Abstract: At present,the emergence of products such as concentrated canned soup and driedpacket of soup on the market represents the depth of modern food science and technology research on the taste,nutrition and shelf life of soup,but the research on the functionality of soups has rarely been reported. The research on the function of soup should be based on the research on the efficacy of soup,however,the main factor of the efficacy is the micro/nanoparticles(MNPs).In this paper,the types of main components of micro-nanoparticles in soup,the rules of nutrients migration from food materials to soup and the possible formation mechanism of MNPs are reviewed,so as to understand the relationship between micro-nanoparticles in soup and human health.
