Yield of essential oil from varieties of Citrus sinensis (L.) Osbeck

Abstract Residues are generated after the processing of citrus fruits and can be used for essential oil extraction. Thus, objective this work was to evaluate composition, yield, quality proven 30 orange varieties, as an alternative better use its residues. The peels were crushed subjected hydrodistillation in a Clevenger-type. samples submitted Entirely Randomized Design (DIC) results analyzed Analysis Variance, Principal Component Analysis, Hierarchical Cluster Analysis. greatest gains yielded by varieties Valencia IAC (5.57%), Pera DP 06 (4.75%), Hamlin 20 (4.58%), 25 (4.28%). has potential extract up 7.24 kg per ton orange. Limonene represents 93.18 99.61% components, being major compound among all varieties. Some did not describe secondary compounds or more than one. These components highly antioxidant great importance production cosmetics, personal care products, homeopathy, help gastrointestinal diseases, other uses. It is possible conclude that have different oils, even when same drying extraction process, intrinsic characteristics each variety.
