Abstract
The moisture content of green coffee is increased in the presence of a substantially inert gas atmosphere under a positive pressure to at least about 25% by weight based upon the weight of the moisturized beans. After moisturization, the moisturized beans are heated in the presence of a substantially inert gas atmosphere to a temperature sufficient and for a time sufficient for hydrolyzing and pryolyzing the beans while substantially avoiding charring the beans. The treated beans then are dried.
