Abstract

In recent years, new technologies and the global food market have revealed a tendency to increase the number of high-quality new products designed to prevent various diseases and strengthen the body's defenses. The possibility of using plant raw materials with antioxidant properties is being studied. The authors have developed a technology for obtaining an extract from a walnut shell. Technological processes and modes of extract production are substantiated. A scheme for obtaining the extract is presented. The extract was obtained on a  emi-automatic Soxlet apparatus. To isolate antioxidant substances, the extraction method is most often used. The antioxidant activity and the amount of extraction yield are related to the solvent used. Most often, methanol, ethyl alcohol, chloroform, water, N-butanol and ethyl acetate are used to extract antioxidant compounds, but organic solvents are used for extraction for food purposes. Ethanol and water were chosen as extraction solvents not only because they lead to higher extraction yields, but also because they are safer and less toxic compared to methanol and other organic solvents.
