Flavorings play a prominent role in defining the taste of food products. They can be either natural, derived from plant or animal sources, or artificial, created through chemical processes. The use of flavor enhancers, such as monosodium glutamate (MSG), has sparked debate among consumers regarding their safety and potential health implications. While many regulatory bodies assert that these additives are safe in moderation, some individuals report sensitivity to certain flavorings, making it essential for food manufacturers to inform consumers adequately.
In addition to its use in food preservation, sodium benzoate finds applications in various other industries. In cosmetics, it is used as a preservative to prolong the shelf life of products such as shampoos, lotions, and creams. In the pharmaceutical sector, sodium benzoate is included in medications not only for its preservative properties but also for its role in maintaining the stability of active ingredients. Moreover, it acts as a flavoring agent and a corrosion inhibitor in certain formulations.
Despite the advantages, the use of sulphur dioxide as a food preservative has raised health concerns, particularly regarding allergic reactions in certain individuals. Some people, particularly those with asthma, may experience respiratory issues or other adverse effects when consuming foods containing SO₂. As a result, regulatory agencies in many countries, including the United States Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), have established limits on the amount of sulphur dioxide that can be used in food products. Moreover, items containing sulphites (the salts of sulphur dioxide) must be properly labeled, ensuring that sensitive individuals can make informed choices.
