While the unwanted substances are removed from the oil during the refining process or the quantities are reduced to an acceptable level; bioactive compounds (tocopherols, phenolic substances, sterols, squalene, etc.) in the oil are lost qualitatively and quantitatively, conjugation and trans isomerization reactions and process contaminants such as 3-MCPD occur. Intrasystem, innovative, technical solutions need to be developed to reduce the loss of bioactive compounds in the refining stages and/or to prevent the formation of undesirable compounds. For this purpose; refining flows, which can be carried out at a lower temperature, shorter processing time, using less chemicals, are supported by innovative techniques such as ultrasound-assisted refining and accelerating chemical reactions, need to be developed. in this review; the scientific studies on ultrasound assisted degumming, neutralisation and bleaching steps are summarized in detail.tr10.5505/pajes.2019.76094info:eu-repo/semantics/openAccessRefiningDegummingNeutralizationBleachingUltrasound crude vegetable oilArticle26712391244WOS:000597063900009N/A
