Knowra Food science Food science Food science studies food’s composition, properties, processing, safety, and preservation. It combines scientific methods to explain how foods behave and how they can be made, stored, and evaluated.
Food chemistry : The study of chemical substances and reactions in food, including changes during cooking, storage, and processing. It explains how food molecules shape flavor, color, texture, and nutritional value.
Thermal processing : The use of heat to cook, pasteurize, or sterilize food. Heat can improve digestibility and safety while also changing nutrients, flavor, and texture.
Food product development : The process of designing, testing, and scaling food products for production and consumption. It applies food science to turn formulations into consistent products.
Food preservation : Methods that slow or prevent food spoilage and keep food usable for longer. Preservation connects processing choices to storage, distribution, and reduced food loss.
Food microbiology : The study of microorganisms in food, including their roles in fermentation, spoilage, and disease. Microbes can make food, spoil it, or transmit foodborne illness.
Pasteurization : A controlled heat treatment that reduces harmful microorganisms in food without making it sterile. It extends shelf life while preserving more of a food’s original qualities than sterilization.
Food safety : The practices and conditions that prevent food from causing illness or injury. Scientific hazard control makes foods safer across production and handling.
Cold chain : A temperature-controlled supply network for storing and transporting perishable goods. Its reliability determines whether chilled and frozen foods remain safe and high-quality.
Food rheology : The study of how food materials flow and deform under applied forces. Its measurements help characterize textures such as creaminess, firmness, and spreadability.
Fermentation : A process in which microorganisms convert food components into acids, gases, alcohols, or other products. It preserves foods and develops distinctive flavors and textures.
