Phosphatidyl serine can be used as a stabilizer in the food processing industry, it has good emulsifying properties, can form a stable emulsion system between water and oil, in food processing, it can help stabilize emulsion, milk fat, suspension, etc., prevent its delamination and precipitation, improve product uniformity and stability. Surfactant action: Phosphatidyl serine is a surfactant that has the ability to reduce the surface tension of the liquid, by forming a film on the liquid interface, it can reduce the influence of the liquid surface tension and improve the fluidity and stability of the liquid. Phosphatidyl serine has good air hydration ability, can adsorb and retain water molecules in the air, in food processing, it can increase the water retention of products, prevent the evaporation and loss of water, improve the wetness and taste of products. Phosphatidyl serine can reduce the occurrence of fat oxidation by inhibiting the contact between oxygen and fat. In food processing, it can be used as an antioxidant to extend the shelf life of food and maintain the color, flavor and nutritional value of food. Phosphatidyl serine can interact with proteins to form stable complexes, enhance protein stability and anti-denaturation, and in food processing, it can be used to stabilize the structure of proteins and prevent protein denaturation and precipitation. Phosphatidyl serine has the characteristics of emulsification, surfactant action, air hydration, antioxidant and protein stability in food processing, making it an effective stabilizer, which can improve the texture, stability and taste of food, extend the shelf life of products, and improve the appearance and nutritional quality of products.
