Propionic acid was separated by steam distillation from samples acidified with phosphoric acid and collected into alkaline solution.<BR>An aliquot of the distillate containing from 2.5mg to 10mg of propionic acid was evaporated to dryness. The acid was then liberated through acation exchange resin, Dowex 50 X8-H type, column (1cm×3cm).<BR>One to two microliters of the eluate containing Propionic acid and trans-crotonic acid as an internal standard was injected directly into the gas-chromatographic column (φ-4mm×3m) with Chromosorb 101. The lower determination limit was 0.002ppm.<BR>Recovery of propionic acid added at 1250, 2500 and 5000ppm levels to bread and sponge cake were 96.3-100.6%.
