Abstract:Long-term high-sodium diets are directly related to a variety of health problems, including increase of blood pressure and incidence of cardiovascular diseases. As people's health awareness increases, salt reduction actions are imminent, savory-enhancing peptides have become an ideal low-sodium substitute due to their own unique advantages, which is of great significance for the development of salt reduction products and has a wide range of application prospects. The development of animal-derived savory-enhancing peptides can not only make efficient use of animal products (such as chicken bones, cattle bones, shrimps and crabs), but also serve as efficient salt substitutes, showing great development potentialand high application value. Therefore, the research and development of animal-derived savory-enhancing peptides have become a current research hotspot in the field of food science. In this paper, the sources, preparation technologies, separation and purification technologies, identification techniques, and application status and prospects of animal-derived savory-enhancing peptides are reviewed, in order to provide a reference basis and theoretical support for the in-depth study of animal-derived savory-enhancing peptides, and the research and development of related salt-reducing products in the future.
