Preparation of Conjugated Linoleic Acid by Ultrasound-assisted Nanonickel Catalyst Isomerization of Sunflower Oil

Abstract

lating metabolism and lowering cholesterol levels 5 . The study found that by adding sunflower oil to goat feed, the content of conjugated linoleic acid in the dairy products produced by the experimental goats was significantly higher than that of the feed without sunflower oil, and improved the quality of goat milk 6 .The current methods for preparing conjugated linoleic acid are roughly divided into two categories: biological methods and chemical methods. Biological methods have a long reaction time, low yield, strict environmental requirements, and difficult product purification 7 . The chemical method mainly uses strong alkali, which has a fast reaction and high yield, but the washing of strong alkali severely pollutes the environment, and needs to be reacted at high temperature, which requires high energy consumption 8 . Some transition elements such as ruthenium, germanium,

Comparison of reactive sites of different conjugated linoleic acid molecules by quantum chemical calculations

“…[ 7 ] Previous studies of CLA mainly focused on the conversion process, content in food, isomerization method, and nutritional properties. [ 8,9 ] In contrast, the study of the reactive sites of CLA has not been addressed; the prediction of the reactive sites is valuable.…”
