läbipaustamatu

läbipaustamatu is an Estonian adjective that translates to "unpasteurizable" or "that which cannot be pasteurized." This term is most commonly used in the context of food and beverage production, particularly concerning milk and dairy products. Pasteurization is a process that involves heating a liquid to a specific temperature for a set amount of time to kill harmful microorganisms, thereby extending its shelf life and making it safer for consumption.

When a product is described as läbipaustamatu, it implies that it possesses characteristics that prevent it from being effectively pasteurized without significantly altering its desired qualities or rendering it unusable. This could be due to its inherent composition, such as high fat content or the presence of specific enzymes or proteins that react negatively to heat. For instance, certain types of cheese or specialized dairy products might be deemed läbipaustamatu because pasteurization would compromise their texture, flavor, or fermentation process.

The term can also be applied metaphorically to abstract concepts or situations that are considered unchangeable, unalterable, or resistant to modification. In this broader sense, something läbipaustamatu is fundamentally resistant to the kind of "processing" or "purification" that pasteurization represents. It suggests a core essence that cannot be fundamentally altered by external forces or treatments.
