Biology of Bitterness

Passage preview

There is a reason why grapefruit juice is served in little glasses: most people don’t want to drink more than a few ounces at a time. Naringin, a natural chemical compound found in grapefruit, tastes bitter. Some people like that bitterness in small doses and believe it enhances the general flavor, but others would rather avoid it altogether. So, juice packagers often select grapefruit with low naringin, though the compound has antioxidant properties that some nutritionists contend may help prevent cancer and arteriosclerosis.
