Pasteurization uses this principle to kill food-borne enteric food pathogens and spoiling organisms at temperatures between 140 and 158 F (60-70 C), well below boiling. HTST pasteurization means that the item being pasteurized is exposed to a High Temperature for a Short Time; thus, the HTST moniker. The scale shall have a span of at least 14C (25F) including the pasteurization temperature +/- 3C (5F), graduated in 0.25C (0.5F) divisions with not more than 4 Celsius degrees (8 Fahrenheit degrees) per 25 mm (1 inch) of span. Milk is heated to a required minimum temperature of 161F for 15 seconds and pasteurized to kill any pathogenic bacteria that may be present. The most popular methods are low temperature, HTST (high temperature, short time) and ultra-high temperature. The hold time is anywhere from 3 to 15 seconds. Conclusion.

Low-Temperature Pasteurization It also preserves the fabulous, fresh flavor of milk.

Its While it can also be done if one low-temperature process e.g 69C for 20 minutes and one HTST process is specified the temperature range is normally too large for accurate predictions and Manufacturers use various time-temperature combinations when treating their products. There has also been some progress with low temperature pasteurization methods using membrane processing technology. Extended shelf-life (ESL) or ultra-pasteurized milk is produced by thermal processing using conditions between those used for traditional high-temperature, short-time (HTST) pasteurization and those used for ultra-high-temperature (UHT) sterilization.

High Temperature Short Time (HTST) pasteurisation standard - 161oF (71.7oC) for 15 seconds - was included in the1933 edition of the U.S. Public Health Service Milk Ordinance Apart from some rounding of numbers to take account of Fahrenheit-Celsius conversions, the above standards for pasteurisation have remained unchanged to the present day This would suggest that if the pasteurization temperature for HTST milk was increased by an additional 6C, to 78C, this would provide a 5-10 log reduction for MAP depending on holding

According to the standard US protocol for the HTST pasteurization of milk, we need to use 71.7 C for 15 seconds. Boiling is not the same as pasteurization, although theyre similar. Pasteurization in the United States involves heating milk up to about 160F for the purpose of killing bacteria that could make 2021. Flash pasteurization: Also known as high-temperature short time (HTST) pasteurization. This research pertains to the development of a dynamic-model and identification of parameters for high-temperature-short-time (HTST) pasteurization process using plate-heat-exchangers for precise controller scheme for this process. The HTST pasteurization process is a continuous process accomplished by heating the product to 71.5C and passing through a holding tube at a rate that ensures the required holding time. 90 F. Pasteurization extends the shelf life of foods and beverages by slowing the growth of microbes while not completely killing them. We can distinguish: batch wise pasteurisation: 62 65C, High Temperature/Short Time (HTST) is the most common form of pasteurization in the dairy industry. Pasteurisation temperatures commonly range from 62 to 90C, and pasteurisation times vary from seconds to minutes. Two of the most common are: high-temperature, short-time (HTST), also known as flash pasteurization which typically treats at high temperatures for between three and 15 seconds; and extended shelf life (ESL).
