In this study, the aroma compounds and anthocyanins were recovered from strawberry by using crosslinked acrylonitrile-co-divinylbenzene (AN/DVB) adsorbent. Suspension polymerization technique was utilized for the synthesis of adsorbent resins with a porous character, and the optimal AN/DVB and diluent/DVB ratios of the adsorbent were determined as 0.5 and 1.5, respectively. After that, packed bed applications were carried out using this adsorbent resin. The adsorption process was accomplished by passing 240 ml strawberry juice through the column, and the desorption process was completed by obtaining the eluate from the column in 20 ml methanol. Aroma compounds analyses were applied to the six samples of the column output and eluate which desorbed from the columns. All experiments were carried out in gas chromatography-mass spectrometry. It was determined from the total peak areas that 90 % of the aroma components of the strawberry juice were isolated by the packed bed column. Total monomeric anthocyanins were determined via the pH differential method, and 279.5 and 256.58 mg Pg-3-glu/kg strawberry were found in the strawberry juice and eluate, respectively. Approximately, 92 +/- 1 % of the total monomeric anthocyanins were isolated from the sample. Finally, the prepared column system was reused six times by regeneration and each use gave a similar performance.
