After the production of acetic acid through any of these methods, the compound typically undergoes purification processes, such as distillation, to remove impurities and achieve the high purity levels required for glacial acetic acid. This industrial-grade acetic acid, once purified, can be cooled and appears as a clear liquid or frozen solid, depending on the temperature.

In the food industry, while glacial acetic acid itself is not directly used, it serves as a precursor for food-grade acids and flavoring agents. Acetic acid is recognized as a safe and effective preservative and is often added to pickles, sauces, and condiments. It not only helps prolong shelf life but also enhances the flavor profile of these products. In culinary applications, vinegar—a dilute solution of acetic acid—is a popular ingredient known for its ability to add tartness and complexity to dishes.
