Starch Crops: The Unsung Heroes of Food Security and Beyond

Starch crops, often overlooked in discussions of staple foods, play a crucial role in global food security and have a wide range of applications beyond the dinner plate. These humble plants, including staples like rice, maize, and potatoes, are the primary source of carbohydrates for billions of people worldwide. Their versatility extends far beyond food, finding use in industries like textiles, paper, and biofuels. This article delves into the world of starch crops, exploring their importance, production, and diverse applications.

The Importance of Starch Crops

Starch crops are essential for human nutrition, providing a readily available source of energy.
