What does HTST stand for in milk?
High Temperature Short Time
Pasteurization Type The most common method of pasteurization in the United States today is High Temperature Short Time (HTST) pasteurization, which uses metal plates and hot water to raise milk temperatures to at least 161° F for not less than 15 seconds, followed by rapid cooling.
What is the difference between Ltlt and HTST pasteurization?
There are two types of pasteurization known as HTST and LTLT. The key difference between HTST and LTLT is that HTST method uses a high temperature and a short time for the pasteurization, whereas LTLT method uses a low temperature and a long time for the pasteurization.
What is HTST?
HTST systems allow a high volume of production in a minimum of processing space. The ability of HTST pasteurizers to assure a safe milk or milk product relies on the time-temperature-pressure relationships that must be maintained whenever the system is in operation.
What is HTST sterilization?
Also known as high-temperature–short-time (HTST) processing, aseptic canning is a process whereby presterilized containers are filled with a sterilized and cooled product and sealed in a sterile atmosphere with a sterile cover.
Is UHT and HTST the same?
HTST pasteurization heats the milk to 161 degrees Fahrenheit for 15 seconds and then rapidly cools it to 39 degrees. For UHT, raw milk is heated to approximately 280 degrees Fahrenheit for just 2 seconds and is then rapidly chilled back to 39 degrees. Both methods result in milk that is 99.9% free of bacteria.
What is the meaning of UHT and HTST?
UHT Pasteurization and HTST Pasteurization are typically defined as follows: High Temperature/Short Time (HTST) Pasteurization. HTST Pasteurization is by far, the preferred method of pasteurization, where the product is heated to 72 °C for approx. 15 seconds. Ultra-High Temperature (UHT) Pasteurization.
What is Batch pasteurization?
The terms “batch pasteurization”, “vat pasteurized” and “low heat pasteurized” shall mean the process of heating every particle of milk or milk product, in properly designed and operated equipment, to a minimum temperature of 69ºC (155ºF) and held continuously at or above that temperature for at least 30 minutes.
Is it safe to drink UHT milk?
UHT milks are really just as nutritious as fresh milk with a longer shelf life; you can even store them at room temperature or in the refrigerator if your child prefers drinking them chilled. However, do take note that it should be refrigerated and consumed within five days after opening.
