Notes:
Cooked sweet corn aroma volatiles were analyzed by gas chromatography using a headspace technique. Aroma profiles of corn from early and late plantings, different stages of maturity, different cultivars, and different processes were submitted to stepwise discriminant analysis (BMD-0–7M). Processes were most often classified correctly with slight overlaps between brine-pack canned cron and vacuum-packed canned corn and more notable overlapping between frozen and vaccum frozen corn. Corn from different plantings were classified correctly about two-thirds of the time on the basis of their aroma profiles. Stylepak and NK199 cultivars were most often classified correcltly; similarities expressed in overlapping classifications were apparent among Butersweet, Silver Queen NK199 and among code 556, Buttersweet and Silver Queen. Fancy grade corn was correctly classified about 45% of the time, extra standard about 67% of the time, and standard about 68% of the time. By strafifying the data by processing method prior to discriminant analysis, improved classification was achieved for cultivars and maturities.
