Tartósítószer

Tartósítószer (plural: tartósítószerek) is a Hungarian term that translates to "preservative" in English. These substances are added to food, beverages, and other consumable products to prevent spoilage, inhibit microbial growth, and extend shelf life. The main categories of preservatives include chemical additives, natural extracts, and physical methods such as refrigeration and vacuum packaging.

Chemically derived preservatives, such as sodium benzoate, sorbic acid, and nitrates, were developed in the early 19th century and have become widespread in processed foods. Natural preservatives include salt, vinegar, sugar, essential oils, and plant extracts like rosemary and thyme, which offer antimicrobial properties through mechanisms such as pH reduction and antioxidant activity. Physical preservation techniques, while not chemical additives, are often listed in product labels as they contribute to the overall preservative strategy.

Regulatory agencies around the world classify and approve preservatives based on safety studies, acceptable daily intake limits, and efficacy data. In the European Union, the European Food Safety Authority (EFSA) maintains a list of approved preservatives, each with specified maximum levels in specific food categories. In the United States, the Food and Drug Administration (FDA) regulates the use of food additives through the Food Additives Amendment of 1958 and the Food Manufacturing Practice Act.

Public concern regarding the potential health effects of synthetic preservatives has led to increased demand for natural alternatives. Studies indicate that while many synthetic preservatives are safely consumed within regulated limits, some individuals may experience hypersensitivity reactions. Research continues to refine preservative use, balancing food safety with consumer health and preferences.
