      <study_design>Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Crossover, Purpose: Basic scienece, Randomization description: Each subject is identified by a number from 1 to 24. This number is allocated according to their entrance to volunteers' list in the screening day. Then, the following randomization table is used according to the crossover design of the study. All participants randomized into two sequences of Test/Reference and Reference/Test products
