Knowra Food engineering Food engineering Food engineering applies engineering principles to processing, preserving, packaging, storing, and distributing food while maintaining safety, quality, and efficiency.
Heat transfer : The movement of thermal energy between materials or regions at different temperatures. Heating and cooling steps determine how quickly food reaches safe temperatures and how much quality it retains.
Food drying : The removal of water from food to reduce weight and limit spoilage. Drying combines heat and mass transfer to extend shelf life.
Food chemistry : The study of the chemical composition, reactions, and properties of food. Chemical changes during processing affect flavor, color, nutrition, and stability.
High-pressure processing : A preservation method that subjects packaged food to very high hydrostatic pressure. It can inactivate microbes with less heat than conventional thermal processing.
Food safety : The practices and conditions that prevent food from causing illness or injury. Process design and validation determine whether hazards are controlled consistently.
Fluid mechanics : The study of how liquids and gases move and exert forces. It describes pumping, mixing, and flow through pipes in food-processing plants.
Food freezing : The preservation of food by lowering its temperature until much of its water freezes. Freezing slows microbial and chemical changes while requiring careful temperature control.
Food microbiology : The study of microorganisms associated with food, including their growth and effects. Microbial behavior sets constraints for safe processing and storage.
Irradiation of food : The treatment of food with ionizing radiation to control microbes, insects, or sprouting. It offers a preservation route distinct from heating, though its uses are tightly regulated.
Shelf life : The period during which a food remains suitable for use under stated storage conditions. Preservation and packaging choices set how long products retain safety and quality.
