METHOD OF PURIFYING OXIDISED FATS AND OILS USING A NATURAL NANOSTRUCTURED COMPOSITE THERMALLY MODIFIED ADSORBENT Russian patent published in 2019 - IPC C11B3/00 

FIELD: fat and oil industry.

SUBSTANCE: invention relates to the fat and oil industry. Method of purifying oxidised fats and oils using a natural nanostructured composite thermally modified adsorbent comprises cooling or heating thermally treated fat or oil to temperature of not higher than 50–70 °C, passing it through a column having a filter with a tap, which is put on a thermal jacket and filled with an adsorbent. Adsorbent used is a composition of montmorillonite, magnesium silicate, gaize and dolomite obtained by synthesis and deformation of natural material, wherein the adsorbent is used at ratio of 5 % of the weight of fat or oil.

EFFECT: invention reduces amount of adsorbent used, increases quality of purified product, simplifies cleaning and separation of adsorbent from fat.
