claim 1 , wherein the short-path evaporation is performed at a temperature of from 150 to 240° C. to reduce the content of chloropropanol fatty acid esters in a refined, bleached, deodorized coconut oil. 10 . A method according to claim 1 , wherein the method comprises the following steps: a. refining of triglyceride oil, b. bleaching of refined triglyceride oil c. deodorization of refined bleached oil, and d. short path evaporation of refined, bleached and deodorized oil at a pressure below 1 mbar. 11 - 12 .
