Boiling vs. Pasteurization — What's the Difference?

Boiling, as a term, refers to the process where a liquid is heated until it reaches its boiling point, the temperature at which the liquid starts turning into vapor. Pasteurization, on the other hand, denotes a technique introduced by Louis Pasteur, where food, primarily liquids like milk, is heated to a specific temperature to kill harmful microorganisms without completely boiling the liquid.

While boiling is a general method used in cooking and can be applied to a myriad of liquids, pasteurization is tailored for food safety, specifically to extend the shelf life and ensure the product is free from harmful pathogens. Boiling is often recognized by the rapid formation of bubbles and the release of vapor from the liquid's surface, indicating that it has reached its boiling point. Pasteurization, conversely, might not display such visible cues, as the liquid does not necessarily reach its boiling point.

One significant distinction between boiling and pasteurization is the intent behind each process. Boiling primarily focuses on cooking or preparing a substance, while pasteurization emphasizes safety and the preservation of certain foods. It's also noteworthy that while boiling kills most microorganisms, some heat-resistant ones might survive, which pasteurization specifically aims to target and eliminate.

Finally, from a linguistic viewpoint, "boiling" might conjure imagery of hot, bubbling pots on a stove, whereas "pasteurization" might evoke thoughts related to milk processing or juice preservation, given its common application in these domains.
