E283

E283 is a designation that can refer to several different things, making context crucial for precise identification.

In the realm of food additives, E283 is the European Union's identification number for calcium propionate, a preservative. It is commonly used in baked goods and processed cheeses to inhibit the growth of mold and bacteria, thereby extending shelf life. Calcium propionate functions by lowering the pH of the food and interfering with microbial enzyme activity. It is generally recognized as safe by regulatory bodies when used within specified limits.

Beyond food additives, E283 might appear as a model number or catalog designation for various products or components in different industries. For instance, it could be a part number for an electronic component, a specific model of a tool, or a reference code within a company's inventory system. Without further context, it is impossible to determine the exact nature of such an E283.

The "E" prefix in E283 strongly suggests a European Union food additive classification, making calcium propionate the most likely interpretation in that specific context. However, in other fields, E283 would simply be an alphanumeric identifier without inherent meaning.
