What is the difference between normal (standard) and supersweet sweet corn?
Supersweet sweet corn contains a shrunken (sh2) gene that produces about twice the amount of sugar as normal or standard varieties that contain the sugary (su) gene. It also reduces the rate of conversion of sugar to starch, so supersweets start with a higher sugar content and lose their sugar more slowly. The fresh market now demands supersweet varieties, and although many processing varieties are the normal types the quantity of sh2 sweet corn grown for processing is increasing.
