Abstract

The possibility of using various types of natural powder and acid-modified clay materials as sorbents for the purification of unrefined rapeseed oil from coloring matter was studied. It was demonstrated that the content of carotenoids and pigments of the chlorophyll group in low erucic acid content rapeseed oil treated with a sorbent does not depend on the type of clay. It was found that the pulverization treatment of the surface of clays with solutions of succinic and oxalic acids in comparison with the action of natural sorbents leads to an insignificant (6–14%) decrease in the degree of extraction of dyes from rapeseed oil.

天然粘土在色浆中纯化菜籽油中的应用

摘要

研究了使用各种类型的天然粉末和酸改性粘土材料作为吸附剂从色料中纯化未精制菜籽油的可能性。已经证明，用吸附剂处理的低芥酸含量的菜籽油中叶绿素基团的类胡萝卜素和色素的含量与粘土的种类无关。研究发现，与天然吸附剂的作用相比，用琥珀酸和草酸溶液对粘土的表面进行粉化处理可导致菜籽油中染料的提取率下降不明显（6–14％）。
