{'maize': [2, 1, 1, 2], 'biodiesel': [0, 0, 1, 3], 'production': [16, 4, 20, 51], 'starch': [1, 0, 0, 0], 'alcoholic beverages': [0, 0, 1, 0], 'feedstock': [0, 0, 0, 1], 'oil': [8, 3, 14, 21]}

All three statements are correct.

1. Maize is a major source of starch which is used in a wide range of food and industrial applications. Maize starch is extensively used in the food industry as a thickener, stabilizer, and binder. It is also used in the production of paper, textiles, adhesives, and cosmetics.

2. Maize oil is a rich source of triglycerides and can be used as a feedstock for biodiesel production. The oil is extracted from maize germ which is a byproduct of maize milling. The use of maize oil as a feedstock for biodiesel production has gained popularity due to its low cost and high availability.

3. Alcoholic beverages can be produced by fermenting maize. In many countries, maize-based alcoholic beverages such as beer and whiskey are popular. The process involves fermenting the sugars present in maize using yeast, which converts the sugars into alcohol.
