Abstract: Oil is an important source of energy for the body, and its quality characteristics, nutritional value and safety have attracted the increasing attention of consumers. With the development of omics technology, genomics, transcriptome, proteomics and metabonomics have been widely applied to the field of oil science. Oilomics is a comprehensive subject that integrates multiple omics technologies to evaluate the physical and chemical properties, nutrition and safety of oil in the whole chain from plantation, processing, storage and consumption. Compared with traditional lipidomics, oilomics offers a more extensive and comprehensive research scope, which has gradually become an important branch of foodomics. This paper introduces the reader to the definition of oilomics and the methods used in this area and its application in research on oil nutrition and safety. We believe that oilomics can provide a more advanced strategy for research in oil science.

Key words: oilomics; physical and chemical properties; process; nutrition; safety
