Additional equipment may be required. Or do you know how to improve StudyLib UI? No serious or life-threatening side effects were observed on the haematological and biochemical parameters of mice fed with specific dose of EO of Citrus limettioides, therefore the EO can be recommended as safe fumigant for preservation of food commodities. That gave the enhanced yield and extractability of the Orange peel oil constituents. grapefruit using steam distillation and use the extract to determine the optical rotation of our The distillation of a homogeneous binary mixture produces a vapor to which each component in the mixture contributes a part. However, it is crucial to be precise when moving the oil solution from one beaker to another, since it is more likely for the oil's residue to be left on the sides of the equipment used. [
