In addition to traditional pickling, acetic acid serves as a versatile preservative in various food products. It is often utilized in sauces, dressings, and marinades, where it acts as a flavor enhancer while simultaneously preventing the growth of pathogens. Its antimicrobial properties are particularly effective against E. coli and Salmonella, two of the most notorious foodborne pathogens. Studies have shown that the inclusion of acetic acid can significantly reduce the microbial load in these products, thereby promoting food safety.

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.

Additives play a key role in modifying the texture and consistency of food products. Emulsifiers, such as lecithin and mono- and diglycerides, facilitate the blending of ingredients that typically do not mix well, such as oil and water. This property is essential in creating stable products like mayonnaise and salad dressings. Furthermore, thickeners and stabilizers, such as xanthan gum and guar gum, help achieve desired viscosities and mouthfeel in sauces, soups, and baked goods. The ability to control texture enhances consumer satisfaction and overall culinary experience.

Despite their advantages, some preservatives have come under scrutiny due to potential health risks. For example, studies have raised concerns about the long-term effects of consuming artificial preservatives such as BHT (butylated hydroxytoluene) and BHA (butylated hydroxyanisole). These substances have been linked to various health issues, prompting consumers to seek out preservative-free or natural alternatives. This trend has led to the emergence of 'clean label' products that tout fewer or no chemicals, appealing to health-conscious consumers.

Nisin has a variety of applications in the food industry. It is commonly used in dairy products, meats, and canned foods. In dairy products like cheese, Nisin helps prevent spoilage and maintains quality during storage. In meat products, it is effective in reducing the risk of spoilage and pathogens, thereby increasing shelf life. Moreover, Nisin is utilized in ready-to-eat meals and processed foods, where it helps to ensure food safety and extends the display life of products on supermarket shelves.
