The application discloses a method for analyzing the influence of a gate dam on a river food web based on fatty acids and ecological network analysis. The method comprises the following steps: obtaining the nutrient structure of the river food web upstream and downstream of the gate dam and the measured results of fatty acids of various species through field sampling; determining the food resources and consumers of the food web through a classification library and a relationship library of nutritional groups; determining the number of nodes and the number of links between nodes in the ecological network diagram upstream and downstream of the gate dam; calculating the node size, the nutrient transmission efficiency and the interspecific energy flux in the ecological network diagram, determining the link width between nodes in the ecological network diagram, and drawing the ecological network diagram; calculating the total area of various types of nodes, the number of producer nodes and the number of consumer nodes of each nutritional group in the ecological network diagram upstream and downstream of the gate dam, and analyzing the influence of the gate dam on the key species and nutritional groups in the river food web and the influence of the gate dam on the stability and vulnerability of the river ecosystem food web.

The invention belongs to the field of allergen identification and evaluation, and particularly relates to a method for identifying animal-derived new food resource sensitizers and evaluating potential sensitization of the animal-derived new food resource sensitizers based on proteomics and bioinformatics. According to the method, the LC-MS / MS technology is used for obtaining proteome data of a target species, UniProt and AllgenOnline databases are used for performing homology comparison with known allergens, and bioinformatics tools such as AllCatPro2.0 and the like are combined for identifying the allergens in the animal-derived new food resources and evaluating the sensitization potential of the animal-derived new food resources. Proteins with sensitization risks can be rapidly screened out in a large scale at low cost through a bioinformatics method, some new sensitizers can be predicted, whether the target proteins are really expressed or not can be sensitively and accurately verified through the mass spectrum technology, and therefore the method has the advantages of being high in sensitivity and high in sensitivity. The method is a comprehensive, efficient and reliable novel food sensitization evaluation method for combination of mass spectrum-based proteomics and bioinformatics technologies.
