Abstract

This article demonstrates the potential application of clay adsorbents obtained by acid activation of local bentonites from the Krantov deposit. The optimal amount of adsorbent required to reduce the color intensity of safflower oil from 15 to 6 mg/iodine, the acid value from 2.6 to 1.5 mg KOH/g, and the peroxide value from 4.4 to 3.1 mmol active oxygen/kg has been determined. It has been shown that after bleaching with the proposed adsorbent, the oxidative stability of the oil meets GOST standards for 150 days and is inferior to imported analogs.
