Potassium sorbate is a commonly used preservative with antimicrobial properties often used as preservatives in food and drinks to prevent the growth of mold, yeast, and fungi. In general the potassium sorbate is preferred over the sorbic acid because it is more soluble in water, but the active form is the acid. The optimal pH for the antimicrobial activity is below pH 6.5. Sorbates are generally used at concentrations of 0.025% to 0.10%. Adding potassium sorbate to food will, however, raise the pH of the food slightly so the pH may need to be adjusted to assure safety. It is found in foods such as various kinds of cheese, bread, muffins, donuts, pies, cookies, protein bars, syrups, lemonades, fruit juices, dried meats, sausages, nuggets, burgers, sandwiches, tacos, pizzas, smoked fish, margarine, sauces, soups, and more.

Despite its many advantages, it is essential for consumers to remain informed about the food additives they consume. While E901 has a strong safety record, transparency in labeling allows individuals to make educated choices about their diets and any potential allergens or additives they might wish to avoid.

In industrial applications, 2-butyne is primarily used as an intermediate in organic synthesis. Its versatile reactivity allows chemists to create a variety of derivatives that can be further transformed into valuable products. Additionally, due to its high energy content, 2-butyne is explored as a potential fuel source.

Though any listed ingredient is FDA-approved or classified generally regarded as safe, groups like the American Academy of Pediatrics have called into question the agency's approval processes and effects on children's health. Others take issue with the chemicals used in extracting food ingredients from natural sources.

In some cases, ascorbic acid is added to foods to fortify them with additional vitamins. This is especially common in processed foods and beverages where nutrients may be lost during manufacturing. By fortifying products with ascorbic acid, manufacturers can offer enhanced nutritional benefits to consumers, promoting overall health and well-being.

Food additives play an essential role in the modern food landscape, contributing to preservation, flavor enhancement, visual appeal, texture improvement, and nutritional fortification. While they offer significant advantages in food production, the dialogue surrounding their safety and the demand for more natural products remains vital. As consumers' tastes and concerns evolve, the food industry will continue to adapt, striving for a balance between innovation, safety, and transparency in ingredient use.
