What causes corn to turn brown during processing?


Corn often turns brown during processing as a result of caramelization of sugar. The sweeter the corn at the time it is canned, the more likely it is to turn brown. The long processing time required for corn packed in quart jars also tends to darken it. Processing corn in pint jars might prevent darkening. Although canned corn that has turned brown is unattractive, it is safe to eat.
