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.
本发明是一种通过分馏工艺制造改良柑橘
水溶液香精的方法,其中柑橘
水溶液香精首先通过固体吸附剂,使香精化合物的一部分以第一流出物的形式流出吸附剂,另一部分留在吸附剂上,然后将第一流出物的至少一部分通过吸附剂循环使用,以回收剩余化合物的一部分并产生第二流出物。
