The manufacturing process of sodium metabisulfite typically involves the reaction of sodium hydroxide or sodium carbonate with sulfur dioxide. The reaction takes place under controlled conditions to ensure the formation of high-purity sodium metabisulfite. The production involves several stages, including the absorption of sulfur dioxide, ion exchange, crystallization, and drying. Factories utilize advanced technology and equipment to optimize these processes, minimizing waste and enhancing efficiency.

E476, commonly known as Polyglycerol Polyricinoleate (PGPR), is an emulsifier widely used in the food industry. Emulsifiers are substances that help mix two immiscible liquids, such as oil and water, by reducing the surface tension between them. E476 is derived from natural sources and is primarily used to stabilize food products, improve texture, and enhance shelf life.

In addition to its antimicrobial properties, E220 acts as an antioxidant. This means it helps prevent oxidative reactions in food that can lead to rancidity and spoilage. For example, when fruits and vegetables are exposed to air, they can brown and lose their visual appeal. Sulfur dioxide effectively slows down this oxidative process, allowing products to retain their color, taste, and nutritional value for a longer period.

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.
