Question 73

Consider the following statements:
1. Maize can be used for the production of starch.
2. Oil extracted from maize can be a feedstock for biodiesel.
3. Alcoholic beverages can be produced by using maize.
Which of the statements given above is/are correct?

AOptions

A
A) 1 only
B
B) 1 and 2 only
C
C) 2 and 3 only
D
D) 1, 2 and 3

BSolution

Maize (also known as corn) is one of the most widely cultivated cereal grains globally and has diverse applications beyond direct human consumption. Let's examine its uses:

  1. Maize can be used for the production of starch: This statement is correct. Maize is a primary source for industrial starch production. Maize starch is widely used in the food industry as a thickener, sweetener (e.g., corn syrup, high-fructose corn syrup), and in various non-food industrial applications.
  2. Oil extracted from maize can be a feedstock for biodiesel: This statement is correct. Corn oil, extracted from the germ of the maize kernel, is a vegetable oil that can be processed through transesterification to produce biodiesel, serving as a renewable fuel source.
  3. Alcoholic beverages can be produced by using maize: This statement is correct. Maize is a common fermentable carbohydrate source used in the production of various alcoholic beverages, most notably bourbon whiskey. Ethanol produced from maize fermentation is also widely used as a biofuel.

Given these widespread applications, all three statements accurately describe the uses of maize.
