The growth in the food and beverage sector has led to a heightened demand for flavor enhancers, with MSG playing a significant role. Consumers are increasingly seeking products that not only save time but also offer great taste. MSG enhances umami flavor, which is recognized as one of the five basic tastes, alongside sweet, sour, bitter, and salty. This umami-rich taste profile is particularly appealing in a variety of applications, from snacks to sauces, thereby increasing the usage of MSG in various culinary practices around the world.
Sodium benzoate is a widely used food preservative known for its ability to inhibit the growth of mold, yeast, and some bacteria. As a sodium salt of benzoic acid, it is often recognized by its chemical formula C7H5NaO2. Although sodium benzoate has emerged as a key player in food preservation, its applications extend well beyond the culinary world, infiltrating various industries such as pharmaceuticals, cosmetics, and even agriculture.
According to the World Health Organisation, substances that are added to food to maintain or improve the safety, freshness, taste, texture or appearance of food are known as food additives. For centuries, food additives have been used to preserve food, for example salt (in meat, bacon or dried fish), sugar (in marmalade) or sulphur dioxide (in wine).
The importance of primary emulsifiers cannot be overstated, as they ensure the consistency and quality of emulsions. In the food industry, for example, they allow for the creation of stable salad dressings, mayonnaise, and sauces that do not separate over time. In cosmetics, they help formulate creams and lotions that maintain a smooth texture and even distribution of ingredients. In pharmaceuticals, effective emulsifiers are crucial for the development of drug delivery systems that require a stable mixture of oil-based and water-based components.
In recent years, there has been a growing interest in exploring alternative, less conventional methods of meat preservation. Techniques such as high-pressure processing (HPP), vacuum packaging, and the use of natural antioxidants like rosemary extract have gained traction. HPP, for instance, exposes meat to high pressures, which can effectively kill harmful bacteria without compromising nutritional value or altering taste. Similarly, vacuum packaging removes oxygen, one of the main catalysts for spoilage, thereby prolonging freshness.
