Is Corn a Starch?

Very specific answer to raised question is, "Yes!", corn is a starchy vegetable. The debate over corn being a vegetable or starch arises as a result of different ways of using it for consumption. This plant is used both for the purpose of obtaining grains and the vegetative part (especially the sweet corn). Speaking about the grains obtained from corn, these are similar to other types of grains. Starch/carbohydrates are presented in corn grains just like in other grains. However, if the corn plant (most commonly the sweet corn) is harvested prematurely and used for consumption, it is classified as vegetable. Let us understand, is corn a starch or a vegetable through this article.

Corn: Starch or Vegetable

The grains of corn are actually fruits which originate from the reproductive part of the plant. Therefore, it becomes clear that corn is not a vegetable. The word, vegetable is however, not scientific and is commonly used in different culinary traditions.

Starch
It is one of the types of carbohydrates that is formed of glucose units. The glycosidic bonds connect these glucose units to each other. These polysaccharide structures connected by glycosidic bonds are the fundamental units of starch. Starch is the important energy source of plants. The color of pure starch is white. This substance is odorless and tasteless. The different molecules which compose the starch are amylopectin and helical and linear amylose. Percentage of amylopectin in starch is greater than linear and helical amylose. The percentage of amylose and amylopectin in starch is 20-25% and 75-80% respectively. The green plants obtain energy from sunlight and convert it into sugar. This sugar is converted into starch; granules of starch are formed and stored in the grains of plants. The process of conversion from sugar to starch takes place with the help of enzymes.

Cornstarch
The starch obtained from the corn kernel i.e. its endosperm is referred to as cornstarch. Thomas Kingsford isolated the cornstarch in the year, 1840. Earlier, the starch obtained from corn was used only for industrial purposes and laundry use. This starch find use in the preparation of liquid-based foods; it is used as a thickening agent in the preparation of these items.

Vegetable
The vegetables are those plants in which the leaves or other vegetative parts (stem, root) are used for edible purpose. Reproductive part of the plant is not consumed as vegetable. Corn grains cannot be termed as a vegetable according to the above description. This is because the edible part of this plant is the grains produced on cobs. Grains are actually fruits and therefore, the reproductive part of this plant.

Corn is a Starchy Vegetable
It is said that corn is a starchy vegetable; this is because both the vegetative and reproductive part (fruit/grain) are used for consumption. Sweet corn is used for its vegetative part as well as grains. The other varieties are mainly used for obtaining grains. The use of both reproductive part (grains) and vegetative part for consumption allows for naming this plant as a starchy vegetable. This plant also contains nutrients like proteins and vitamins (C, B9, B5, etc.). It also contains dietary fibers necessary for maintaining the digestive health of our body.

Vegetables Containing Starch
The information about different vegetables containing starch given below should answer the question, "Is corn a starch or vegetable?", in a better manner. In vegetables like peas, dried beans, potatoes, plantains, soybeans and lima beans carbohydrate content is greater than that of other vegetables.

Some people find it confusing to determine whether corn is a starch or vegetable. Plants have both vegetative and reproductive parts. It is the part that we make use of determines whether a plant is a vegetable or grain.
