Does flash pasteurization destroy nutrients?
No. The HTST process only kills the pathogenic bacteria and slows down the natural oxidation process, but does harm or affect the nutrient content of the juices, as opposed to full pasteurization which requires that the juices be maintained at high temperatures for a longer period of time.
What is the advantage of flash pasteurization?
Flash pasteurization is especially beneficial to maintain the natural flavor, color and nutritional compounding of liquid products such as fruit juices and milk. This method can further expand the shelf life of products compared to the traditional pasteurization method.
Is flash pasteurized the same as pasteurized?
Flash pasteurization is considered to be a middle ground between raw and ultra-pasteurized. The process quickly heats the juice to a specific temperature, holds it there for a few seconds then quickly cools it, affecting the taste less than the longer process of traditional pasteurization.
Does flash pasteurization sterilize the milk?
The standard US protocol for flash pasteurization of milk, 71.7 °C (161 °F) for 15 seconds in order to kill Coxiella burnetii (the most heat-resistant pathogenic germ found in raw milk), was introduced in 1933, and results in 5-log reduction (99.999%) or greater reduction in harmful bacteria.
Is flash pasteurized juice safe during pregnancy?
Only drink pasteurized juices. This makes them unsafe for pregnant women.Mar 15, 2017
What does lightly pasteurized mean?
Subject: What does "gently pasteurized" mean? Anonymous. It's flash pasteurization. Essentially, the juice goes from cold to 165 degrees to cold again in less than 60 seconds. This keeps nutrients, etc., intact in juice.Jul 26, 2013
Is unpasteurized juice safe?
Unpasteurized juice may contain harmful bacteria that could make some people sick. To help consumers identify unpasteurized juice and cider, the Food and Drug Administration requires a warning on juice and cider.Sep 12, 2014
Does flash pasteurized juice need to be refrigerated?
“Any time a beverage label says 'keep refrigerated,' that's there for safety purposes, and it's essential that you do that,” Andress said. “Most juices are pasteurized, which is not enough heat to destroy the spores of C. botulinum if they're there.Oct 26, 2006
What is the flash method of pasteurization?
Flash Pasteurization is a form of High Temperature, Short Time (HTST) pasteurization that has gained popularity in recent years. Liquid is brought to a higher temperature than Hot Filling for a shorter amount of time (usually 15-30 seconds), then rapidly cooled before being filled into the aseptic packaging.
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 ...

There are several different methods of pasteurization.
Is pasteurization still used today?
Today, pasteurization is used widely in the dairy industry and other food processing industries to achieve food preservation and food safety.
What is flash heating?
Flash-heating (FH) 1 is a low-tech method of pasteurizing breastmilk that was developed for HIV positive lactating parents in developing countries who had no safe nor affordable alternatives for feeding their infants.
What temperature does breast milk need to be to be flash heated?
While the temperature of breastmilk when flash-heating typically reaches 72ºC/161.5ºF, 4 this is not as accurate as with the FP process.
What is HTST Pasteurization?
HTST pasteurization refers to high-temperature short-time processing, also known as flash pasteurization, or the “continuous method.” Pasteurizing perishable beverages such as fruit and vegetable juices, beer, wine, and some dairy products, such as milk using heat.
Why is HTST Pasteurization the most common method?
An HTST pasteurization system is a modular unit that comprises a stainless steel balance tank, a plate-and-frame heat exchanger, pumps, valves, holding tube, piping, and controls. The holding method, also known as VAT pasteurization, is the oldest method of pasteurizing food.
How HTST pasteurization works
HTST pasteurization is a newer variation of the traditional procedure, but it is based on the same fundamental principle. Rather than heating the container of food or liquid, as in traditional pasteurization, the batch of liquid is heated as it is poured into sterile containers.
Benefits of HTST Pasteurization
Flash pasteurization is useful for preserving certain products’ flavor, color, and nutritional value, such as fruit juices. When compared to traditional pasteurization, this method can increase the shelf life of certain products.
Drawbacks of HTST Pasteurization
Because of the technology involved, flash pasteurization is a much more expensive process than the traditional method.
Frequently Asked Questions
Benefits. HTST pasteurization is useful for preserving certain products’ flavor, color, and nutritional value, such as fruit juices. When compared to traditional pasteurization, this method can increase the shelf life of certain products.
Conclusion
HTST pasteurization is an effective method of making beverages safe to consume without significantly altering their sensory or nutritional properties. As a continuous process, it uses energy regeneration and can operate at scales and with energy efficiencies that other processes cannot match.
