Cereal processing
Common wheat (Triticum aestivum).
Cereals are a fundamental source of energy in human diets primarily due to their high starch content, which serves as a major carbohydrate energy source.12
Their importance is driven by several key factors:
- Economic Efficiency: Cereals are a low-cost energy source, with production costs per calorie lower than those of almost all other food groups.12
- Storage and Stability: Grains possess excellent keeping qualities and can be stored dry for many years, making them a reliable staple.12
- Nutritional Value: While primarily valued for energy, cereals also provide essential nutrients, including protein and minerals. Because they are energy-dense and affordable, most global diets are structured to meet primary caloric requirements through these carbohydrate-rich foods.12
By providing a consistent and accessible energy base, cereals allow for the efficient maintenance of human caloric needs, serving as the foundation for diets worldwide.2
