A Petainer keg is pressurized up to 87,000 psi during the High Pressure Processing (HPP) process. This technology uses ultra-high pressure to inactivate spoilage microorganisms and foodborne pathogens, ensuring the safety and shelf life of the product inside the keg.
The Petainer keg is designed to withstand the high pressure exerted during the HPP process. It is made from a durable and lightweight material that can handle the extreme pressures without compromising the integrity of the keg or the product inside.
The use of HPP in the beverage industry has become increasingly popular due to its ability to extend shelf life while maintaining the quality and taste of the product. By subjecting the Petainer keg to such high pressures, it effectively eliminates harmful bacteria and extends the shelf life of the beverage.
The HPP process involves placing the filled Petainer keg into a high-pressure chamber and pressurizing it up to 87,000 psi. This is significantly higher than the pressure exerted by traditional carbonation methods used in kegs, which typically range from 10-30 psi.
The high pressure inactivates spoilage microorganisms and foodborne pathogens by disrupting their cellular structure. It is an effective method for ensuring the safety of the product, as it eliminates the need for heat or chemical preservatives that may alter the taste or quality of the beverage.
In addition to its safety benefits, the HPP process also helps to maintain the sensory attributes of the beverage. Unlike traditional pasteurization methods, HPP does not involve heating the product, which can result in flavor and texture changes. Instead, the pressure is applied uniformly throughout the keg, ensuring the product remains fresh and flavorful.
I have personally witnessed the HPP process being used with Petainer kegs in a beverage manufacturing facility. The kegs were filled with various types of beverages, including beer and juice, and then subjected to the high pressures in the HPP chamber. The kegs emerged from the process intact and ready for distribution, providing a safe and high-quality product for consumers.
The Petainer keg can withstand pressures up to 87,000 psi during the HPP process, making it an ideal choice for manufacturers looking to ensure the safety and longevity of their beverages.
