Orange Essential Oil

Student Experiment

What you need:
– EssenEx® 100 Distillation Kit
– 4 – 8 oranges (Oranges to be consumed by students! — peel is used in experiment!)
– Vegetable/Cheese grater – “pyramid type”
– Small kitchen or postal scale (0-1 KG, 1gm resolution)
– Microwave oven (normal Kitchen type)
– Roll of paper towels, access to tap water and a freezer.
– Oven mitts, towels or gloves to handle the EssenEx reactor while warm
– Previously prepared: 3 ice cores for use during class period (Freeze overnight)
– At least 3 vials for orange oil that will be extracted.

The Experiment: (Duration: ~ 45 minutes)
 Does the method of preparation of the orange skin change the amount of orange oil extracted?
 Quantitative analysis, error, natural organic chemistry,
 Experiential / Cognitive learning.

Method:
– Team: 4 students. Individual groups or one full class observation of team.
—-Prepare orange skins for extraction:
 Grate 80 g of the orange colored portion of the skin (but not into the true orange fruit) with one of the four sides of the grater and 40 g from one of the other three sides, making 3 samples of 40 g each.
—- Place the reactor and one mug of water into the microwave.
—- Follow User Manual for the non-plant specific operation. (6 minutes on Hi)

Collection:
– Pour top contents of beaker into the easy separator.
– While the oil is separating, clean out reactor and let two students perform next run.
– Other two students: Rotate the separator axially by rubbing the neck between the palms of your hands. After a few seconds, observe the oil layer.
– Repeat the process if you believe more oil will collect
– Once the oil is separated, measure the column height in millimeters with a ruler.
– Transfer oil to a vial.
– Repeat for the other two samples and develop conclusions based on mm extracted.
