The application of phospholipids in functional foods

Phospholipids are essential bioactive substances with both hydrophilic polar heads and hydrophobic nonpolar tails, endowing them with unique amphiphilic properties that find widespread applications in the food industry. The increasing prevalence of phospholipids in functional foods is primarily attributed to their distinctive physicochemical characteristics and biological functionalities.

In functional foods, phospholipids are commonly employed as emulsifiers. Leveraging their dual nature of water and oil affinity, phospholipids facilitate the mixing and stabilization of emulsions, playing a crucial role in various food manufacturing processes such as sauces, bread, pastries, chocolates, and avocados. The addition of phospholipids helps maintain stable textures and flavors in these foods, enhancing product quality and shelf life.

Phospholipids also exhibit antioxidant properties in functional foods, aiding in reducing oxidative reactions during processing and storage. This antioxidative function has led to the widespread use of phospholipids in baked goods, confectioneries, and hydrogenated vegetable oils, effectively extending the shelf life of these products.

Furthermore, phospholipids serve as excellent nutritional supplements, containing abundant fatty acids and nutrients like phosphatidylcholine. They provide essential nutrients to the human body, leading to their wide application in infant formula, elderly nutrition supplements, and athlete dietary supplements.

Simultaneously, phospholipids contribute to improving the taste and texture of food products. Adding phospholipids to baked goods such as bread, cakes, and cookies enhances the texture and mouthfeel, making the products softer, moister, and more delectable.

The increasing prevalence of phospholipids in functional foods stems from their irreplaceable position in the food industry, driven by their unique physicochemical properties and biological functionalities. As the demand for functional foods continues to rise, the future prospects of phospholipids in the food industry appear promising. However, it is essential to consider the dosage and safety of using phospholipids as food additives to ensure their rational application in food products.
