pasteurization

 [pas″ter-i-za´shun]
the process of heating milk or other liquids, e.g., wine or beer, to destroy microorganisms that would cause spoilage. The milk is held at 62°C for 30 minutes (LTHM, low temperature holding method, holding method), or heated rapidly to 80°C and held for 15–30 seconds (HTST, high temperature short time, flash method), and then chilled. The procedure kills most pathogenic bacteria while retaining the flavor of the liquid.

pas·teur·i·za·tion

(pas'tūr-i-zā'shŭn),
The heating of milk, wines, fruit juices, etc., for about 30 minutes at 68°C (154.4°F) whereby living bacteria are destroyed, but the flavor or bouquet is preserved; the spores are unaffected but are kept from developing by immediately cooling the liquid to 10°C (50°F) or lower.
See also: sterilization.

pasteurization

/pas·teur·iza·tion/ (pas″cher-ĭ-za´shun) heating of milk or other liquids to moderate temperature for a definite time, often 60°C. for 30 min., which kills most pathogenic bacteria and considerably delays other bacterial development.

pasteurization

(păs′chər-ĭ-zā′shən, păs′tər-)
n.
1. The act or process of heating a food, especially a beverage such as milk or beer, to a specific temperature for a specific period of time in order to kill microorganisms that could cause disease, spoilage, or undesired fermentation.
2. The act or process of destroying most microorganisms in certain foods, such as raw meat or fresh fruits and vegetables, by irradiating them with gamma rays or other radiation to prevent spoilage.

The heating of milk, wines, and fruit juice for about 30 minutes at 68°C (154.4°F), whereby living bacteria are destroyed but the flavor or bouquet is preserved; the spores are unaffected but are kept from developing by immediately cooling the liquid to 10°C (50°F) or lower.

pasteurization

A method of destroying infective micro-organisms in milk and other liquid foods. The liquid is rapidly heated to about 78 C and maintained at that temperature for fifteen seconds. It is then rapidly cooled to below 10 C. (Louis Pasteur, 1822–1895, French pioneer of bacteriology).

pasteurization

a method devised by Louis PASTEUR of partially sterilizing certain foods such as milk (by heating to 62 °C for 30 mins) before distribution. Heating destroys many harmful bacteria, including those responsible for tuberculosis. Nowadays, milk is generally pasteurized using higher temperatures (at least 72 °C, for at least 15 seconds); this is known as flash pasteurization or high-temperature short-time (HTST) pasteurization. This treatment not only kills pathogens but also reduces total bacterial counts, so that the milk will keep well in a refrigerator.

Pasteurization

The process of applying heat, usually to milk or cheese, for the purpose of killing, or retarding the development of, pathogenic bacteria.

pasteurization

the process of heating milk to destroy pathogenic microorganisms and delay the development of spoilage organisms. The holding method heats milk to at least 62.8°C (145°F) and holds it at that temperature for not less than 30 minutes. High-temperature short-time (HTST) pasteurization heats to 71.7°C (161°F) for at least 15 seconds. Ultrapasteurization heats to 88.3°C (191°F) for 1 second or 100°C (212°F) for 0.01 seconds.
