This review examined the composition and antimicrobial activities of citrus peel essential oils. Citrus peels are the waste product of fruit processing industry rich in essential oil (EO) with many phytochemical compounds of excellent antimicrobial properties against many bacteria and fungi. The citrus peel EOs has been widely used in pharmaceuticals, foods and other industries as preservatives, and its generally regarded as safe (GRAS). The extract can be obtained through extraction different techniques such steam and hydro-distillation. The components of the EOs are important and their quality depends on the qualitative and quantitative characteristic of the oils. Equipment such as gas chromatography (GC)-flame ionization detector (FID) and GC-MS are widely used for their analysis. The growing concern on the serious microbial spoilage and the interest in shifting from synthetic to natural antimicrobial agents leads to research and screening of plant and other vegetable sources to identify new compounds for the manufacturing and industrial uses. Although the antimicrobial properties of EOs have been reviewed extensively, the antimicrobial properties of citrus peels oil have not been extensively discussed. The hydro-distillation methods appeared to be more widely used by many researchers, perhaps due to its efficiency, inexpensive and yield of excellent quality EOs.
