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.
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]
Different food preservation methods have different impacts on the quality of the food and food systems. Some traditional methods of preserving food have been shown to have a lower energy input and carbon footprint compared to modern methods. [3] [2] Some methods of food preservation are also known to create carcinogens.
He developed pasteurization – the process of heating milk and milk products to destroy food spoilage and disease-producing organisms. In his research into food technology, Pasteur became the pioneer into bacteriology and of modern preventive medicine .
The most common method of pasteurization in the United States today is High Temperature Short Time (HTST) pasteurization, according to the International Dairy Foods Association. This process uses ...
Pasteur had already discovered molecular chirality, investigated fermentation, refuted spontaneous generation, inspired Lister's introduction of antisepsis to surgery, introduced pasteurization to France's wine industry, answered the silkworm diseases blighting France's silkworm industry, attenuated a Pasteurella species of bacteria to develop ...
While the traditional methods resulted in consistently increasing internal temperatures throughout the egg, the periodic method maintained a constant yolk temperature of 67 C (152.6 F), with the ...
Nicolas Appert (17 November 1749 – 1 June 1841) was a French confectioner and inventor who, in the early 19th century, invented airtight food preservation.Appert, known as the "father of food science", [1] described his invention as a way "of conserving all kinds of food substances in containers".
