Abstract
The invention is a method for making improved citrus aqueous essences by a fractionation process wherein citrus aqueous essence is first passed through a solid adsorbent so that part of the essence compounds exit the adsorbent in a first effluent and part remain on the adsorbent, and then at least part of the first effluent is recycled through the adsorbent to recover a fraction of the remaining compounds and produce a second effluent.
