What are the main in diet soda?

Artificial sweeteners: Diet sodas are sweetened with artificial sweeteners, which are synthetic chemicals that mimic the taste of sugar but contain few or no calories. Common artificial sweeteners used in diet sodas include aspartame, sucralose, acesulfame potassium, and saccharin.

Carbonated water: Diet sodas are made with carbonated water, which gives them their fizzy texture. Carbonated water is created by dissolving carbon dioxide gas in water under pressure.

Flavorings: Diet sodas are typically flavored with natural and artificial flavors, which give them their specific taste. Common flavors used in diet sodas include cola, lemon-lime, root beer, and cherry.

Preservatives: Diet sodas often contain preservatives to extend their shelf life. Common preservatives used in diet sodas include sodium benzoate, potassium sorbate, and calcium disodium EDTA.

Acidity regulators: Diet sodas may contain acidity regulators to balance their pH levels and improve their taste. Common acidity regulators used in diet sodas include citric acid, phosphoric acid, and malic acid.

Mineral fortifiers: Some diet sodas are fortified with vitamins and minerals, such as calcium, magnesium, and vitamin C. Fortification can help improve the nutritional value of diet sodas, but it's important to note that they still contain artificial sweeteners and other additives.

It's worth noting that the exact ingredients in diet sodas can vary depending on the brand and flavor.
