The utility of high performance liquid chromatography for the rapid analysis of individual free sugars in foods is demonstrated. The sucrose content of sweet corn Var. Jubilee was shown to depend on the maturity of the corn when harvested. A maximum value was obtained in corn picked 25 days after half-silk. Changes in the sugar content due to subsequent processing i.e., blanching and sulfite treatment, freeze-drying and compression were of the order anticipated. Moisture content and alcohol-insoluble solids are also reported for all samples.
