AN-O-041
The concentration of maleic acid and kojic acid in starch through UV/VIS detection in accordance with ion-exclusion chromatography
Resumo
Evidence of maleic acid in Asian foodstuffs led to the recall of many starchy foods because long-term consumption of maleic acid can cause kidney problems. Cyclic kojic acid is however approved in Asia, both as a bleaching additive in foodstuffs and as a preservative in cosmetics. This Note describes their simultaneous determination in a single analysis.
