Dairy Process Engineering is the application of engineering principles to the production, processing, and packaging of dairy products. It focuses on designing and optimizing processes involved in transforming raw milk into products like cheese, butter, yogurt, and milk powder. The field covers thermal processing, pasteurization, homogenization, fermentation, and separation technologies. Dairy process engineers also work on ensuring energy efficiency, maintaining hygiene and food safety standards, and improving the overall quality and shelf life of dairy products. The goal is to develop cost-effective, sustainable, and scalable processes that meet industry standards while ensuring the safety and nutritional quality of dairy products.
