In addition, 2 extra compounds, cyclic PA-BD4-AA3 and cyclic PA2-BD3-AA, were only identified in juice samples after FPSE extraction. Besides, in order to quantify the compounds identified, an isolation procedure for PLA oligomers was carried out. Two oligomers were isolated cyclic (LA)6 and linear HO-(LA)4-H, both with a purity higher than 90% (LA lactic acid). The highest concentration value was found for the cyclic oligomer [AA-BD]2, that showed 22.63 μg g-1 in 3% acetic acid and 19.64 μg g-1 in juice. The concentration of the to
