In 1863, at the request of the emperor of France, Napoleon III, Pasteur studied wine contamination and showed it to be caused by microbes. To prevent contamination, Pasteur used a simple procedure:
he heated the wine to 50–60 °C
(120–140 °F), a process now known universally as pasteurization.

When did Pasteur develop pasteurization?
In
1863
, at the request of the emperor of France, Napoleon III, Pasteur studied wine contamination and showed it to be caused by microbes. To prevent contamination, Pasteur used a simple procedure: he heated the wine to 50–60 °C (120–140 °F), a process now known universally as pasteurization.
Who invented the pasteurization process?
When was pasteurization invented? About 150 years ago,
Louis Pasteur
developed the pasteurization process while he was tasked with finding practical solutions for problems such as keeping harmful bacteria at bay in different foods.
What was Louis Pasteur main discovery?
During the mid- to late 19th century Pasteur demonstrated that microorganisms cause disease and discovered
how to make vaccines from weakened, or attenuated
, microbes. He developed the earliest vaccines against fowl cholera, anthrax, and rabies.
How is pasteurization used today?
It is now used primarily in the
dairy industry for preparing milk for making starter cultures in the processing of cheese, yogurt, buttermilk
and for pasteurizing some ice cream mixes.
Why do we use pasteurization?
Why is pasteurization important? Pasteurization is important
because the bacteria naturally found in some foods can make you very sick
. Eating unpasteurized foods can lead to fever, vomiting and diarrhea. In some cases it can lead to conditions like kidney failure, miscarriage and even death.
What disease did pasteurization cure?
First developed by Louis Pasteur in 1864, pasteurization kills harmful organisms responsible for such diseases as listeriosis,
typhoid fever
, tuberculosis, diphtheria, Q fever, and brucellosis.
What bacteria can survive pasteurization?
Thermoduric bacteria
survive pasteurization temperatures (although they do not grow at these temperatures). Since they can survive pasteurization, high thermoduric bacteria counts in raw milk are particularly troublesome.
Who first pasteurized milk?
Back in 1886,
Frans von Soxhlet
, a German agricultural chemist, was the first person to suggest that milk sold to the public be pasteurized.

What did Louis Pasteur discovered in 1861?
During his experiments in the 1860s, French chemist Louis Pasteur developed modern germ theory. He proved that food spoiled because of contamination by invisible bacteria, not because of spontaneous generation. Pasteur stipulated that bacteria caused infection and disease.
What did Louis Pasteur find out?
During the mid- to late 19th century Pasteur demonstrated that microorganisms cause disease and discovered how
to make vaccines from
weakened, or attenuated, microbes. He developed the earliest vaccines against fowl cholera, anthrax, and rabies.
What are the two types of pasteurization?
- High Temperature Short Time (HTST, or simply “pasteurized”)
- Ultra-High Temperature (UHT, or ultra-pasteurized)
Are normal eggs pasteurized?
All egg products are pasteurized as required
by United States Department of Agriculture’s (USDA) Food Safety and Inspection Service (FSIS). This means that they have been rapidly heated and held at a minimum required temperature for a specified time to destroy bacteria. Further cooking is not required.
How effective is pasteurization?
Pasteurization is now defined as the process of heating every particle of milk or milk product in properly designed and operated equipment to any of the one specified pasteurization time–temperature combinations (Food and Drug Administration, 2011), most commonly 72°C for 15s, and is effective
in destroying human
