What is White Corn?

History of White Corn

The scientific name of corn is Zea Mays which is a grain crop and belongs to the grass family called Garminae. White corn is native to America specifically Mexico that is not only grain but also considered as fruit and vegetable.

  • It is considered as a grain because it is a dry seed of a species of grass
  • It is considered as a vegetable when it is harvested before maturity
  • It is considered as a fruit because according to the botanical definition it is the seed bearing part of a flowering plant

During the Age of Discovery, white corn became very popular due to its versatility as a crop and can grow in a wide variety of climate conditions.

Taste & Appearance

Most people believe that white corn is a variety of sweet corn with a higher sugar than the starch ratio.

The ears or body of white corn is tightly wrapped with pale lime green to white husks and one ear of corn contains up to 400 kernels growing in rows lengthwise. Unlike yellow corn, both the milk and kernels of white corn are creamy in color due to the presence of two recessive Y alleles.

Key Difference

  1. White corn is white in color due to the presence of two recessive Y alleles that do not produce carotenoids (the plant pigment responsible for red, orange, and yellow colors in many fruits and vegetables) while yellow corn is yellow in color due to the presence of single dominant Y allele.
  2. White corn contains less lutein while yellow corn contains more lutein.
