Ultrasound-assisted dispersive liquid–liquid microextraction combined with high-performance liquid chromatography-fluorescence detection for sensitive determination of biogenic amines in rice wine samples

Determination of biogenic amines in semi-dry and semi-sweet Chinese rice wines from the Shaoxing region

“…Lu et al (2007) determined the levels of five biogenic amines (cadaverine, histamine, tyramine, spermine and spermidine) in 14 samples of four different geographical origins by HPLC-DAD after pre-column dansylation. Huang et al (2009) established a procedure for the determination of biogenic amines by means of ultrasound-assisted dispersive liquideliquid microextraction coupled with HPLC-FLD, yet only three samples were analyzed for three amines.…”

“…The indigenous bacteria, together with the abundant precursor amino acids available during the fermentation, could lead to concern about the accumulation of biogenic amines in Chinese rice wines. However, there are few studies on the identification and quantification of biogenic amines in Chinese rice wines (Huang et al, 2009;Lu et al, 2007). The objective of the present work, which represents a preliminary part of a wider research project aimed at control of biogenic amines in Chinese rice wines, was to determine the biogenic amines content of semi-dry and semi-sweet Chinese rice wines from the Shaoxing region using reversed-phase high-performance liquid chromatography (RP-HPLC) coupled with ultraviolet (UV) detection after pre-column derivatization with benzoyl chloride.…”

Development of an ionic liquid-based ultrasonic-assisted liquid–liquid microextraction method for sensitive determination of biogenic amines: Application to the analysis of octopamine, tyramine and phenethylamine in beer samples

“…The derivatization process of DMQC-OSu and BAs has been studied in detail previously [30]. 100 L of mixed amine in water, 400 L of DMQC-OSu solution (2 mM), 200 L of H 3 BO 3 -Na 2 B 4 O 7 buffer (pH 8.0) and 300 L of double-distilled water were added to a 1.5-mL conical tube and then vigorously mixed.…”

Derivatization strategies for the determination of biogenic amines in wines by chromatographic and electrophoretic techniques

“…Further sample re-extraction in basic medium with organic solvents such as chloroform and diethyl ether has been also applied for analyte preconcentration and cleanup [27]. Alternatively, extracts can be purified by SPE with C 18 or ion-exchange cartridges, liquid-phase microextraction [39] and ultrasound-assisted dispersive liquid-liquid microextraction [41]. The lixiviate/extract purification is of great importance to avoid interferences from amino acids on the derivatization step as they remain unextracted.…”
