Yes, fish roe can be pasteurized. Pasteurization is a process used to kill harmful bacteria in food and beverages by heating them to a certain temperature for a set period of time. This process helps ensure that the product is safe to consume and extends its shelf life. Fish roe can be pasteurized either before or after it has been processed into products such as caviar or taramasalata. The pasteurization method used will depend on the type of roe being treated, with some methods using temperatures up to 160°F (71°C) for 30 minutes, while others may require higher temperatures and longer periods of time in order to effectively eliminate any potential pathogens.
