abstract
One of the main problems of deodorizer distillates is the difficulty in separating free carboxylic fatty acids
(FFA) from the remaining added-value components, such as squalene. A two-step novel strategy for the
valorization of olive oil deodorizer distillate (OODD) is presented, based on the use of choline hydrogen
carbonate and supercritical carbon dioxide (scCO2). In the first step, the FFA present in OODD were neutralized
with choline hydrogen carbonate to form choline carboxylates. The choline carboxylates
obtained are of interest to the cosmetic industry. Due to their ionic character, they are insoluble in scCO2.
Therefore in the second step, the reaction mixture was subjected to extraction with scCO2 at 15 MPa,
313 K and a gas flow rate of 2 ml min1
, yielding an extract with a maximum FFA content of ca. 3%
(w/w). A valorization supply chain of OODD is proposed.
