Experiment 28

Test onion with iodine for starch; with Fehling solution for sugar. In what form is the carbohydrate found in onions ?

The onion is a native of the Himalaya Mountains. It contains an essential, volatile oil which gives it the characteristic odor and flavor; when eaten, this oil is absorbed by the blood and brought to the lungs, so the odor will remain for some time on the breath. The onion is considered a wholesome, if not a highly nutritious vegetable and is of value because of its stimulating action upon the digestive tract.
