“Cooking can destroy nutrients, but it depends on the method of cooking. Frying and boiling leads to more nutrient loss than steaming and microwaving,” says Hafiz M. Rizwan Abid, M.S. , a ...
Both oil and water based techniques rely on the vaporization of water to cook the food. Oil based cooking techniques have significant surface interactions that greatly affect the quality of the food they produce. These interactions stem from the polar oil molecules interacting with the surface of the food. Water based techniques have far less ...
Extreme temperatures destroy viruses and vegetative cells that are active and metabolising. Organic molecules such as proteins, carbohydrates, lipid and nucleic acids, as well as cell walls and membranes, all of which play important roles in cell metabolism, are damaged by excessive heat. Food for human consumption is routinely heated by baking ...
Canning involves cooking food, sealing it in sterilized cans or jars, and boiling the containers to kill or weaken any remaining bacteria as a form of sterilization. It was invented by the French confectioner Nicolas Appert. [4] By 1806, this process was used by the French Navy to preserve meat, fruit, vegetables, and even milk.

Pasteurized milk in Japan A 1912 Chicago Department of Health poster explains household pasteurization to mothers.. In food processing, pasteurization (also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life.
Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food.This includes the study of microorganisms causing food spoilage; pathogens that may cause disease (especially if food is improperly cooked or stored); microbes used to produce fermented foods such as cheese, yogurt, bread, beer, and wine; and microbes with other useful roles, such as producing ...
Microbial metabolism is the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce.Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics.
