Food engineers use their skills to design sustainable and environmentally responsible food processes for manufacturing safe, tasty, healthy, convenient food products. As consumer awareness and demand for a safe and abundant supply of food have increased so too has the need for more food engineers. Students who specialize in food engineering combine basic principles of engineering (fluid mechanics, heat transfer, and mass transfer), math, and science (biology, chemistry, and physics) with advanced courses in food chemistry, microbiology, food processing operations, and engineering design.
