What temperature and how long is tunnel pasteurization?

Views: 521 Update date: Aug 01,2023
Tunnel pasteurization is a heat-based process used to destroy harmful microorganisms in packaged food and beverages. The method involves passing product-filled containers through a temperature-controlled tunnel, where they are subjected to specific heat treatment before cooling. The cornerstone of successful tunnel pasteurization lies in selecting the right temperature range. Temperatures that are too low may fail to eliminate all pathogens, while excessively high temperatures risk compromising the taste and nutritional value of the products. The recommended temperature range for tunnel pasteurization typically falls between 120°F to 170°F (49°C to 77°C). However, precise temperatures vary depending on the specific product, container material, and targeted pathogen elimination. Striking the right balance between time and temperature ensures that harmful microorganisms are neutralized without compromising the product's integrity.

Tunnel pasteurization times can range from a few minutes to several minutes. The process involves a thorough understanding of heat transfer dynamics to ensure every product receives the necessary thermal treatment.
