•Application Note: Using A Laboratory Glassware Washer To Perform Pasteurization
By Miele Professional
Pasteurization is a thermal treatment applied to foods to destroy pathogens. In the food and beverage industry, tunnel washers are often used to pasteurize bottles of beverages in a production line. Within R & D flavors laboratories, new flavors and additives are tested for heat stability prior to being used in new formulations and production. Typically, pasteurization here is performed with a bench top pasteurization system, in a stove-top immersion bath.
Specifically a G 7836 can be used instead of a typical immersion system or tunnel washer to pastuerize. A lab glassware washer simulates tunnel washer conditions–i.e. the bottles are sprayed with water at a certain temperature.
With the G 7836, temperatures can be raised step-by-step then held for a specific time interval and lowered. This temperature ramping can be customized for a particular liquid and flavor. For example, the program can be written with a number of steps, with each step raising the temperature by 10 degrees (variable) then holding a temp designated by the researcher. At first, the temperature/hold can be estimated for each step until the pasteurization temp is reached – then it needs to be determined exactly.
The holding times and temperature can be customized allowing for researchers to optimize for flavor. For example, if the material is heat sensitive, the water temperature can be held at a lower level for a longer time. Once the temperature is held, it must then be ramped down to cool the bottles.
