Abstract
For the determination of Dehydroacetic Acid in food,reversed phase C18 column was used and mobile phase was 45 % CH3OH、0.01mol/LNa2HPO4 (pH2.1-2.5) with photodiode array detecter at 310 nm. The RSD was 0.40 and the recovery rate was 98.9 %-100.0 %.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
