Sweet corn is a naturally occurring genetic variant of field corn (maize) in which sugars in the kernels convert to starch more slowly, keeping the kernels tender and sweet at harvest. While field corn is grown as a grain crop, sweet corn is treated as a vegetable and eaten at an immature stage.
Sweet corn is one of the most popular vegetables in Australia and many other countries. It can be eaten on the cob or as loose kernels, and is sold fresh, frozen, and canned. It features widely in salads, soups, stir-fries, barbecues, and as a side dish.
Maize originated in central Mexico thousands of years ago and is now one of the most widely cultivated crops on earth. Sweet corn varieties have been selectively bred for higher sugar content and longer shelf life, particularly since the development of supersweet varieties in the mid-twentieth century.
How it's produced
Sweet corn is grown as a warm-season annual crop, planted after the last frost and harvested in summer and autumn. It is typically grown in rows in open fields, requiring full sun, warm soil, and regular watering. The plants grow to around two metres tall and produce one to two ears each.
The ears are harvested by hand or machine when the kernels are plump and milky — a stage known as the milk stage. Timing is critical, as the sugars begin converting to starch soon after picking. For fresh markets, corn is often harvested in the early morning to preserve sweetness. In Australia, sweet corn is grown commercially in Queensland, New South Wales, and Victoria.
