In addition to food, preservatives are also widely used in personal care products, such as lotions, shampoos, and cosmetics. Products that contain water are susceptible to microbial growth, making preservatives essential in these contexts as well. Parabens, which include methylparaben and propylparaben, are among the most commonly used preservatives in cosmetics. They serve to prolong the shelf life of products, preventing them from becoming contaminated and ensuring they remain safe for consumer use.

One of the primary functions of E200 is its application as a preservative. It is employed extensively in the food industry to inhibit the growth of mold and yeast, thereby prolonging the shelf life of products. For instance, bakers often add sorbic acid to bread and pastry products to prevent spoilage and maintain freshness. In dairy products such as cheese and yogurt, it helps to fend off unwanted microbial growth, which can lead to spoilage.

Ammonium bicarbonate is an inorganic salt that consists of ammonium ions (NH4+) and bicarbonate ions (HCO3-). This compound is soluble in water, where it dissociates into its constituent ions, which can be beneficial in multiple reactions. It has a mild alkaline nature, which makes it useful in conditions where pH adjustment is necessary. When heated, ammonium bicarbonate decomposes into ammonia, carbon dioxide, and water, making it a useful agent in various thermal processes.

In the realm of food additives, E223, also known as sodium metabisulfite, plays a significant role in food preservation and safety. This compound is a white, crystalline powder that is primarily used as a preservative, antioxidant, and bleaching agent in various food products. Its presence in the food industry often sparks discussions about its safety, functionality, and regulatory concerns, making it essential to understand its applications and implications.

4. Dough Conditioners These additives are used to improve the physical characteristics of dough, making it easier to handle and process. They can strengthen gluten, improve elasticity, and enhance water absorption. Ingredients such as ascorbic acid and enzymes fall into this category, contributing to better dough performance during fermentation and baking.

Carrageenan, a sulfated polysaccharide extracted from red seaweeds, has garnered significant attention in both the food industry and various industrial applications due to its excellent emulsifying properties. Its ability to stabilize emulsions—mixtures of oil and water that typically separate—is a key characteristic that enhances the texture, appearance, and shelf-life of numerous products.
