Title
(DE) ENTFERNUNG VON UNERWÜNSCHTEN PROPANOLKOMPONENTEN
(EN) REMOVAL OF UNWANTED PROPANOL COMPONENTS
(FR) ÉLIMINATION DES COMPOSANTS DE PROPANOL INDÉSIRABLES
Abstract
(EN) 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.
(FR) La présente invention concerne l'utilisation d'une évaporation à chemin court pour réduire, à partir d'huiles triglycérides désodorisées, la teneur en composants propanols choisis parmi les chloropropanols, les esters d'acides gras de chloropropanols, les époxypropanols, les esters d'acides gras des époxypropanols et les combinaisons d'au moins deux d'entre eux. Elle concerne en outre l'utilisation d'une évaporation à chemin court, dans laquelle on a en outre une réduction de la teneur en composants acylglycérols, et dans laquelle ces composants acylglycérols sont sélectionnés parmi les diacyl-glycérols, les triglycérides ayant une masse moléculaire comprise dans la plage inférieure à 730, et les mélanges d'au moins deux d'entre eux.
