Two different sample preparation methods were used and optimised. The GC-MS method was used for various food matrices like breads, potato crisps, potato crackers, french fries. The UPLC-MS method was used for analysis of coffee. The limit of detection and limit of quantification for acrylamide were 7 µg.kg<sup>-1 </sup>and 20 µg.kg<sup>-1</sup> by GC-MS, 9 µg.kg<sup>-1 </sup>and 30 µg.kg<sup>-1 </sup>by UPLC-MS. For both methods the reproducibility, given as relative standard deviation was < 5% , and the recovery was close to 100 %. </p> <p> </p> <p><strong>doi:10.5219/61</strong></p> <br /><p> </p></div></span>
