This work describes a simple, rapid, and reliable HPLC method for the determination
of organic acids in fermented shrimp waste. Lactic, acetic and citric acids were quantified
by HPLC with UV detection, on a 250´4.6 mm Extrasil ODS 5-mm column, mobile phase
was ultrapure water adjusted with metaphosphoric acid to pH=2.1, flow rate 0.6 mL/min,
column temperature 30 °C, and detection wavelength 210 nm. Under these conditions, the
recovery (97.5 %) and the method repeatability (RSD=6.2 %) for lactic acid were of satisfying
quality. Organic acids can preserve the quality and nutritive value of fermented
shrimp waste.
