Study on the effect of supercritical extracts of mint (Mentha piperita L.) and clove (Syzygium aromaticum L.) on the oxidative stability of soybean oil is presented. Extracts were obtained using supercritical fluid extraction and then added to soybean oil at two different concentrations. The effect of the extracts on the stability of soybean oil during the storage period was studied by determining the peroxide and acid values. Mint extract (M. piperita) was analyzed by HPLC with MS / MS identification. A total of 21 different biologically active components were identified in M. piperita SC-CO2 extracts. The oxidative stability of the soybean oil samples enriched with supercritical extracts of clove and mint was higher than in the control sample (without addition of supercritical extracts). Supercritical extracts can be recommended as a source of natural antioxidants to extend the shelf life of vegetable soybean oil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
