Preservative

Navigating the world of food additives can be tricky, especially when it comes to preservatives. These substances play a crucial role in extending the shelf life of our favorite foods, preventing spoilage, and ensuring food safety. However, understanding what preservatives are, how they work, and their impact on our health is essential for making informed dietary choices.

Preservatives are broadly categorized into natural and artificial types. Natural preservatives, such as salt, sugar, vinegar, and citric acid, have been used for centuries. They work by inhibiting the growth of bacteria, yeast, and mold, which are responsible for food degradation. For example, salt draws moisture out of food, making it inhospitable to microorganisms. Vinegar's acidity creates an unfavorable environment for microbial growth, while citric acid, found in citrus fruits, acts as an antioxidant and pH regulator. Honey, with its low water activity and antimicrobial properties, has also been employed as a natural preservative.
