Pasteurization is the process of heat processing a liquid or a food to kill pathogenic bacteria to make the food safe to eat. The use of pasteurization to kill pathogenic bacteria has helped reduce the transmission of diseases, such as typhoid fever, tuberculosis, scarlet fever, polio, and dysentery.
Foods are heat-processed to kill pathogenic bacteria. Foods can also be pasteurized using gamma irradiation. Such treatments do not make the foods radioactive. The pasteurization process is based on the use of one of following time and temperature relationships.
High-Temperature-Short-Time Treatment (HTST) -- this process uses higher heat for less time to kill pathogenic bacteria. For example, milk is pasteurized at 161°F (72°C) for 15 seconds.
Low-Temperature-Long-Time Treatment (LTLT) -- this process uses lower heat for a longer time to kill pathogenic bacteria. For example, milk is pasteurized at 145°F (63°C) for 30 minutes.
fruit juices, fruit-based drinks, alcoholic beverages, and fermented drinks have temperatures below 100oC are used for a number of acidic products. In these acidic products, the main concern is inactivation of yeasts and molds, and in some cases heat-resistant enzymes. Generally, the shelf life of such refrigerated products is short, typically from 7 to 10 days, although this can be considerably extended if the for either reducing post processing contamination or employing aseptic processing conditions are taken
therefore; the important to note that foods can become contaminated even after they have been pasteurized. For example, all pasteurized foods must be refrigerated. If the pasteurized food is temperature-abused. it could become contaminated. Therefore, it is important to always handle food properly by handling it with clean hands, preventing it from becoming contaminated, and keeping it at a safe temperature.
