Young corn ears are immature cobs of maize (Zea mays) which are unfertilized. It is harvested before or just after the silk has emerged (1-3 cm). Its regular size is between 2-4 inches long and ⅓-⅔ inch in diameter at base [3]. It is often enjoyed as vegetable, perhaps due to its delicate flavour and crispiness. Although it commonly used in Asian cuisine, young corn ear is now gaining its popularity abroad. In the previous study, young corn ear was found to be as nutritious as other vegetables such as cabbage, cauliflower, tomato, eggplant and cucumber [4] and [5]. They reported that protein and minerals in young corn ear were comparable with the vegetables.
