Bread samples enzymatically digested for 1 hr were analyzed by high performance liquid chromatography in 10 min for sodium 6-0-palmitoyl-L-ascorbate, a dough conditioner at 0.5% of the flour weight with 2.3% relative precision for different loaves. A microBondapak C-18 reverse phase column was used with methanol-water (75/25) by volume to give efficient separation. Sample preparation, digestion conditions, and the chromatographic system were optimized for maximum analyte recovery. At least 81.7% of the added dough conditioner survived bread making. With the use of a suitable detector, the procedure may be generally applicable to surfactants in bread.
