摘要:

优化固态发酵食醋中9 种有机酸的高效液相色谱定量分析方法。色谱条件:以C18色谱柱进行分离,流动相为NaH2PO4溶液,流速为0.9 mL/min,检测波长为210 nm,可在14 min内完成检测。在优化的色谱条件下,9 种有机酸的检测线性范围较宽,最低检出限为0.02~1.79 mg/L,加标回收率为96.02%~104.55%,相对标准偏差0.46%~3.52%。该方法具有灵敏、准确、稳定等优点,可用于固态发酵食醋中有机酸的测定。

Abstract:

Quantitative determination of 9 organic acids in traditional Chinese vinegars by high performance liquid
chromatography (HPLC) was optimized. The procedure of HPLC analysis was carried out on a C18 column using sodium
dihydrogen phosphate as the mobile phase. The flow rate was 0.9 mL/min and the detection wavelength was 210 nm. The
HPLC analysis was completed within 14 min. The linear ranges for 9 types of organic acids were wide and the limits of
detection were 0.02–1.79 mg/L. The recovery rates were in the range of 96.02%–104.55% with relative standard deviation
(RSD) of 0.46%–3.52%. This method is sensitive, accurate, repeatable and suitable for the determination of organic acids in
traditional Chinese vinegars.

Key words: solid-state fermented vinegar, high performance liquid chromatography, organic acids
