Beyond its use in food, citric acid has applications in the pharmaceutical and cosmetic industries as well. In pharmaceuticals, it is often employed as a pH adjuster and stabilizer, while in cosmetics, it serves as an exfoliant and pH balancer.

- Food Safety Preservatives help reduce the risk of foodborne illnesses caused by mold or bacterial contamination, providing an added layer of safety for consumers.

In the United States, sorbic acid and potassium sorbate are considered GRAS (generally recognized as safe) (21 CFR 182.3089; 21 CFR 182.3225; 21 CFR 182.3640; and 21 CFR 182.3795).

One of the most common categories of preservatives is antioxidants, which prevent oxidation—a process that can lead to rancidity in fats and oils, as well as the loss of flavor and nutritional value in foods. Common antioxidants include vitamin E (tocopherol) and ascorbic acid (vitamin C). These compounds help to protect sensitive ingredients in various food items, ensuring they remain fresh and enjoyable for a longer duration.

Moreover, in the field of chemistry, sodium bicarbonate is often employed in laboratory experiments as a gentle base. Its mild nature allows it to interact safely with many acids, making it an ideal reagent for teaching and experimentation. The controlled release of carbon dioxide during acid-base reactions provides a clear visual representation of these processes, facilitating learning and understanding of fundamental chemical principles.

Environmental Considerations

Consumer awareness surrounding food additives has increased significantly in recent years, leading to a greater demand for transparency in food labeling. Products containing E233 must indicate its presence, allowing consumers to make informed choices. This demand for transparency aligns with a broader trend towards clean eating and the desire for natural ingredients. As a result, some manufacturers opt for alternative preservatives that are perceived to be healthier or less chemically processed, even if E233 is deemed safe.

Acids work primarily by lowering the pH of food products. Most bacteria, yeasts, and molds thrive in neutral to slightly alkaline conditions. When the pH is lowered through the addition of acids, it creates an environment that is inhospitable for microbial growth. For instance, many pathogens become inactive or die below a certain pH level, making acidic foods safer for consumption.

2. Raw Material Costs The production of dimethyl disulfide is intricately linked to the cost of its raw materials. DMDS is primarily derived from the reaction of methanol and sulfur.
