VEGETABLE AND ANIMAL OILS AND FATS Russian patent published in 2014 - IPC C07C69/18 C11B3/06 C11B3/10 C07J9/00 

FIELD: chemistry.

SUBSTANCE: invention relates to environmentally friendly "green" method of continuous purification of triacylglycerols with application of powder-like, granulated or pressed adsorbent, which is applied either in the process of chemical or in the process of physical purification of food oils and fats, each of which is usually used for purification of triacylglycerols. Method of purification of vegetable and animal oils and fats includes the following stages: a) raw triacylglycerol is processes with application of one or more adsorption columns, containing adsorbent material for removal of one or more admixtures from raw triacylglycerol, with said triacylglycerol continuously flowing through one or more columns; b) regeneration of adsorbent material with acid-containing solvent to remove adsorbed admixtures from adsorbent material is performed; c) and adsorbent material at stage (a) is used, with admixtures including one or more phosphorus compounds, soap, metals, free fatty acids, aromatic compounds, odorous compounds, colouring compounds, chlorophyll and other admixtures, reducing stability of final triacylglycerol.

EFFECT: method improvement.
