A simple, rapid, and accurate spectrophotometric flow-injection method was developed for the determination of sorbic acid in wines based on the oxidation of sorbic acid with K 2 Cr 2 O 7 /H 2 SO 4 at 100ЊC, followed by reaction of the resulting malonaldehyde with thiobarbituric acid, also at 100ЊC,
A method is proposed for the flow-injection determination of ascorbic acid (0.1-40 pg ml-'). Iodine is generated in the flow system as triiodide ion or the triiodide/starch complex giving a steady spectrophotometric signal at 350 or 580 nm, respectively; inverse peaks caused by ascorbic acid samples
