Resumo: |
The QuEChERS extraction method followed by quantification using HPLC/ UV-FL was evaluated for deoxynivalenol (DON) and zearalenone (ZEA) determination in natural and parboiled rice and their fractions (bran and husk). The comparison between QuEChERS and partition with acetonitrile extraction showed that the first one was better. It presented higher recovery (91% for DON, 105% for ZEA) wih precision ranging from 1.5 to 18.6%. The limits of quantification were 22.2 μg kg-1 for DON and 4.3 μg kg-1 for ZEA. DON and ZEA showed higher levels in endosperm of parboiled rice (8 e 111.7 μg kg-1, respectively) when compared to natural rice. |
