  Baby Corn:

          

Botanical Background  Scientific Name: Zea mays L, Family: Gramineae, Genus: Zea

 

Commercially baby corn is available in two forms and two main ways of packing: in 425 g can and  in jar:

  - as 'whole spears"

  - in cut pieces

  - in vegetable mixes

 

Baby corn is a cereal grain taken from specialized sweet corn (maize) plants harvested early, while the ears are very small and immature. Baby corn ears are hand-picked as soon as corn silks emerge from the ear tips or a few days after. Baby corn ears are generally about 4.5 cm to 10 cm in length and 7 mm to 17 mm in diameter. Depending on the specifications, 13 up, 15 up till 50 up "spears" are packed in one can with a drained weight of 200 g or 225 g. The product is also available as 'cut" or 'pieces".

The product can be used as vegetable in many dishes, in stirr-fry meals, in salads as a kind of decoration, in soups.  The corn may have peppers or pimentos or other foods added for flavor or appearance.

 

At present, Thai farmers mostly use 5 varieties in their cultivation and all belong to hybrid baby corn. These are Suwan1, Suwan 2, Suwan 3, Rang sit 1 and Chiangmai 90,which have been developed to resist downy mildew, grow rapidly. Baby corn is ready for harvests after seeds germinate and grow for 45-60 days, during which the plant is in full production. It is a short-lived plant so it can bear produce only once, yielding 3-4 ears per tree. However, farmers can grow baby corn 4-5 times a year.

Main production is from Oct till June, but available all year around.
