Natural preservatives are substances derived from natural sources that help extend the shelf life of food by preventing spoilage. Common examples include salt, sugar, and vinegar, which inhibit the growth of bacteria and mold. These preservatives are often preferred over synthetic options because they are generally considered safer and healthier. In addition to traditional methods, some natural preservatives come from plants, such as rosemary extract and citric acid. These compounds not only preserve food but can also enhance flavor and provide antioxidant benefits. Using natural preservatives is a growing trend in the food industry, as consumers seek cleaner and more wholesome products.
