I got this info on the tofutti website, includes some detailed info about how they produce their products. I found it interesting, especially since they do produce on shared lines and yet have a k-parve listing for all their products: I know all Tofutti products are Kosher Parve, which means that they contain no dairy. However, I was told that some of your products are run on equipment that also runs dairy products. If this is so, how are your products dairy free? Although we would wish it otherwise, the overall demand for totally dairy free products is not large enough to justify setting up complete production lines for dairy free products only. Most plants we use for manufacturing our products mainly produce dairy items. This is true for all companies who sell dairy free products, no matter who they are. In addition to the normal plant sterilization, cleaning, and testing procedures, we employ a kosher supervisory service, the Kof-K, to supervise the manufacturing of our products to ensure that they are completely dairy-free every time. The methodology and techniques they use to clean the equipment and supervise the production is the process called kosherization. Kosher Parve means that there are no milk (or meat) derivatives in our products. It also means that the equipment used to produce Tofutti is either dedicated to non-dairy products or has gone through the rigorous sanitation and cleaning requirements of kosherizaton. In the typical plant, the equipment is washed and sanitized with a caustic rinse and an acid rinse. The caustic rinse is done with water at boiling temperature (212 degrees Fahrenheit). This is followed by a boil-out with pure water. There are several other components to the sanitation, but they are not listed as they do not affect the kosher status. A rabbinical supervisor is present to independently verify that these procedures are being adhered to and to review logbooks and digital records to verify that these procedures are followed. If you feel that the preceding information raises your concerns about the safety of our products regarding dairy contamination, please do not use our products. Safety of our consumers is always our number one priority. For further information about kosher, please refer to our previous discussion on the subject.
