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.
Preserving fruit by turning it into jam, for example, involves boiling (to reduce the fruit's moisture content and to kill bacteria, etc.), sugaring (to prevent their re-growth) and sealing within an airtight jar (to prevent recontamination). Different food preservation methods have different impacts on the quality of the food and food systems.
Pasteurization is a way of extending the shelf life of food by using heat to kill the harmful bacteria. We owe a big merci to the French scientist Louis Pasteur, who made this eponymous discovery ...
Pasteurization is widely used to prevent infected milk from entering the food supply. The pasteurization process was developed in 1864 by French scientist Louis Pasteur, who discovered that heating beer and wine was enough to kill most of the bacteria that caused spoilage, preventing these beverages from turning sour. The process achieves this ...
Humans have been drinking milk from other animals for thousands of years, beginning around 10,000 years ago when farmers in early Western Europe drank the milk of domesticated cows as a new source ...
New experiments confirm milk from H5N1-infected cows can make other animals sick — and raise questions about flash pasteurization
The method became known as pasteurization, and was soon applied to beer and milk. [66] Beverage contamination led Pasteur to the idea that micro-organisms infecting animals and humans cause disease. He proposed preventing the entry of micro-organisms into the human body, leading Joseph Lister to develop antiseptic methods in surgery. [67]
